环境搭好后运行源代码出现了以下问题：

TypeError: conv2d() received an invalid combination of arguments - got (Tensor, Tensor, padding=float, groups=int), but expected one of:
 * (Tensor input, Tensor weight, Tensor bias, tuple of ints stride, tuple of ints padding, tuple of ints dilation, int groups)
 * (Tensor input, Tensor weight, Tensor bias, tuple of ints stride, str padding, tuple of ints dilation, int groups)

根据代码意思，了解了原来在python3中的/会产生float型数值，但是cov2d要求的是int型，因此只需在ssim源包里，只需将/改成//号：然后进行运行就可以解决这个问题。
