问题
I'm using pandas/python to save a DataFrame in a HDFStore format. When I apply the my_data_frame.to_hdf(arguments...) command I have an error message:Warning! ***HDF5 library version mismatched error *** and my program is stopped.
I'm working on Windows 7 (64bits), using Python 3.5.2 :: Anaconda 4.1.1 (64-bit).
I've been reading about this error message and as it says it's a problem between the version of HDF5 installed on my computer and the one used by Anacondas. According this post, a simple "conda install -c anaconda hdf5=1.8.18" could resolve my problem but I'm still having the same message error.
Thanks for your help guys.
Here I put a complete log of the error:
Warning! ***HDF5 library version mismatched error***
The HDF5 header files used to compile this application do not match
the version used by the HDF5 library to which this application is linked.
Data corruption or segmentation faults may occur if the application continues.
This can happen when an application was compiled by one version of HDF5 but
linked with a different version of static or shared HDF5 library.
You should recompile the application or check your shared library related
settings such as 'LD_LIBRARY_PATH'.
You can, at your own risk, disable this warning by setting the environment
variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'.
Setting it to 2 or higher will suppress the warning messages totally.
Headers are 1.8.15, library is 1.8.18

回答1:
Headers are 1.8.15, library is 1.8.18
Your error information shown this, so you need install the 1.8.15 version.
conda install -c anaconda hdf5=1.8.15

This fixed it for me, hope it helps.
Step one
pip uninstall h5py
Step two
pip install h5py
回答3:
In case someone is having this problem and no amount of uninstalling with pip or conda or anything will work: I went through every /lib path and manually deleted libhdf5* files, then installed hdf5 with macports.
回答4:
The only procedure that worked for me on macOS was to create a virtualenv:
virtualenv -p python3 myenv
. myenv/bin/activate
pip3 install h5py==1.10.4 # or whichever version you want
Absolutely nothing else worked!
You may need a brew install hdf5
