我通过命令pip3 install snowflake-connector-python[pandas]==2.3.3 asn1crypto==1.3.0 --user安装了雪花连接器
我尝试通过连接
from snowflake import connector
con = connector.connect(
host='.snowflakecomputing.com',
user='THE USER I USE FOR LOGGING IN TO MY TRIAL ACCOUNT',
password='THE PASSWORD I USE FOR LOGGING IN TO MY TRIAL ACCOUNT',
account='zka81761.us-east-1',
warehouse='COMPUTE_WH',
database='DEMO_DB',
schema='PUBLIC',
protocol='https',
port=443)
当执行上面的代码时，它只挂了几分钟，然后我得到了一个错误：
snowflake.connector.errors.OperationalError: 250003: Failed to execute request: encoding with 'idna' codec failed (UnicodeError: label empty or too long)
较长的版本是：

这个错误消息告诉我什么都没有，任何帮助都将被认为是
根据python API上的文档，不再使用host字段，请尝试删除该字段。此外，即使它被使用过，你也没有把它正确地放在引号里：
您有：host='.snowflakecomputing.com,
应为：host='.snowflakecomputing.com',
首先，我想看看删除主机是否完全解决了您的问题，因为无论如何都不应该使用它。
在谷歌上搜索错误和错误消息本身表明，问题是由于URL太长，所以我认为错误是由于您没有正确地将其附上。
我曾经从python连接雪花，如下所示：
import snowflake.connector as sf
sfconnection = sf.connect(
user='THE USER I USE FOR LOGGING IN TO MY TRIAL ACCOUNT',
password='THE PASSWORD I USE FOR LOGGING IN TO MY TRIAL ACCOUNT',
account='zka81761.us-east-1',
warehouse='COMPUTE_WH',
database='DEMO_DB',
schema='PUBLIC')显然文档是错误的，host现在应该是完整的URL(在我的例子中是zka81761.us-east-1.snowflakecomputing.com(。也就是说，它应该包括account。
