Problem of liver tumor segmentation #24

Hello! First of all, thank you very much for your excellent open-source work — your tumor segmentation model has impressive performance and provides great reference value for research and applications in related fields. While using your code for liver tumor segmentation tasks, I encountered some issues and would like to seek your advice. Whether I train the model myself or use the pre-trained weights you provided, I cannot effectively segment liver tumors. Only a small portion of the tumors can be identified, and the orientation of the predicted labels for some samples is opposite to that of the original labels. I hope you can provide some solutions.Thank you.
