pytorch terminate called after throwing an instance of ‘c10::HIPError‘

今天在跑PPO程序的时候，出现了下面的错误：

terminate called after throwing an instance of 'c10::HIPError'
  what():  HIP error: hipErrorNoDevice
HIP kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing HIP_LAUNCH_BLOCKING=1.
Exception raised from deviceCount at /pytorch/aten/src/ATen/hip/impl/HIPGuardImplMasqueradingAsCUDA.h:102 (most recent call first):
frame #0: c10::Error::Error(c10::SourceLocation, std::string) + 0x42 (0x7f839e38ec72 in /root/anaconda3/lib/python3.7/site-packages/torch/lib/libc10.so)

我的torch版本是：

torch                              1.11.0+rocm4.5.2
cuda 10.2

解决方法

回退torch版本到1.5

pip install torch==1.5

然后就可以运行了。
