two vital errors when using this project.

[zxk19981227]

When using this project, i met two vital errors when trying to visualize the human mesh. First, the type check code. The additional command type make it impossible to input the PIL.Image. elif isinstance(im, type(Image)) and isinstance(iuv, type(Image)): im = im iuv = iuv Second, why the iuv should be multiply 255? This behaviour cause huge confusion.
