Jupyter Notebook - How to use a data file for code

Question

this might seem like stupid question, but i don't know how to resolve this problem.

So i'm trying to integrate a code of mine that i made in ipython and make it look much much better documented. My code uses a numpy file that i made a path to use it for.

So my question is, how would i upload this numpy file to my notebook so I can use it in my .ipynb file? I tried having the .npy and .ipynb files in the same folder, but i'm clueless on how to call it.

Thank you.

Assuming you created the file with "numpy.save" then you should be able to read it with "numpy.load" if it is in the same directory.

Here's an example:

import numpy as np

x = np.array([[1,2],[3,4],[5,6]])

np.save("test", x)

y = np.load("test.npy")

print y

Sorry i'm new and a complete idiot when it comes to these things. I'm not creating a new file. I already have existing file with data i want to use.

If your "filename.npy" file is in the same directory then data = np.load("filename.npy") should load it for you. This does not work for you?

No, but that is most likely because it is not in the same directory. I'll try to fix that and see.
