spiralpp:zipfile.BadZipFile:文件不是zip文件

Question

我正在尝试运行urw7rs/spiralpp，这是一个深入学习的项目

首先，我通过以下命令安装了他们的docker映像：

docker run -it -p 8888:8888 urw7rs/spiralpp:latest /bin/bash

下面是Docker映像内部的ls输出：

(spiralpp) root@8c0404e74c57:/src/spiralpp# ls
CODE_OF_CONDUCT.md  
LICENSE    
dataset.lock   
libtorchbeast.egg-info  
pyproject.toml    
setup.py     
third_party

README.md  
demo.ipynb     
nest                    
requirements.txt

Dockerfile          
build      
libtorchbeast  
plot.ipynb              
scripts           
tests

然后在运行此命令后：

python -m torchbeast.polybeast \
     --dataset celeba-hq \
     --env_type libmypaint \
     --canvas_width 64 \
     --use_pressure \
     --use_tca \
     --num_actors 64 \
     --total_steps 30000000 \
     --policy_learning_rate 0.0004 \
     --entropy_cost 0.01 \
     --batch_size 64 \
     --episode_length 40 \
     --xpid example

我得到了以下错误：

Traceback (most recent call last):

    raise BadZipFile("File is not a zip file")
zipfile.BadZipFile: File is not a zip file

错误来自第122行/src/spiralpp/torchbeast/core/datasets.py：

with zipfile.ZipFile(
            os.path.join(self.root, self.base_folder, "CelebAMask-HQ.zip"), "r"
        ) as f:
            f.extractall(os.path.join(self.root, self.base_folder))

下面是来自CelebAMask-HQ目录内的ls的输出：

(spiralpp) root@8c0404e74c57:/src/spiralpp/CelebAMask-HQ# ls
CelebAMask-HQ.zip
