Hello, thanks for your impressive work! However, I am not able to reproduce the results of Cityscapes using this repo. In the paper, the mIOU of HRNetv2 increased to 81.4, and the mIOU of HRNetv2+OCR increased to 83.2 on the Cityscapes dataset. When I ran the script "run_h_48_d_4_contrast_mem.sh", the mIOU is hard to converge. Also I notice that the script of HRNet+OCR+Contrastive based on memory bank is not given, could you suggest me how to achieve the experimental results in the paper?
