torch.Tensor(array)时，报错:ValueError: At least one stride in the given numpy array is negative, and tensors with negative strides are not currently supported. (You can probably work around this by making a copy of your array with array.copy().)
原因分析：
主要原因是Nunmpy中，随机初始化的数组默认都是C连续的，经过slice操作后，其连续性被改变，需要’numpy.ascontinguousarray(array)'，使内存不连续的array转换为内存连续存储的数组。
