这个错误提示的意思是，在 "/root/autodl-tmp/project/tools/../lib/net/pointnet2_msg.py" 文件的第 125 行，SelfAttention() 函数不支持 'channel_out' 这个参数。可能是版本更新或者代码改动导致的。你需要检查...

这个错误是因为在调用 forward() 函数时给了 3 个参数，但是该函数只接受 2 个参数。可能是在调用 self.SA_modules[i](l_xyz[i], l_features[i]) 时出现了问题。你可以检查一下该函数的定义，确保它只需要 2 个...

这个错误发生在 PyTorch 的一个模块中，具体来说是在 PointNet2 的消息传递层（pointnet2_msg.py）的 forward 方法中出现了问题。根据错误信息，似乎是在输入 x 时出现了问题，导致 x 变成了 NoneType，而 NoneType ...

根据错误提示的位置信息，错误出现在 pointnet2_msg.py 文件的第 154 行，在该行代码中调用了一个 SA_modules[i] 的 forward() 函数，但传入的参数数量不对。你需要检查一下调用该 forward() 函数的代码，看看...

根据错误信息，可以看出是在调用 self.SA_modules[i](l_xyz[i], l_features[i]) 时传入了三个参数，但是 forward() 方法只接受两个参数。这表明 self.SA_modules 中的某个模块在其 forward() 方法中接受了...

根据报错信息，你的 self.SA_modules[i] 的 forward 方法只接受 2 个位置参数，但是你在调用时传递了 3 个参数。所以你需要检查 SelfAttention 类的 forward 方法定义，看看它期望接收几个参数。如果你的 ...
