Issue encountered during training!

[MushfiqPlabon]

This one came when I tried to train it:

C:\Users\rahma\Downloads\raisr-master\hashkey.py:40: RuntimeWarning: invalid value encountered in sqrt
sqrtlamda2 = np.sqrt(w[1])

This one came when I finished training:

C:\Users\rahma\AppData\Local\Programs\Python\Python37\lib\site-packages\numpy\linalg\linalg.py:2093: RuntimeWarning: overflow encountered in det
r = _umath_linalg.det(a, signature=signature)

This came when I tried to retrain (I tried to train using a RAW file, I think you can't use RAW files):

C:\Users\rahma\AppData\Local\Programs\Python\Python37\lib\site-packages\numpy\linalg\linalg.py:2093: RuntimeWarning: overflow encountered in det
r = _umath_linalg.det(a, signature=signature)
