运行demo.py会出现错误 #166

Closed Richard149 closed 3 years ago

Hi,感谢你们这么棒的工作，我在运行test.py没有问题，但是运行demo.py会出现： RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.FloatTensor [324, 3, 3]], which is output 0 of ViewBackward, is at version 37; expected version 35 instead. Hint: enable anomaly detection to find the operation that failed to compute its gradient, with torch.autograd.set_detect_anomaly(True) 请问这是因为IK的关系才会出现这样的错误吗？

Hi, 能提供一下更具体的报错信息吗，譬如行号以及调用栈等

感谢您的及时回复，出错的信息如下 报错信息 错误位置是这个函数 fix_foot_contact() 我将这个函数注释掉就可以正常运行了
