[theano-users] TypeError: can't pickle fortran objects

[Enmao Diao]

I am doing a researach project and I am able to compile and run the theano
function I created. We hope to ship a precompiled package for model
selection on Neural Network, instead of spend tons of time doing cross
validation.

Since we need to give different kinds of input to the model, and thus the
model structure is different for different input. It is a pain to compile
all possible structures each time I need them, right?
So I natrually wonder if it is possible to pickle the theano function to
the disk.
In fact, we don't train the model on theano. The parameters, data and
labels are all treated as input from other sources(trained on other
platform). Therefore, we dont have shared variable just pure symbolic
tensorvariable in the model.
The reason we need Theano is its exact gradient capability which is a
neccessary step of our algorithm.

When I try to pickle the function, it said it can't pickle fortran objects.
I guess the compiled theano function is related to fortran. I tried
the theano.misc.pkl_utils.dump but it does not work either.

I really appreciate any help on this.
