Difference in installed vs reported module version.

Hi,

I created an environment with conda. Executing `pipreqs . ` creates the `requirements.txt` file reporting `scipy==1.14.0`. But when checking with `pip3 list | grep scipy` is shown `scipy==1.13.0`. Similar with another module. Any idea on why this occurs?

Thanks.

No files or tests are mentioned. Start by reproducing the discrepancy in a conda environment, comparing pipreqs output with `pip3 list`, and tracing how each version is obtained. Done means identifying why the versions differ and adding a verified fix or documented explanation.
