我怀疑有几件事，虽然不确定.

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

首先也是最显而易见的是，通往Tesseract的道路并不完整.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，尽管只有您可以确认.让我知道这是否是错误的，我也看到其他一开始似乎并不正确的东西，但还需要更多调查.

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.
