But I run eval_sem_seg.py, the miou is not 0 but 69. How can I solve it? Thanks.

The pseudo labels are assigned with their class indexes ranging from 0 to 20 (for VOC dataset) so they look all black. You can convert them to color maps with some palette tools as follows. https://github.com/chenqi1126/SIPE/blob/66513a2a33d563434dd7ba7b80e8071b58c94cb4/make_seg_labels.py#L59-L61
