I searched and found some suggestions, among them is to add JAVA_HOME to the environment variable, but I have not used JAVA at all.

这是关于你错误原因的解释：
File "C:\Users\Bouregag Youcef\AppData\Local\Programs\Python\Python311\Lib\site-packages\jpype_jvmfinder.py", line 212, in get_jvm_path raise JVMNotFoundException("No JVM shared library file ({0}) " jpype._jvmfinder.JVMNotFoundException: No JVM shared library file (jvm.dll) found. Try setting up the JAVA_HOME environment variable properly.
不管你的脚本中是否直接使用Java - 你导入的某个模块可能需要Java。它尝试查找某种jvm文件，可能引用了JAVA_HOME变量以实现这一目的。看起来在你的环境变量中没有正确设置它。你可以通过在搜索栏中键入“编辑系统环境变量”来检查它并打开它。在我的情况下，它设置为C:\Program Files\Java\jdk-17.0.5.8-hotspot\，其中jdk-17.0.5.8-hotspot是Java安装文件夹。

This is the explanation what is the reason of your error:
File "C:\Users\Bouregag Youcef\AppData\Local\Programs\Python\Python311\Lib\site-packages\jpype_jvmfinder.py", line 212, in get_jvm_path raise JVMNotFoundException("No JVM shared library file ({0}) " jpype._jvmfinder.JVMNotFoundException: No JVM shared library file (jvm.dll) found. Try setting up the JAVA_HOME environment variable properly.
It does not matter that you do not use Java in your script directly - one of your imported modules does though. It tries to find some kind of jvm file and probably refer to JAVA_HOME variable to achieve it. It looks as if it is not set correctly in your Environment Variables. You can check it by typing in search bar Edit the system environment variables and opening it. In my case it is set to C:\Program Files\Java\jdk-17.0.5.8-hotspot\ where jdk-17.0.5.8-hotspot is Java installation folder.

我通过下载和安装JDK，最后将其添加到名为"JAVA_HOME"的环境变量中，解决了这个问题。

I solved the problem by downloading and installing jdk and finally adding it to environment variable with name "JAVA_HOME"
