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import命令后，我遇到了一些与缺少模块有关的错误。

我尝试搜索sacremoses，以通过Anaconda导入软件包，但是它仅适用于Linux计算机。还有其他人遇到过类似的问题吗？预先感谢！

from pytorch_transformers import BertTokenizer, BertModel, BertForMaskedLM

这是错误：

Answer 1

请尝试创建一个conda环境，并使用以下步骤在所创建的环境中安装软件包：

1. conda create -n env_pytorch -c intel python = 3.5
2. 源激活env_pytorch
3. pip安装pytorch-transformers

希望这会有所帮助。

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
