Python OpenAI Whisper FileNotFoundError when running a standalone created with PyInstaller

I made a small Python program that uses OpenAI whisper's library. Everything works fine in my virtual environment.

I generated a .exe of the whole thing with PyInstaller, but when I run the resulting file, I get the following error:

Exception ignored in thread started by: <function start_interpretor at 0x000001F9EC80F430>
Traceback (most recent call last):
  File "interpretor.py", line 67, in start_interpretor

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Div-o\\AppData\\Local\\Temp\\_MEI236562\\whisper\\assets\\mel_filters.npz'

I have tried to add the datas object to the .spec file generated by PyInstaller:

a = Analysis(
//...
datas=[('.venv/Lib/site-packages/whisper/assets/mel_filters.npz', '.venv/Lib/site-packages/whisper/assets'),],
//...
)

I even added recursive_copy_metadata="whisper" to the EXE() in the same file, but the issue persists.

Any idea what is causing that?

Solution

I solved it by using faster-whisper.

Also your datas should probably look like this:

a = Analysis(
//...
datas=[('.venv\\Lib\\site-packages\\whisper\\assets\\mel_filters.npz', '\\whisper\\assets'),],
//...
)
