gautham-kollu opened a new pull request #12512: [MXNET-938] Allow fusing weight ahead of calling forward() URL: https://github.com/apache/incubator-mxnet/pull/12512 ## Description ## Issue : MXNET-938 Root Cause : _rnn_param_concat() takes a while to concat all the params. This PR allows the user to call .fuse_weights() when running Gluon with ndarray there-by preprocessing the fusing-of-weights before calling forward. Also, when running inference fusing-of-weights is not required for each batch - only once is suffice. Some of the alternative approaches are 1. Fuse Parameters() when created. 2. Fuse the weights in ".initialize()" if we are running in inference mode and if all the parameters are initialized. Sending a PR as a first-draft to get some early feedback.
