Warning! ***HDF5 library version mismatched error*** python pandas windows

Question

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

Answer 1

Try to uninstall h5py module and install it again. This fixed it for me

1. pip uninstall h5py
2. pip install h5py

Answer 2

 Headers are 1.8.15, library is 1.8.18

Your error information shows, then, that you need install the 1.8.15 version.

conda install -c anaconda hdf5=1.8.15
