nlp - 导入 Pytorch_Transformers 时找不到模块错误

Question

通过 Anaconda 下载 pytorch_transformers 并通过 Jupyter Notebook 执行导入命令后，我面临几个与缺少模块相关的错误。

我尝试搜索 sacremoses 以通过 Anaconda 导入包，但它仅适用于 Linux 机器。有没有其他人遇到过类似的问题？提前致谢!
from pytorch_transformers import BertTokenizer, BertModel, BertForMaskedLM
这是错误:

请尝试使用以下步骤创建 conda 环境并在创建的环境中安装软件包:

conda create -n env_pytorch -c intel python=3.5
source activate env_pytorch
pip install pytorch-transformers
