To fix the issue when using pandas HDFStore class, upon creating an HDFStore object:
x = HDFStore(‘test.h5’) Warning! HDF5 library version mismatched error
or if you get a similar error upon
import h5py, then apply the following upgrade(s)
Windows/Mac/Linux/WSL (NOT Cygwin)
conda install --upgrade pandas pytables h5py
or if not using Anaconda Python:
pip install --upgrade pandas tables h5py
We assume you have installed Pip in Cygwin.
setup-x86_64 -P python3-devel gcc
Start Cygwin with Run As Administrator.
/usr/bin/pip3 install --upgrade h5py
This will take several minutes, as often Numpy will be upgraded as well.
