How to feed ghostscript DLL library to python in Windows?

Background. I'd like to use camelot.read_pdf(file) which uses ghostscript.

  1. The project has ghostscript package.
  2. Windows 10 got installed Ghostscript 9.54.0 for Windows (64 bit). 2.1. c:\Program Files\gs\gs9.54.0\bin has been added to system PATH env variable.
  3. Python 3.9 64 bit.

The required library path is c:\Program Files\gs\gs9.54.0\bin\gsdll64.dll.
But python does not “see” it. As it's, probably, not loaded in the system.

  File "C:\Users\USERNAME\.virtualenvs\PROJECT\lib\site-packages\camelot\backends\ghostscript_backend.py", line 31, in convert
    raise OSError(
OSError: Ghostscript is not installed. You can install it using the instructions here: https://camelot-py.readthedocs.io/en/master/user/install-deps.html

So, how it should work? Which step did I miss?

Solved.

First, Python can find DLL by paths from environment PATH variable. So, the path c:\Program Files\gs\gs9.54.0\bin has to be presented there.

PyCharm (or another IDE) has to be reloaded (that's my main mistake).

Thanks @Petesh to the comment.
