使用Colab运行pytorch文件

#numpy报错改这行return self.cpu().detach().numpy()
#1. 查看pytorch版本：
import torch
print(torch.__version__)
#2.查看cuda版本：
print(torch.version.cuda)

#看gpu
!/opt/bin/nvidia-smi
#挂硬盘
from google.colab import drive
drive.mount('/content/drive/')
#重启
import os
os.kill(os.getpid(), 9)

#!pip install torch==1.10.2 torchvision==0.11.3 -f https://download.pytorch.org/whl/torch_stable.html
!pip install transformers==3.4.0
!pip install numpy==1.19
!pip install matplotlib==2.2.4


%run "/content/drive/MyDrive/model/nlp/bert_model.py"
#或者
!python "/content/drive/MyDrive/model/nlp/bert_model.py"
#画图
import matplotlib.pyplot as plt
