dmas-at-wiris opened a new issue #13349: Cannot change grad_req in imported model
URL: https://github.com/apache/incubator-mxnet/issues/13349
 
 
   I’m trying to load a pretrained model and fine tune it. Given that I’m using batch accumulation I need to change grad_req to ‘add’. However, when i do this it crashes with the following error:
   > src/imperative/./imperative_utils.h:733: Check failed: vctx[i].dev_type != -1 (-1 vs. -1) Cannot decide context for node NoGradient
   
   This issue is also found [here](https://discuss.gluon.ai/t/topic/5766), however no solution was provided.
