How to define a variable that is not trainable?

[lightingghost]

When defining a variable in tensorflow, it is possible to set trainable=False.

Is is possible to do so in mxnet? for both symbol and ndarray APIs?

Thanks

You can use fixed_param_names paramter
See https://mxnet.incubator.apache.org/api/python/module/module.html?highlight=fixed_param_names#mxnet.module.Module

And an example.
