Issue
I am trying to normalize a CSR matrix,
but I get this error: (*** TypeError: No matching signature found).
from sklearn.preprocessing import normalize
normalize(x_m, norm="l2", axis=1)
The matrix is 609186x849632 sparse matrix of type 'numpy.float16' with 189140200 stored elements in Compressed Sparse Row format
Solution
Actually I solved the problem. I think it is because of the data type. Changing np.float16
to np.float32
, solved the problem. I do not know why, this problem only happens with np.float16
data type.
