After installing Anaconda and fenics on CentOS 6.6 or 7, I am having an issue.
Running "from dolfin import *"

Fails with the error: $ python template_timedep.py Vendor: Continuum Analytics, Inc. Package: mkl Message: trial mode expires in 30 days

Hello @jonmilby, could you please try python -c "import ffc"? This error is very common and has nothing to do with a missing ffc.

Feedback needed, please reopen if error persists.

Hello, I am also having this problem as well. I am running Spyder on a Mac with Yosemite. I get the exact same error message. I tried running python -c "import ffc" and it has not fixed the problem. Can you please explain what the problem is?

[astrojuanlu]

Hello @jbcolli2, what is the error message that you see when you try python -c "import fcc"?

[jbcolli2]

Hello @Juanlu001 , There actually wasn't an error message. Executed the command in the terminal with Spyder closed. I opened Spyder and tried to run a Fenics program and got the same message as above.

I didn't quite understand, would you please try typing in a Python or IPython terminal

>>> import fcc

and paste the output?

[jbcolli2]

I have two python terminals I can use. The one I get through the Mac terminal will import ffc fine. This is because the mac terminal is set up to run Fenics. When I type in "import ffc" to the python terminal in Spyder I get the following message:

Traceback (most recent call last): File "", line 1, in ImportError: No module named 'fcc'

Do you think the problem is with Spyder not being set up correctly to find ffc? I've put the ffc path into the PYTHONPATH variable in Spyder.

Yes, it definitely looks like a misconfiguration in Spyder then. I am sorry but I cannot help with that :/ You can try printing sys.path to see if something is wrong or asking in sites like superuser.com.

Ok, thanks for your help.

I got this problem too from brew dolfin. Here's the error I got:

$ python -c "import ffc"
Traceback (most recent call last):

I get the same errors but only after I install matplotlib in the same anaconda environment as fenics. Without matplotlib, I get no error and everything works fine. Can someone help?
