I change some codes using numpy to cupy because of speed.
when usingdata_class = data_A[B]["class"], It works, data type is <class 'numpy.ndarray'>, and Data is ['N' 'N' 'N' ... 'N' 'N' 'N']
But, When I change to cupy.array to using GPU, It occur ValueError: Unsupported dtype <U1
I changed like this...
data_class = cp.array(data_A[B]["class"])
or
data_class = cp.array(data_A[B]["class"],dtype='unicode')
but it also have ValueError.
How can I change <class 'numpy.ndarray'> to <class 'cupy.array'>?
Thank you.
