pip install fails

Hi Joao,

Thanks for reporting the issue. I am currently working on it, but it might take me a little while to figure out how to fix the problem.

In the meantime, there are two temporary solutions that you can use on your side:

• If you do not need the new particle tracking functionality, then you can roll back to version 0.4.0 of openPMD-viewer:

pip install openPMD-viewer==0.4.0

which should install without any problem.

• Another option is to use conda to install openPMD-viewer:

conda install -c rlehe openpmd_viewer

The conda install works even with the new version that has particle tracking.

@RemiLehe Thanks for the fast reply.
The problem with pip was solved by installing scipy via pip beforehand. Then we could install openPMD-viewer without any problems.

OK, thanks for letting me know. That's hard to explain, but I'm glad it worked anyway.

In the meantime, I identified other problems with the install, and fixed them in PR #143 . There should be less installation problems once this is fixed.

@RemiLehe Thanks for fixing the problem so fast.
Perhaps scipy installed Cython - or our attempt to install openPMD by hand required Cython and we thus installed it. I do not remember and I have no access to @joaobranco17 system right now to check it.
