troubleshooting:

I have installed numpy using pip

I have uninstalled numpy then reinstalled it

[vorticalbox]

pip install bumpy.

Did you create a virtual environment (venv)? If you did, you need to activate the virtual environment through the terminal and then run pip.

No I'm running this on my normal enviroment

that didn't work

[jincio]

he misspell it its: "pip install numpy"

You might have installed it for Python 2. Try "pip3 install numpy".

Phone auto corrected it, thanks for clearing up.

Yeah it's pip3 unless you're in virtual or changed some settings somewhere.

That did not work

You may have multiple versions of python installed and pip is installing to a different version than "py" is using.

 

In the command prompt run:

where py

If you can also provide the output of:

path

then we can see if the location that pip is installing numpy (in your appdata) is in your path.

Ok, I think the issue is that you have two versions of python installed, one in c:\Windows and one in c:\Users\porte\AppData\... Numpy is being installed to the version in  c:\Users\porte\AppData\... but when you run python you are calling the installation in c:\Windows

 

Could you try running:

C:\Users\porte\AppData\Local\Programs\Python36-32\python.exe 2layerNeuralNetwork.py

Hopefully this should run using the version of python that has numpy installed.

 

 

 

For a better/longer term solution, I would suggest setting up a virtual environment (https://virtualenv.pypa.io/en/stable/userguide/) and using that for running python scripts on windows. There is a simple tutorial here: http://programwithus.com/learn-to-code/Pip-and-virtualenv-on-Windows/ or many more a google search away.
