Bidski opened a new issue #17554: Calling optimizer.create_state on block parameters throws an AttributeError URL: https://github.com/apache/incubator-mxnet/issues/17554 ## Description (A clear and concise description of what the bug is.) I am using `mxnet.optimizer.Adam` but this appears to apply to all of the optimizers. I have called `collect_params` on my block and I am passing each one to the `create_state` function of my optimizer, but this throws an `AttributeError` as shown below. ### Error Message (Paste the complete error message. Please also include stack trace by setting environment variable `DMLC_LOG_STACK_TRACE_DEPTH=10` before running your script.) ``` Traceback (most recent call last): File "./train.py", line 233, in <module> main() File "./train.py", line 159, in main generator_state = {i: generator_optimiser.create_state(i, weight) for i, weight in enumerate(generator_weights)} File "./train.py", line 159, in <dictcomp> generator_state = {i: generator_optimiser.create_state(i, weight) for i, weight in enumerate(generator_weights)} File "/usr/lib/python3.8/site-packages/mxnet/optimizer/optimizer.py", line 1202, in create_state stype = weight.stype if self.lazy_update else 'default' AttributeError: 'Parameter' object has no attribute 'stype' ``` Having a look at `mxnet/gluon/parameter.py` it seems that `context` is also an attribute that `Parameter` does not have. ## Environment ``` ----------Python Info---------- Version : 3.8.1 Compiler : GCC 9.2.0 Build : ('default', 'Jan 22 2020 06:38:00') Arch : ('64bit', 'ELF') ------------Pip Info----------- Version : 19.3 Directory : /usr/lib/python3.8/site-packages/pip ----------MXNet Info----------- Version : 1.5.1 Directory : /usr/lib/python3.8/site-packages/mxnet Num GPUs : 1 Hashtag not found.
