ArneNx opened a new issue #10904: switch_bucket() sets grad_req to 'write' by default and overwrites other settings
URL: https://github.com/apache/incubator-mxnet/issues/10904
 
 
   https://github.com/apache/incubator-mxnet/blob/251ae71a20d8318ab20f4c19520f74b881fdf3ff/python/mxnet/module/bucketing_module.py#L353
   
   I want to set the ``grad_req`` for all my parameters to ``'add'`` by using specifying it in the ``bind()`` call on my top-level module. 
   The problem is that I use a ``BucketingModule``. So when I call ``forward``, it automatically calls the ``switch_bucket`` method, which then calls ``bind`` again without specifying ``grad_req`` and therefore setting it to ``'write'``. 
   
   Is this intended behavior? Can I somehow work around this while still using bucketing?
