Intel MKL Error Parameter 4 was incorrect on entry to DGELSD.

Nothing__S — Tue, 04 Sep 2018 14:15:06 GMT

I get this error when training a neural net using using Theano and Lasagne.

In particular, I get this error when taking the square or square root of a variable e.g., theano.tensor.sqr(input)

In case it helps:

I've installed python packages: mkl 2018.0.3, mkl-service 1.1.2, mkl_fft 1.0.4, mkl_random 1.0.1

Please advise.

Hi,

Hi,

Could you please execute your entire Python reproducer with environment variable MKL_VERBOSE=1 and provide the printed verbose info for the offensive DGELSD call.

DGELSD is solving least squared problem for a general matrix `A`. The parameter 4 is likely one of the dimensions of the matrix, but the requested output will determine this definitively.

Thank you,
Oleksandr
