run_test.py failures

OS Debian Linux (Stretch) Setup: Anaconda3

While testing the sfepy installation ( ./run_tests.py --debug tests/test_projections.py) the following two files errored out with "ImportError: No module named ". as an example. The two files were:

test_projections.py and test_input_navier_stokes2d_iga.py

Not sure what is causing this. All of the other files passed.
