[英]torch.manual_seed(seed) get RuntimeError: CUDA error: device-side assert triggered
當我收到此錯誤時,我正在使用 GOOGLE COLAB。 這是我的代碼,我沒有發現任何錯誤,這些代碼幾個小時前是正確的,但突然出錯了,我不知道為什么
import torch
if torch.cuda.is_available():
device = torch.device("cuda")
print('There are %d GPU(s) available.' % torch.cuda.device_count())
print('We will use the GPU:', torch.cuda.get_device_name(0))
else:
print('No GPU available, using the CPU instead.')
device = torch.device("cpu")
seed=1
np.random.seed(seed)
torch.manual_seed(seed)
torch.cuda.manual_seed_all(seed)
torch.backends.cudnn.deterministic = True
錯誤是
There are 1 GPU(s) available.
We will use the GPU: Tesla P100-PCIE-16GB

CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
誰能幫幫我?
根據我的經驗,此錯誤可能是由於目標中的標簽數量與 model 中的類數量之間存在某種不一致而導致的。
