title: Warning! ***HDF5 library version mismatched error*** python pandas windows
body: <p>I'm using pandas/python to save a DataFrame in a HDFStore format. When I apply the <em>my_data_frame.to_hdf(arguments...)</em> command I have an error message:<strong>Warning! ***HDF5 library version mismatched error</strong> *** and my program is stopped.</p>
  
  <p>I'm working on Windows 7 (64bits), using Python 3.5.2 :: Anaconda 4.1.1 (64-bit).</p>
  
  <p>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 <a href="https://github.com/h5py/h5py/issues/853" rel="noreferrer">this</a> post, a simple <strong><em>"conda install -c anaconda hdf5=1.8.18"</em></strong> could resolve my problem but I'm still having the same message error.</p>
  
  <p>Thanks for your help guys.</p>
  
  <p>Here I put a complete log of the error:</p>

      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
