Sorry for being a bit inaccurate.
My Scala code actually mirrors the NumPy based random initialization, so I
sample with Gaussian of mean = 0 and std dev = 1, then multiply with 0.01.
Despite the extra step the result should be the same as with the NumPy code
above.

Is there anything else that could be different with the random
initilization methods?
