Installing h5py on OS X

问题

I've spent the day trying to get the h5py module of python working, but without success. I've installed HDF5 shared libraries, followed the instructions I could find on the web to get it right. But it doesn't work, below is the error message I get when trying to import the module into python. I tried installing through MacPorts too but again it wouldnt work.

I'm using Python27 32 bits (had too for another module, and thus installed the i386 HDF5 library... if that's right?)

Any help very welcome !

Thank you !

回答1:

Check that you are not inside the h5py installation directory.

回答2:

My advice, if you can, install h5py using Anaconda Distribution Open Data Science Core.
