Running this code

How did you install QuTiP? I installed a fresh copy with conda and I do have spmatfuncs.
Are you building from source?

How did you install QuTiP?

In the FreeBSD, after QuTiP has been built, I run python -c "import qutip.testing as qt; qt.run();", and it fails.

[yurivict]

Once installed, running

import qutip.testing as qt
qt.run()

fails:

Python Version:     2.7.15
Traceback (most recent call last):

The last error is fixed by this PR: #895

The first error (missing spmatfuncs) is still there.

[ajgpitch]

The first error generally occurs if you are running qutip from within the directory where you installed it

[yurivict]

Ok, thanks, I made it to run in the port by supplying PYTHONPATH to the build directory.

This issue could be closed if all is fixed.
