The process feels really messy and it takes a millisecond which I feel like is pretty long for a (15, 9) numpy array. This returns a string of 1's and 0's; Then I use list() to break the string of binary into a list of single 1's and 0's; Then I convert that all to a numpy array with dtype=int numpy.unpackbits(myarray, axis=None) : This function is used to Unpacks elements of a uint8 array into a binary-valued output array.Each element of myarray represents a bit-field that should be unpacked into a binary-valued output array. Something like this: How would that conversion function look like?
