Install h5py without sudo - python-2.7

Question

I'm trying to install h5py package via pip for python 2.7, I can't use sudo and I have python 3.2 installed too.
Here is my attemp:
I have installed pip:
curl -O https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py --user
then I installed wheel
~/.local/bin/pip2.7 install --user wheel
Collecting wheel

Answer 1

So there's a few things happening here:
Missing SSL certificate problems (see the urllib3 link)
setuptools not finding wheel, meaning a wheel isn't built, so pip calls python setup.py install directly
h5py is trying to use a function in HDF5 which does not exist in the version of HDF5 that's on your system.
1 and 2 are worth fixing (as they may be symptoms of other problems with the system), but 3 is the reason h5py isn't working for you.
h5py is trying to access H5Oexists_by_name. According to https://www.hdfgroup.org/HDF5/doc/RM/RM_H5O.html#Object-ExistsByName, this first appeared in version 1.8.5 of HDF5. According to http://packages.ubuntu.com/source/precise/hdf5, the version of HDF5 on your system is 1.8.4 (but you need to check this!). Somehow h5py thinks the HDF5 library on you system is 1.8.5 or higher (see https://github.com/h5py/h5py/blob/4ee8f89b6dc658fdea5dc62d0f29058121928cfe/h5py/h5o.pyx#L172)
It looks like someone else has run into a similar problem, and filed https://bugs.launchpad.net/ubuntu/+source/hdf5/+bug/1418220. You probably want to inform them of your problem, so that they can produce a bug fix.
