POPPY module installation (onto Canopy)

0
votes

I'm not yet very experienced with programming. I'm trying to install this module onto Canopy and I'm having some trouble (POPPY, a physical optics simulation module). The instructions for installation (found here) tell me to do the pip install, which I do below. The error message says I need the astropy module. I have astropy installed on Canopy, but this doesn't seem to recognize that.

Do I need the astropy module to be installed elsewhere?

Here's what it says:

ME$ pip install poppy --upgrade

I'm not sure if this is related, but I also tried "pip install poppy" (without "--upgrade"). The error was a bit different, but presumably related. Here's what it gave:

Not sure if this will help, but you are using an old/early version of Canopy (1.1.0). I suggest that you update to Canopy 1.4.1 first. Either a full re-install (cleanest, see support.enthought.com/entries/23580651-Uninstalling-Canopy) or update from Canopy help menu. – Jonathan March

There's a custom in Python community to use requirements.txt file for requirements of particular package. Then do pip install -U -r requirements.txt. If that file is not there (in poppy source), you could do simply pip install astropy first to install dependency first.

However, I have to say I have had much better all-around experience with Anaconda Scientific Python distribution than with Canopy. Perhaps you should give it a try.
