full fisher script stability

[russellizadi]

I looked at the full_fisher numpy file and tried to change some parameters but it doesn't work. For example, when the X0 and X1 are changed as follows, the loss becomes nan after two steps:

X0 = np.random.randn(100, 2) - 2
X1 = np.random.randn(100, 2) + 2

What is the problem here? Thanks for your time.
