Hi, I have successfully set up the environment and installed all dependencies for the Graph2Plan project.However, the download link for the pre-trained model file (checkpoints_v2.zip) provided in the README.md is returning a 404 Not Found error (http://vcc.tech/research/2020/Graph2Plan/checkpoints_v2.zip).It seems the hosting service (https://www.google.com/search?q=Ruike.com) is being discontinued, which is likely the cause of the broken link.Could you please provide an alternative download link for the checkpoints_v2.zip model file?Alternatively, if any user has this file, please consider sharing it.Thank you for your help.
