尝试运行一些Pytorch代码时,出现此错误:
THCudaCheck FAIL file=/pytorch/aten/src/THC/THCGeneral.cpp line=74 error=38 : no CUDA-capable device is detected
Traceback (most recent call last):
File "demo.py", line 173, in test
pca = torch.FloatTensor( np.load('../basics/U_lrw1.npy')[:,:6]).cuda()
RuntimeError: cuda runtime error (38) : no CUDA-capable device is detected at /pytorch/aten/src/THC/THCGeneral.cpp:74

我不明白您遇到问题的主要原因。但是我注意到一件事,GPU-Util 100%,而后面没有进程在运行。
您可以按照以下说明进行尝试。
在持久模式下启用。这可能会解决您的问题。 ECC与非持久性模式的结合可导致GPU 100%的利用率。
您还可以使用命令nvidia -smi -e 0
或者最好从头开始重新启动整个过程,即再次重新启动操作系统。
注意:我不确定它是否对您有用。我之前也遇到过类似的问题,所以我只是根据我的经验讲。 希望对您有帮助。
