Request owl.elewise.pow/sqrt

[CrabTY]

Hi guys,

Is that possible for you to provide a element-wise power/sqrt function for the python interface? I'd like to adjust the weight use Adagrad or RMSprop, which requires a such operation. However, the numpy solution does not work well on multi-GPU case.
Or can you show me some instruction about how to add such operations?

Thanks.
Tao

Hi,

We will work on that. Currently it is still quite annoying to add new operators. If you wanna have a look. You could try trace the codes in:

• Register operators: https://github.com/dmlc/minerva/blob/master/minerva/op/impl/bundle.h
• Operator interface: https://github.com/dmlc/minerva/blob/master/minerva/op/impl/basic.h
• Cuda operators: https://github.com/dmlc/minerva/blob/master/minerva/op/impl/cuda.h
• Element-wise operator in NArray: https://github.com/dmlc/minerva/blob/master/minerva/narray/narray_elewise.cpp

Thanks for the feedback,
Minjie
