浏览具有2页文本Book的图像(.jpg)文件，并提取文本以保存为.txt文件(两个文件都在本地文件夹中)

Question

我正在使用Ms Azure凭据计算机视觉访问图像文件并从中提取文本，最后将其保存在。txt文件中。代码工作良好的url具有。jpg扩展名。我的代码在

中出现了一些错误

1. 扩展名为。jpg的图像文件保存在本地文件夹中。
2. 图片文件从web与url做。没有。jpg扩展名。

我的代码在这里-in-under

'''url of the remote (web) Image File'''
#remote_image_url = "https://raw.githubusercontent.com/Azure-Samples/cognitive-services-sample-data-files/master/ComputerVision/Images/landmark.jpg"
#imagefile = "<filepath>//IMAGE1.JPG"
remote_image_url = "http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg"

with open('C://Users//ubana//OneDrive//ANIL JOSHI//PROJECTS//CONVERSION TO TXT FILE//IMAGES//pic1.jpg', 'wb') as handle:
response = requests.get(pic_url, stream=True)
if not response.ok:
print (response)
for block in response.iter_content(1024):
if not block:
break
handle.write(block)
'''

print("===== Describe an image - remote =====")
# Call API
description_results = computervision_client.describe_image(remote_image_url)
# Get the captions (descriptions) from the response, with confidence level

print("No description detected.")
else:
for caption in description_results.captions:

错误如下

如果有人能帮我解决这个问题，我将不胜感激

文件路径似乎有错误

with open('C://Users//ubana//OneDrive//ANIL JOSHI//PROJECTS//CONVERSION TO TXT FILE//IMAGES//pic1.jpg', 'wb') as handle:

是不正确的。也许可以尝试在文件路径中使用双反斜杠而不是正斜杠，如下所示:

with open('C:\Users\ubana\OneDrive\ANIL JOSHI\PROJECTS\CONVERSION TO TXT FILE\IMAGES\pic1.jpg', 'wb') as handle:
