ok...my mistake actually ... i was told this before ... anyways...i tried running line by line and got to line #34 plt.figure()
it was executed without error but i got a python "something" in the mac dash (the icon is a circle with a helicopter rotor like something inside it)...this thing does not open when i click it i don't want to proceed with the rest of the code before knowing this is what to be expected, is it? ________________________________ From: Christopher Hogan <ho...@simpetus.com> Sent: Thursday, March 21, 2019 1:42 PM To: Saeed younis Cc: meep-discuss@ab-initio.mit.edu Subject: Re: [Meep-discuss] still having problems installing Sorry.

Here are the line-by-line instructions for getting a working Meep enviornment: You already have miniconda installed, so first ensure you have the base environment active: $ conda activate base Next, create an environment called "mp" for your meep installation. Note that this environment will be completely isolated from everything else on your system, so you don't have to worry about conflicting installations. $ conda create -n mp -c conda-forge pymeep Activate the environment (this must be done each time you open a terminal). $ conda activate mp Now your terminal prompt will have a (mp) in front of it, indicating that the "mp" environment is active. Next, as described in the documentation (https://meep.readthedocs.io/en/latest/Installation/#conda-packages) matplotlib requires an extra step on Mac. We must set the backend to TkAgg $ echo "backend: TkAgg" >> ~/.matplotlib/matplotlibrc Now we need the example scripts from the github repo. Clone the repo if you haven't already: $ git clone https://github.com/NanoComp/meep.git $ cd meep We need to ensure that the examples correspond to the same version of meep that we installed (1.8.0). $ git checkout v1.8.0 $ cd python/examples Run some examples $ python 3rd-harm-1d.py If you experience any issues, please send detailed reports of the errors.
