安装 numpy

安装numpy的话参考下边的链接即可(亲测有效)：

Linux下安装numpy_abc_321a的博客-CSDN博客_linux安装numpy

或者用pip 安装

pip install numpy

常见问题：

(1)  numpy版本不正确，所以报错。

Traceback (most recent call last):
  File "run_disamb.py", line 471, in <module>
    main()
  File "run_disamb.py", line 414, in main
    global_step, tr_loss = train(args, train_dataset, model, tokenizer)
  File "run_disamb.py", line 205, in train
    results = evaluate(args, model, tokenizer)
  File "run_disamb.py", line 280, in evaluate
    all_pred_indexes = torch.cat(all_pred_indexes).numpy()
RuntimeError: Numpy is not available

 解决方案： 先用pip卸载numpy，然后再装版本稍微高一点的numpy。比如我的是先从1.19.0 版本升到 1. 20.0版本 ，结果还是不行， 后来升到 1.22.3 版本就可以了。

$ pip uninstall numpy

$ pip install numpy==1.22.3 -i https://pypi.douban.com/simple/

 (2)  由于下载源是国外的，一直报错超时。

 解决方法：换一个源下载numpy。(我这里是在曙光平台上下载的，如果有小伙伴从这个源下载失败的话，可以再找个合适的源试试)

$ pip install numpy==1.20 -i https://pypi.douban.com/simple/

 

安装 nltk

pip install nltk

安装 torch 

从下边链接中选个合适的版本 

Previous PyTorch Versions | PyTorch

也可以从此链接中下载：

https://download.pytorch.org/whl/torch_stable.html

注：我的cuda 是 10.1 ，选的torch 版本是1.5.0，所以命令行是：

pip install torch==1.5.0+cu101 torchvision==0.6.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

​

 安装 transformers

pip install  transformers
