Smoke and tear gas swirled through parts of Paris and Nantes as protests turned violent.Union leaders said public workers should maintain their industrial action until Tuesday when they urged members to flood the streets once again.“Unions will meet on Tuesday evening to decide on our next actions if by then Macron and (Prime Minister) Edouard Philippe has not reversed course and opened negotiations,” Catherine Perret of the hard-left CGT union told reporters.The strike pits Macron, a 41-year-old former investment banker who took office in 2017 on a promise of opening up France’s highly regulated economy, against powerful unions who say he is set on dismantling worker protections.“We’re going to protest for a week at least, and at the end of that week it’s the government that’s going to back down,” said 50-year-old Paris transport employee Patrick Dos Santos.The outcome depends on who blinks first – the unions who risk losing public support if the disruption goes on for too long, or the president whose two-and-a-half years in office have been rocked by waves of social unrest.Macron’s pension tsar Jean-Paul Delevoye is due to hold talks with the unions on Monday before the prime minister presents the broad outlines of the proposal to the public mid-week.Education Minister Jean-Michel Blanquer said far-reaching reform was needed to put the generous pension system on a sustainable footing. Fewer teachers went on strike on Friday, education ministry data showed.“It would be much easier for us to do nothing,” Blanquer told BFM TV. “We could see through this five-year term without enacting deep reform. But if every presidency reasons in this way, our children will not have an acceptable pension system.”Police had used tear gas in central Paris on Thursday afternoon when hooded protesters on the fringes of the trade unions’ march threw fireworks at officers, ransacked bus stops, and set fire to rubbish bins.More than 800,000 people rallied in protests countrywide on Thursday. Union leaders put the numbers higher.“There’s a noise in the streets, I hope the windows of the Elysee are open,” said Philippe Martinez, secretary-general of the CGT union, referring to the president’s office.Macron wants to simplify the unwieldy pension system, which comprises more than 40 different plans. Rail workers and mariners can, for instance, retire up to a decade earlier than the average worker.The president says the system is unfair and too costly and that the French will have to work longer, though he appears reluctant to simply raise the retirement age of 62.One alternative is to curb benefits for those who stop working before 64 and give a benefits boost to those who leave later.",
"The French -- and particularly Parisians -- are face to face with what may be the largest strike in the country's history.On the heals of the Yellow Vest protests, employees of various sectors are preparing to go on indefinite strike beginning Thursday to protest pension reforms by the government of French President Emmanuel Macron.The walkout was sealed when the government announced its determination to implement pension reform despite pushback.According to France’s National Institute of Statistics and Economic Studies, Macron has further fueled the sense of anger and rebellion among French people against their presidents, with his economic policies that have given the wealthy a greater share of national income since his inauguration on May 17, 2017.He has been facing the biggest crisis since the yellow vest protests.The reform would lift the privileges granted to civil servants and gradually increasing the retirement age from 62 to 64. It is expected to adversely affect many sectors.Long list of strikersAmong the strikers will be employees of national carrier Air France, state-owned Parisian public transport operator RATP, electricity company EDF that is largely owned by the government, state-owned national railway firm SNCF, and automobile manufacturer Renault.Police, healthcare professionals, teachers, lawyers, taxi and freight drivers, postal workers, farmers, civil servants, refinery workers and students will also participate.Over half of all schools across the country will be suspended, while nearly all commuter trains and buses will halt and or work in intermittently. Air France will cancel 30% of its flights.The Yellow Vest protests started Nov. 17, 2018 in reaction to rising fuel costs and economic injustice, later spiraling into deadly anti-government riots.Protesters used yellow vests, part of the standard safety kit in French cars, to make their members more easily visible.The demonstrations left 11 dead and more than 4,000 injured including protesters and the police, according to government figures.Activists claim that 24 protesters were blinded in one eye and that five lost one of their hands.At least some 8,400 people have been arrested since the beginning of the Yellow Vest protests, and 2,000 were remanded into custody.A total of 17 protestors were arrested in Toulouse and five people -- two police and three civilians -- were injured.",
