Getting PyCharm To Use the $PATH variable

I'm new to PyCharm, so hope I haven't missed anything obvious, but I just started running some Python code, which uses Theano, and I got the following error:

     ERROR (theano.sandbox.cuda): nvcc compiler not found on $PATH. Check your nvcc installation and try again.

I don't understand why I get this error. When I use PyCharm's terminal to look for nvcc, I see

     me@ARL--M6800:~/Projects/keras-latent$ which nvcc
     /usr/local/cuda-7.0/bin/nvcc

So, it looks as though PyCharm should be able to find nvcc. Furthermore, following the advice from a similar question (https://intellij-support.jetbrains.com/hc/en-us/community/posts/206597555-PyCharm-Virtualenv-and-Environment-variables?sort_by=votes) , I explicitly added my PATH variable to PyCharm's environment (Settings->Build, Execution & Deployment -> Console -> Python Console).

From within the PyCharm terminal, I see the correct path:

     me@ARL--M6800:~/Projects/keras-latent$ echo $PATH
     /usr/local/cuda-7.0/bin:/usr/local/include:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

But, when I include the line

     print os.environ['PATH'}

in the code I'm trying to run, I see this in the run window:

     /usr/bin/python2.7 /home/me/Projects/keras-latent/data_manager_cifar100.py

(i.e. path to my interpreter and the file I'm executing). I expect that this is the source of my problem, but don't really know what to do. Any ideas would be very much appreciated.
