我在 google colab 上運行我的代碼。 我收到 RuntimeError: CUDA 錯誤：設備端斷言已觸發。錯誤顯示為 torch.manual_seed(seed)

Question

import random
total_steps = 1
seed = 42
random.seed(seed)
np.random.seed(seed)
torch.manual_seed(seed)

下面是在 () 4 random.seed(seed) 5 np.random.seed(seed) ----> 6 torch.manual_seed(seed) 7 torch.cuda 中獲取 RuntimeError Traceback (most recent call last) 的錯誤。 manual_seed_all(種子) 8 tokenizer = BertTokenizer.from_pretrained('bert-base-uncased')

RuntimeError: CUDA error: device-side assert triggered
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.

請檢查device_count()的 output。 您可以使用超出范圍的索引。