"PARIS-The Eiffel Tower shut down, France’s vaunted high-speed trains stood still and several thousand people protested in Paris as unions launched open-ended, nationwide strikes Thursday over the government’s plan to overhaul the retirement system.Paris authorities barricaded the presidential palace and deployed 6,000 police as activists - many in yellow vests representing France’s year-old movement for economic justice - gathered in the capital in a mass outpouring of anger at President Emmanuel Macron and his centerpiece reform.Unions and their supporters fear that the changes to how and when workers can retire will threaten the hard-fought French way of life. Macron himself remained “calm and determined” to push it through, according to a top presidential official.The Louvre Museum warned of strike disruptions, and subway stations across Paris shut their gates. Many visitors - including the U.S. energy secretary - canceled plans to travel to one of the world’s most-visited countries amid the strike. Unprepared tourists discovered historic train stations standing empty Thursday, with about nine out of 10 of high-speed TGV trains canceled. Signs at Paris’ Orly Airport showed “canceled” notices, as the civil aviation authority announced 20% of flights were grounded.Some travelers showed support for the striking workers, but others complained about being embroiled in someone else’s fight. “I had no idea about the strike happening, and I was waiting for two hours in the airport for the train to arrive and it didn’t arrive,” said vacationer Ian Crossen, from New York. “I feel a little bit frustrated. And I’ve spent a lot of money. I’ve spent money I didn’t need to, apparently.”Vladimir Madeira, a Chilean tourist vacationing in Paris, said the strike has been “a nightmare.” He hadn’t heard about the protest until he arrived, and transport disruptions foiled his plans to travel directly to Zurich.Beneath the closed Eiffel Tower, tourists from Thailand, Canada and Spain echoed those sentiments. Bracing for possible violence along the route of the Paris march, police ordered all businesses, cafes and restaurants in the area to close. Authorities banned protests in the more sensitive neighborhoods around the Champs-Elysees avenue, presidential palace, parliament and Notre Dame Cathedral.Police carried out security checks of more than 6,000 people arriving for the protest and detained 65 even before it started. Embassies warned tourists to avoid the protest area. The mood was impassioned in the crowd massed on Boulevard Magenta in eastern Paris.Health workers showed up to decry conditions in hospitals. Students pointed to recent student suicides and demanded government action. Environmentalists emphasized that climate justice and social justice are one and the same. And young and old roundly condemned the new retirement plan, which they fear would take money out of their pockets and reduce the period of repose the French expect in the last decades of their lives.Eric Mettling, who joined the yellow vests at the start of their movement, said the general strike had brought together social movements across France in a manner unprecedented in recent memory to denounce “the social crisis.”Skirmishes broke out between police firing tear gas and protesters throwing flares at a protest in the western French city of Nantes, and thousands of red-vested union activists marched through cities from Marseille on the Mediterranean to Lille in the north.Lacking public transport, commuters used shared bikes or electric scooters despite near-freezing temperatures. Many workers in the Paris region worked from home or took a day off to stay with their children, since 78% of teachers in the capital were on strike.The big question is how long the strike will last. Transport Minister Elisabeth Borne said she expects the travel troubles to be just as bad Friday, and unions said they’ll maintain the Paris subway system strike at least through Monday. Public sector workers fear Macron’s reform will force them to work longer and shrink their pensions. Some private sector workers share their worries, while others welcome the reform.Joseph Kakou, who works an overnight security shift in western Paris, walked an hour to get home to the eastern side of town Thursday morning. “It doesn’t please us to walk. It doesn’t please us to have to strike,” Kakou told The Associated Press. “But we are obliged to, because we can’t work until 90 years old.”To Macron, the retirement reform is central to his plan to transform France so it can compete globally in the 21st century. The government argues France’s 42 retirement systems need streamlining. While Macron respects the right to strike, he “is convinced that the reform is needed, he is committed, that’s the project he presented the French in 2017” during his election campaign, the presidential official said. The official was not authorized to be publicly named.After extensive meetings with workers, the high commissioner for pensions is expected to detail reform proposals next week, and the prime minister will release the government’s plan days after that.",
