Cannot import PyPlot - Githubissues

This is the error I get when I run "using PyPlot". I am using Ubuntu 16.04 and had Python 2.7.12 installed. I installed anaconda hoping that would help solve the problem but it didn't. Now "python -V" gives me "Python 2.7.14 :: Anaconda, Inc."

When I run Conda.list() inside julia, I do get "matplotlib" and "basemap" (includes mpl_toolkits, I think) and when I run "conda list" outside julia (bash?) I get a longer list which also contains "matplotlib" and "basemap".

Changing the environment to the python executable outside Julia doesn't fix the problem.

sys:1: UserWarning: 
This call to matplotlib.use() has no effect because the backend has already
been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.

The backend was *originally* set to u'Qt5Agg' by the following code:
  File "/home/user/.julia/v0.6/Conda/deps/usr/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 14, in <module>
    line for line in traceback.format_stack()

WARNING: No working GUI backend found for matplotlib
ERROR: InitError: PyError (ccall(@pysym(:PyImport_ImportModule), PyPtr, (Cstring,), name)

The Python package matplotlib.pyplot could not be found by pyimport. Usually this means
that you did not install matplotlib.pyplot in the Python version being used by PyCall.

PyCall is currently configured to use the Julia-specific Python distribution
installed by the Conda.jl package.  To install the matplotlib.pyplot module, you can
use `pyimport_conda("matplotlib.pyplot", PKG)`, where PKG is the Anaconda
package the contains the module matplotlib.pyplot, or alternatively you can use the
Conda package directly (via `using Conda` followed by `Conda.add` etcetera).

Alternatively, if you want to use a different Python distribution on your
system, such as a system-wide Python (as opposed to the Julia-specific Python),
you can re-configure PyCall with that Python.   As explained in the PyCall
documentation, set ENV["PYTHON"] to the path/name of the python executable
you want to use, run Pkg.build("PyCall"), and re-launch Julia.
