Build: "Allocation failed - JavaScript heap out of memory"

[rwieruch]

I am using your library in my own application to feed a neural network. Thanks for your efforts!

It runs without any problems locally. But when I try to build my application with npm with mnist included, it fails to build the project.

Creating an optimized production build...

These are my current node/npm versions:

→ npm -v
5.6.0

Did you into this for your own application too?

Seems like the MNIST .json files are too large for the build step. Not sure if it is specific to my build or applies in general. In my case, I have just put the MNIST .json files outside of my build affected project and include them statically from a public folder. Maybe it helps others who run into this problem. Thanks for your library!
