我怀疑一些事情，但不确定.

I suspect a few things, not sure about any though.

首先，也是最明显的，Tesseract 的路径并不完整.它应该是这样的:

First and the most obvious, the path to Tesseract is not complete. It should be something like:

tesseract_cmd = 'C:\Program Files (x86)\Tesseract-OCR\tesseract'

我相信您的路径指向目录/文件夹而不是可执行文件，但只有您可以确认.如果这不正确，请告诉我，我也看到了一些乍一看不正确的内容，但需要更多调查.

I believe your path points to a directory/folder and not an executable, though only you can confirm that. Let me know if this is incorrect, I see something else too that doesn't seem right at first, but needs more investigation.
