Code worked after I made changes in requirements file. I got following 2 exceptions with versions for numpy & pandas -

ERROR: No matching distribution found for numpy>=1.25.0
ERROR: No matching distribution found for pandas>=2.1.0

After I removed the version, everything worked fine.

I have 3.8 version. That explains the error.
