 ## Quick Start
 
 1. download GPT2 pre-trained model in Pytorch which huggingface/pytorch-pretrained-BERT already made! (Thanks for sharing! it's help my problem transferring tensorflow(ckpt) file to Pytorch Model!)
-
 ```shell
 $ git clone https://github.com/graykode/gpt-2-Pytorch && cd gpt-2-Pytorch
 # download huggingface's pytorch model 
 $ curl --output gpt2-pytorch_model.bin https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-pytorch_model.bin
 # setup requirements
-$ python3 -m venv venv
-$ source venv/bin/activate
