导入 Pytorch_Transformers 时出现模块未找到错误

Question

通过 Anaconda 下载 pytorch_transformers 并通过 Jupyter Notebook 执行导入命令后，我遇到了几个与缺少模块相关的错误。

我尝试搜索 sacremoses 通过 Anaconda 导入包，但它仅适用于 Linux 机器。还有其他人遇到过类似的问题吗？提前致谢！

from pytorch_transformers import BertTokenizer, BertModel, BertForMaskedLM

这是错误：

Answer 1

请尝试创建 conda 环境并使用以下步骤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

Answer 2

您缺少 pytorch-transformers 依赖项。尝试使用以下命令安装它：

pip install pytorch-transformers
