leezu opened a new issue #18685: URL: https://github.com/apache/incubator-mxnet/issues/18685
`mx.symbol.numpy._Symbol.__deepcopy__` performs shallow copy instead of deep copy like `mx.symbol.Symbol.__deepcopy__ `. Problem: ``` [ins] In [1]: import mxnet as mx [ins] In [2]: import copy [ins] In [3]: v = mx.sym.Variable('a').as_np_ndarray() [ins] In [4]: b = copy.copy(v) [ins] In [5]: b._set_attr(name='b') [ins] In [6]: v Out[6]: <_Symbol b> [ins] In [7]: b Out[7]: <_Symbol b> ``` Expected: ``` [ins] In [1]: import mxnet as mx [ins] In [2]: import copy [ins] In [3]: v = mx.sym.Variable('a').as_np_ndarray() [ins] In [4]: b = copy.copy(v) [ins] In [5]: b._set_attr(name='b') [ins] In [6]: v Out[6]: <_Symbol a> [ins] In [7]: b Out[7]: <_Symbol b> ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
