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 SUMMARY OF THE HDF5 CONFIGURATION ================================= General Information: ------------------- HDF5 Version: 1.8.18 Configured on: 2017-05-31 Configured by: NMake Makefiles Configure mode: CMAKE 3.8.0 Host system: Windows-6.3.9600 Uname information: Windows Byte sex: little-endian Libraries: Installation point: C:/bld/hdf5_1496269860661/_b_env/Library Compiling Options: ------------------ Compilation Mode: RELEASE C Compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/amd64/cl.exe CFLAGS: /DWIN32 /D_WINDOWS /W3 H5_CFLAGS: AM_CFLAGS: CPPFLAGS: H5_CPPFLAGS: AM_CPPFLAGS: Shared C Library: YES Static C Library: YES Statically Linked Executables: OFF LDFLAGS: /machine:x64 AM_LDFLAGS: Extra libraries: C:/bld/hdf5_1496269860661/_b_env/Library/lib/z. lib Archiver: Ranlib: Debugged Packages: API Tracing: OFF Languages: ---------- Fortran: OFF Fortran Compiler: Fortran 2003 Compiler: Fortran Flags: H5 Fortran Flags: AM Fortran Flags: Shared Fortran Library: YES Static Fortran Library: YES C++: ON C++ Compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/amd64/cl.exe C++ Flags: /DWIN32 /D_WINDOWS /W3 /GR /EHsc H5 C++ Flags: AM C++ Flags: Shared C++ Library: YES Static C++ Library: YES Features: --------- Parallel HDF5: OFF High Level library: ON Threadsafety: ON Default API Mapping: v18 With Deprecated Public Symbols: ON I/O filters (external): DEFLATE MPE: Direct VFD: dmalloc: Clear file buffers before write: ON Using memory checker: OFF Function Stack Tracing: OFF Strict File Format Checks: OFF Optimization Instrumentation:
This fixed it for me, hope it helps.
Step one
pip uninstall h5py
Step two
pip install h5py
