Sorry to bother. I just looked in to the command now. Now I Updated the command. Try that once again.

@spgoutham ensure that you correctly installed fairseq. Check that python can see it through
python
then
import fairseq shouldn't display any errors. As for me, it reveals that additional package install was required.
Then if you are using venv, ensure that you are installing package within your venv:

source .venv/bin/activate
python -m ensurepip --upgrade
pip install git+https://github.com/One-sixth/fairseq.git

Specially this way

This isn't working for me. I still get the same error. I installed python through homebrew and it is using pip3. I uninstalled fairsec and then reran pip3 install git+https://github.com/One-sixth/fairseq.git

before installing worked!

That’s dope. Is it kind of the best version of Python, cause I saw it fixes many bugs?

I found some package can only run under <python 3.11

So, what is it? Is RVC going to work?

Why do I generate incorrect file names and numbers when I use fairseq, which can be used in a higher version of python?
