System information

-PaddlePaddle version 2.1.1
-CPU: including CPUMKL/OpenBlas/MKLDNN version
-GPU: not used
-OS Platform and Distribution: Mac OS 10.15
-Python version: 3.9.0
Note: You can get most of the information by running summary_env.py.

To Reproduce

See code below. Paddlepaddle doesn't handle zero-dimensional tensors (same issue as in mxnet v1, now fixed)

Describe your current behavior

Code segfaults.

[1]    71657 segmentation fault  ipython

Code to reproduce the issue

import paddle

paddle.zeros([]).transpose([]) # should return 0-dimensional tensor with 1 element, basically transpose should do nothing

paddle.zeros([]).reshape([]) # should return 0-dimensional tensor with 1 element, basically reshape should do nothing

Other info / logs

Support for zero-dimensional tensor is a hard requirement for inclusion for einops support.

Currently paddlepaddle can't pass the tests due to this issue

@arogozhnikov thanks for providing details about processing zero-dimensional tensor in transpose (reshape). We will upgrade the ability of processing zero-dimensional tensor in future. :)

Hi, @joey12300. I am also very interested in intergrade paddle to einops. paddle.zeros([]).transpose([]) seems fixed in paddlepaddle==2.2.0, but paddle.zeros([]).reshape([]) still get error:

ValueError: (InvalidArgument) The parameter 'shape' in ReshapeOp must be set. But received 'shape' is empty.
  [Hint: Expected !shape.empty() == true, but received !shape.empty():0 != true:1.] (at /paddle/paddle/fluid/operators/reshape_op.cc:135)
  [operator < reshape2 > error]
