Environment.yml is broken

[eugenevinitsky]

Numpy=1.13.0 leads to some crazy looking error. This is extremely high priority, I will confirm that it passes on my machine and @AboudyKreidieh can you try it on your machine and confirm this works?

[AboudyKreidieh]

I got this

UnsatisfiableError: The following specifications were found to be in conflict:
  - matplotlib==2.0.2
  - numpy==1.14.0
  - python==3.5.2
Use "conda info <package>" to see the dependencies for each package.

[AboudyKreidieh]

do we really need to fix the numpy version? I feel like this is the one package that we can rely on for being stable. open to opinions though

[eugenevinitsky]

The numpy versions can conflict with tensorflow versions.

[eugenevinitsky]

We do have to fix it though, if you install the current version set of requirements you immediately get an error.

[eugenevinitsky]

You get that error running which command?

[AboudyKreidieh]

I see, does tensorflow specify a dependency?

[AboudyKreidieh]

running conda create env

[eugenevinitsky]

Trying to find it.

[AboudyKreidieh]

try running the setup instructions on an ubuntu 16.04 machine on aws

[eugenevinitsky]

Ostensibly it's tensorflow==1.10.0 [requires: numpy>=1.13.3,<=1.14.5]
but if you try and import tensorflow with numpy==1.13.3 you get

RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
ImportError: numpy.core.multiarray failed to import
ImportError: numpy.core.umath failed to import

[eugenevinitsky]

kk, testing ubuntu 16.04

[eugenevinitsky]

Oof yeah you get:

NoPackagesFoundError: Package missing in current linux-64 channels:

• numpy ==1.14.0
  for conda 4.3.8

[eugenevinitsky]

...how did this ever work?!

[eugenevinitsky]

Confirmed on three machines (@kanaadp @lucfisc and mine) that this works on OSX

[eugenevinitsky]

Confirmed that this works on a 16.04 machine @AboudyKreidieh

[eugenevinitsky]

No luck on a 14.04 machine.

LGTM! thanks for doing this
