Problems installing using pip in fresh python 3.9 environment

[hans-vg]

I created a fresh python 3.9 environemnt and tried to install with the provided pip3 command. However, it is failing during the build process.

Successfully built upsetplot
Installing collected packages: pytz, zipp, six, pyparsing, pillow, packaging, numpy, kiwisolver, fonttools, cycler, python-dateutil, contourpy, pandas, matplotlib, upsetplot, seaborn, sniffles2-plot
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
botocore 1.34.131 requires urllib3<1.27,>=1.25.4; python_version < "3.10", which is not installed.
