Fixes #142457

Problem

slow_conv_transpose3d_shape_check currently does not enforce the constraint that the size of the weight = n_input_plane x n_output_plane x kernel_depth x kernel_height x kernel_width. This causes the undefined behavior seen in issue 142457. This can be fixed by enforcing that the sizes of weight at dims 3, 4, and 5 equals the sizes of kernel at dims 1, 2, and 3.

Fix

Added 3 TORCH_CHECKs to meet the above constraint.

Test

Reproduction code

import torch

self = torch.full((1, 2, 4, 5, 4,), 0.5, dtype=torch.double)
weight = torch.full((2, 3, 2, 3, 2,), 0.5, dtype=torch.double)
kernel_size = [1, 1, 1]
bias = torch.full((3,), 0.5, dtype=torch.double)
stride = [1, 1, 1]
padding = [2, 2, 2]
output_padding = [2, 2, 2]
dilation = [1879048192, 1879048192, 1879048192]
torch.ops.aten.slow_conv_transpose3d(self, weight, kernel_size, bias, stride, padding, output_padding, dilation)

Before fix

double free or corruption (!prev)
Aborted (core dumped)

After fix

Traceback (most recent call last):
  File "/home/system/Desktop/pytorch_contrib/pytorch/../test.py", line 11, in <module>
    torch.ops.aten.slow_conv_transpose3d(self, weight, kernel_size, bias, stride, padding, output_padding, dilation)
  File "/home/system/Desktop/pytorch_contrib/pytorch/torch/_ops.py", line 1158, in __call__
    return self._op(*args, **(kwargs or {}))
RuntimeError: Expected weight to have size 1 at dimension 3 but got 2

More verification tests

import torch

self = torch.full((1, 2, 4, 5, 4,), 0.5, dtype=torch.double)
weight = torch.full((2, 3, 2, 3, 2,), 0.5, dtype=torch.double)
kernel_size = [2, 3, 2,]
bias = torch.full((3,), 0.5, dtype=torch.double)
stride = [1, 1, 1]
padding = [2, 2, 2]
output_padding = [0, 0, 0]
dilation = [1, 1, 1]
res1  = torch.ops.aten.slow_conv_transpose3d(self, weight, kernel_size, bias, stride, padding, output_padding, dilation)
module = torch.nn.ConvTranspose3d(2, 3, kernel_size=kernel_size, stride=stride, padding=padding, output_padding=output_padding, dilation=dilation, bias=True)
module.weight = torch.nn.Parameter(weight)
module.bias = torch.nn.Parameter(bias)
res2 = module(self)
assert torch.allclose(res1, res2)
print("Success")
