Hi,

I try to understand Deepdetect right now, starting with the Plattforms Docker container.
It looks great on pictures, but I have a hard time right now using it :)

My Problem: The docs seems to step over important points, like using JupyterLab. All examples shows the finished Custom masks, but how do I get them?

Is there something missing in the docs?

Example: https://www.deepdetec

Changes made in #1874 to test/models/mxnet/1rnn_layer_3lstm.json reveal an error in the fusion of a sequence of LSTM cells into a single layer RNN for gpu.

The fused result should look like:

Instead, we currently see:
![rnn_fusion_issue](https://user-images.githubusercontent.com/48

For Tizen C-API / C#-API users, emitting "error code" only is not enough.

Provide more information for each and every error with API usages, starting with ALL error cases of "invoke" in single API.
