Can I install nupic under Windows Subsystem for Linux?

In Windows 10 64-bit I have enabled Windows Subsystem for Linux, which gives me Bash on Ubuntu 14.04 LTS on Windows.

Can I install nupic under this subsystem?

I don’t know. Try it out and let us know!

Make sure the environment has these dependencies installed.

Once I created a virtualenv (and then installed required dependencies) things went smoothly so it seems like pip install nupic installed without error.

Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import nupic
>>>

Is there something else I can do to test the installation?

Can you try running the simple hotgym example without swarming?

> cd examples/opf/clients/hotgym/simple
> python hotgym.py

If you get output like this, NuPIC is probably installed properly.

Thought I was close. Any idea?

$ python hotgym.py

If you want to check the installation without the repository handy, you can execute the following command line tool that gets installed by nupic.bindings (which is a dependency of nupic):

nupic-bindings-check

That will be installed in the bin directory inside the prefix you used to install the package so the bin path must be part of your PATH environment variable. If you need help with this then post the result of this:

python -c "import nupic; print nupic.__file__"
9

That doesn’t look good - looks like it could be a Windows-specific issue.

You could try installing capnp manually:

curl -O https://capnproto.org/capnproto-c++-0.5.3.1.tar.gz
tar zxf capnproto-c++-0.5.3.1.tar.gz
cd capnproto-c++-0.5.3.1
./configure
make -j6 check
sudo make install
11

Seems to compile ok but then looks like Test suite fails. So I guess it’s an issue with Capn Proto and WSL (Windows Subsystem for Linux)

Between https://github.com/numenta/nupic/blob/master/appveyor.yml and https://github.com/numenta/nupic/blob/master/ci/appveyor/install_python_pip.ps1, which we use for windows CI builds there may be enough details to get it up and running on Windows on your own, independent of the Ubuntu Linux subsystem. There are equivalent files in nupic.core for building it from source.
