I am trying to launch this simple gradio voice recording interface. It runs fine on Google Colab, but the same code acts differently from the command line and in Pycharm.

I am installing whisper with

pip install git+.git

I also install

ffmpeg-python

On the command line the execution hangs and once the process is killed, I get the output that I would have seen had it not been hanging as :

$ python test_audio_delay.py  <--- hangs after this line until process is killed.

Keyboard interruption in main thread... closing server.

If I run it in PyCharm, the filename (which is the voice recording) is captured, but I still get an error indicating "file cannot be reached", and I use the `local URL'

See error below:

• I installed FFmpeg using Chocolate. This allowed the script to successfully run in PayCharm, but I am still unable to run it from the command line. The FFmpeg bin folder is added to system Path as well. When executing form the command line, there is no response until the process is killed at which time we get the normal output about the local and public URLs followed by killed process. – Nader Afshar Commented Apr 1 at 20:11

The resolution turned out to be related to the use of Git Bash shell. Switching to a windows command shell solved the problem.
