一，从应用的层面先跑通 Harvard transformer

GitHub - harvardnlp/annotated-transformer: An annotated implementation of the Transformer paper.

​git clone https://github.com/harvardnlp/annotated-transformer.git
cd annotated-transformer/​

1. 环境搭建

 conda create --name ilustrate_transformer_env python=3.9conda activate ilustrate_transformer_envpip install -r requirements.txt  -i https://pypi.tuna.tsinghua.edu.cn/simple

问题：TypeError: issubclass() arg 1 must be a class

原因： 这是由python中的后端包之一的兼容性问题引起的问题，包“pydantic”

执行下面命令可以解决

python -m pip install -U pydantic spacy

 

会遇到下载不到数据的问题，因为有个网址废弃了：www.quest......

改成最新版本的torchtext的内容即可：

/home/hipper/anaconda3/envs/ilustrate_transformer_env/lib/python3.9/site-packages/torchtext/datasets/multi30k.py
