JulianSlzr opened a new pull request #8956: Fix __repr__ for gluon.Parameter URL: https://github.com/apache/incubator-mxnet/pull/8956 ## Description ## Printing `gluon.Parameter` (`__repr__`) gives an error; this resolves the issue. ## Checklist ## ### Essentials ### - [x] Passed code style checking (`make lint`) - [x] Changes are complete (i.e. I finished coding on this PR) - [n/a] All changes have test coverage - [n/a] For user-facing API changes, API doc string has been updated. For new C++ functions in header files, their functionalities and arguments are well-documented. - [x] To my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change ### Changes ### - [x] Update `gluon.Parameter.__repr__` ## Comments ## Printing any `gluon.parameters` (e.g., `print(net.collect_params())`) will give: ``` .../site-packages/mxnet/gluon/parameter.py", line 120, in __repr__ return s.format(**self.__dict__) KeyError: 'shape' ``` instead of ``` model0_ ( ... Parameter model0_dense1_weight (shape=(10, 0), dtype=<class 'numpy.float32'>) Parameter model0_dense1_bias (shape=(10,), dtype=<class 'numpy.float32'>) ) ``` This regression in 1.0.0 due to [this change](https://github.com/apache/incubator-mxnet/commit/1852e2f47d68bb4c2373a359a2a8671b59cd14e5#diff-89ace34cda0f147e8dd6010b0a19be90R110), though `__repr__` was also at fault for using `self.__dict__` directly instead of the properties.
