ModuleNotFoundError: No module named 'past'

**Hi all,

I need some help with the folowing : I installed Subsai as showed in the Readme file, and then I ran the example script in python :**

`from subsai import SubsAI

file = 'C:/Users/acer/Desktop/vocalrem/Final/video1.mp4'
subs_ai = SubsAI()
model = subs_ai.create_model('openai/whisper', {'model_type': 'base'})
subs = subs_ai.transcribe(file, model)
subs.save('test1.srt')`

And I got the following in my console :

Traceback (most recent call last):

**I tried to fix it in every way I could think of, but to no avail (I have "Future" library installed).

Do you have any suggestions. Thanks in advance.**

Hi @Benazid,

Basically, installing the future module should solve this past issue. Which is weird why it is not working!

I can see from the error that you are using Python 3.11. I suggest to downgrade to 3.10 and retry ? Maybe ffmpeg-python is not yet compatible!
