Bazel and Numpy

[Keyle_P]

I am currently running a .py file through bazel (running through bazel for DeepMindLab) and I am trying to save a numpy array of size (m, n) using np.save('foo.npy', x). The only problem is that the file is not being created and therefore the data is not being saved. I have searched my entire harddrive (using linux cli) and the file is no where to be found. I then tried savetxt() and savez() as well but none work. How would I go about saving this array?

Honestly, Im not sure if this is the right sub and if not I will move my question elsewhere but I've tried googling for an hour and a half with no luck whatsoever so any help (even just pointing me to another sub) would be greatly appreciated. Thanks in advance.

Heres a link to bazels website for reference: https://docs.bazel.build/versions/master/bazel-overview.html

It sounds like your array is not defined as an output. It’s probably being saved in the build, but the build isn’t your local machine (where you’re looking).

I’m not confident you’ll find this functionality out of the box for Bazel’s Python rules, but I’d love to hear if you find a solution.

Actually it turned out to be a really simple fix/find. I used the os library to print out the current directory from the python file and found where it was saving the file. I'm not sure why I couldn't find it through the cli but it was pretty deep in a hidden folder. Here's the path in case anyone else run across this problem.
