pip install ffcv does not work!

[Akash-Samanta]

Having trouble installing the ffcv package using pip. Got this log:
Collecting ffcv
Using cached ffcv-1.0.2.tar.gz (2.6 MB)
error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> See above for output.

note: This error originates from a subprocess, and is likely not a problem with pip.
Preparing metadata (setup.py) ... error
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

Tried alternate way of cloning locally and then installing from it:
Neither 'setup.py' nor 'pyproject.toml' found.

This is likely because you are missing dependencies or their dev headers.
If you're on linux, try:

sudo apt-get update
sudo apt-get install libopencv-dev pkg-config libturbojpeg0-dev
pip install opencv
