Description

This PR introduces PyTorch API compatibility aliases and resolves type checking issues:

1. Added PyTorch-compatible parameter aliases:

API	param1	alias1	param2	alias2
torch.nn.functional.softmax	x	input	axis	dim
torch.nonzero	x	input		out
torch.randn	shape	*size

Usage Example:

# Traditional Paddle call
output = paddle.rand([2,3])

# New PyTorch-compatible call
output = paddle.rand(2,3)
