I am trying to install pytrec_eval package using this command python -m pip install pytrec_eval but it fails with the following error: ‘ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1133)’. I am trying to install it in a conda environment with python=3.9 on a Linux machine (Ubuntu 9.4.0).

Here is the log of the error:
