import order causes numpy/core/getlimits.py to throw UserWarning in cmssw-11.2.0-python3 Docker image

This Issue is just to note strange behavior of imports.

In the pyhf/pyhf-combine-converter:cmssw-11.2.0-python3 Docker image environment, if uproot is imported before pyhf then it will cause numpy/core/getlimits.py to throw UserWarning: The value of the smallest subnormal for <class 'numpy.float64'> type is zero. and UserWarning: The value of the smallest subnormal for <class 'numpy.float32'> type is zero.