"Protesters mobilized across France on Thursday in a nationwide strike challenging President Emmanuel Macron’s controversial pension reform plans.The Interior Ministry said 806,000 people took part, while labor unions put the number at nearly 1.5 million.Some 250,000 people took part in the protests in Paris, where police used smoke bombs to disperse the crowd.The unlimited strike impacted all public transport systems in the country, according to local media reports.A total of 90 people have been arrested so far in Paris, police said.Some train, subway and bus services were canceled and many schools were closed while the law and order situation led to the cancelation of 20% of flights to the country.In a tweet, the Paris Police Department said it had conducted 6,476 checks. Labor unions said the strike will continue until Monday.The Gare du Nord, a station of the SNCF railway network in Paris, was almost empty in the morning, according to broadcaster France 24.Protesters, however, made their way to the Gare du Nord in the afternoon to attend the main march to Place de la Nation square.They included police, healthcare professionals, teachers, lawyers, taxi and freight drivers, postal workers, farmers, civil servants, refinery workers and students, according to the Le Monde daily.The walkout came after the government announced its determination to implement pension reform despite a nationwide outcry.According to France’s National Institute of Statistics and Economic Studies, Macron has further fueled the sense of anger and rebellion among French people against their president with his economic policies that have given wealthy people a greater share of national income since his inauguration on May 17, 2017.He has been facing the biggest crisis since the beginning of the Yellow Vest protests in October last year.Proposed reformFrance currently has 42 different pension programs for different sectors, but the government proposed to unify them into one pension scheme.France’s current program is based on the principle of solidarity between generations under which the working population finances the pensioners of that year.But due to the aging population, fewer people are paying into the current system.To fix this, the government introduced a point-based system that would compensate workers with pension points for every day they work or every euro they contribute.The reform would lift the privileges granted to civil servants and gradually increase the retirement age from 62 to 64, a move expected to adversely affect many sectors.Workers will get a full pension if they retire at the age of 64. If they retired before, they would lose 5% of their pensions for every year they retire early.They would also gain a 5% increase in their pensions for every year if they retire after the age of 64.The demonstrations and strikes have been supported by numerous labor and police unions as well as the Yellow Vests.Macron paused his overseas visits for a while to focus on a solution to the problems caused by the strikes and demonstrations.",
"Paris-A strike over planned pension reforms that paralysed France on Thursday has entered its second day.Several unions, including rail and metro workers, voted to extend the strike action, meaning another day of major disruptions to key services.It comes after more than 800,000 people protested on Thursday, with violent clashes reported in a number of cities.Workers are angry about planned pension reforms that would see them retiring later or facing reduced payouts.France currently has 42 different pension schemes across its private and public sectors, with variations in retirement age and benefits. President Emmanuel Macron says his plans for a universal points-based system would be fairer, but many disagree.Rail workers voted to extend their strike through Friday, while unions at the Parisian bus and metro operator said their walkout would continue until at least Monday.Numerous rush-hour trains into Paris were cancelled on Friday and 10 out of 16 metro lines were closed, while others ran limited services, Reuters news agency reports.Traffic jams of more than 350km (217 miles) were reported on major roads in and around the capital.A number of flights have also been disrupted, while many schools are expected to remain shuttered and hospitals understaffed. Protesters sang songs against President Macron in ParisMr Macron’s government has reportedly made plans to deal with the strike action at the weekend.Some trade union leaders have vowed to strike until Mr Macron abandons his campaign promise to overhaul the retirement system.“We’re going to protest for a week at least, and at the end of that week it’s the government that’s going to back down,” 50-year-old Paris transport employee Patrick Dos Santos told Reuters.What happened on Thursday?French police gave the figure of 800,000 people taking to the streets across the country, including 65,000 in Paris. Union leaders put the numbers higher, with the CGT union saying 1.5m people turned out across France.The disruption meant popular tourist sites in Paris, including the Eiffel Tower, were closed for the day and usually busy transport hubs like the Gare du Nord were unusually quiet.",
