I’m working on utilising a custom loss function and op, but get the following error. Has anyone recieved this before and has any idea on the potential cause?
Error in CustomOp.backward: Traceback (most recent call last):
File "/mxnet/operator.py", line 1029, in backward_entry
stype=stype))
File "/mxnet/ndarray/sparse.py", line 1185, in _ndarray_cls
raise Exception("unknown storage type: %s"%stype)
Exception: unknown storage type: -1
Thanks