"Paris (AFP): France was on Saturday expecting its most serious nationwide strike in years to paralyse the country over the weekend, with unions warning the turmoil would last well into next week.",
"PARIS: The French government on Friday expressed determination to plough ahead with far-reaching pension reforms in the face of the biggest strikes in years, which have brought public transport in much of the country to a standstill.The strikes, which began on Thursday, have seen most high-speed trains cancelled, flights affected and most of the Paris metro shut down in a major challenge to the ambitious reform agenda of President Emmanuel Macron.The turmoil is expected to continue over the weekend and through until at least Tuesday when unions have called more nationwide protests to follow mass rallies on Thursday that brought over 800,000 people onto the streets.With Macron not yet speaking publicly about the strikes and seeking for now to rise above the fray, Prime Minister Edouard Philippe insisted that the government would not abandon a plan which would require the French “to work a bit longer.” He pledged to work with trade unions to introduce a single “fairer”, points-based pension scheme for all, scrapping the 42 more advantageous plans currently enjoyed by train drivers, soldiers and a host of other workers in the process.The centre-right premier added that the government was “very determined” to implement the reform, adding he did not believe the French would always accept a situation where some retire earlier, and with more money than others doing comparable jobs.But he emphasised that the changes, which he said would be unveiled on Wednesday, would be introduced “progressively, without harshness”. “My logic will never be one of confrontation,” he said.Dozens of trains, metros and flights were cancelled, many schools were again closed or offering only daycare, and four of the country’s eight oil refineries remained blocked on Friday.Rail operator SNCF has already halted ticket sales through the weekend, with 90 percent of high-speed TGV trains again cancelled on Friday and little improvement expected over the weekend.Half of the Eurostar trains between Paris and London were dropped, and just two of three Thalys trains serving Paris, Brussels and Amsterdam were running.“I was supposed to take a train to Metz (northeast France), I reserved my ticket three days ago but it’s been cancelled and I’ve gotten no information,” Rachel Pallamidessi said at a deserted station in the city of Strasbourg.Several airlines cancelled flights as air traffic controllers walked off the job, with Air France cancelling 30 percent of domestic flights and 10 percent of nearby international routes.In Paris, nine of the capital’s 16 metro lines were shut while many others were running only during rush hours, prompting commuters to turn to bicycles, electric scooters and other alternatives or to work from home.It remains to be seen if the protests will match the magnitude of the 1995 strikes against pension overhauls when France was paralysed for three weeks from November to December, ultimately forcing the government to back down. The walkout is the latest test of Macron’s mettle after months of protests from teachers, hospital workers, police and firefighters, capping a year of social unrest triggered by the “yellow vest” protest movement.Unions say Macron’s proposal for a single pension system would force millions of people in both the public and private sectors to work well beyond the official retirement age of 62.At least 800,000 took part in rallies around the country on Thursday, according to the interior ministry, one of the biggest demonstrations of union strength in nearly a decade.Another day of strikes and rallies has been called for Tuesday, a day after union leaders are to meet again with government officials over the pension reform.“There were lots of people on strike, now we need even more if we want to influence these decisions,” Philippe Martinez of the hard-line CGT union told LCI television.While most of the rallies were peaceful, police fired tear gas to disperse dozens of black-clad protesters smashing windows and throwing stones during the Paris march, with one construction trailer set on fire.Several dozens of people were arrested, and three journalists were injured after reportedly being hit by tear gas or stun grenades, including a Turkish journalist who was struck in the face.Published in Dawn, December 7th, 2019Copyright © 2019, DawnScribe Publishing Platform",

我刚刚遇到和你一样的问题。从我的测试来看，数组(包含您的句子)的最小长度似乎必须是10。
我发现了这一点，因为我第一次尝试使用BERTopic使用长度为11的数组，第二次尝试使用长度为7的数组失败。
然后我测试了我的假设，即长度是第一个数组的问题。我逐渐将它的大小缩小了1，并将其反馈到模型中。当我的数组长度为9时，我得到了错误。
