Install procthor Error

When I try to install procthor using `dataset = prior.load_dataset("procthor-10k")`, there is fault:
```
Traceback (most recent call last):
File "procthor.py", line 5, in
dataset = prior.load_dataset("procthor-10k")
File "/home/users/sdp/anaconda3/envs/test/lib/python3.7/site-packages/prior/__init__.py", line 302, in load_dataset
os.chdir(dataset_path)
FileNotFoundError: [Errno 2] No such file or directory: '/home/users/sdp/.prior/datasets/allenai/procthor-10k/439193522244720b86d8c81cde2e51e3a4d150cf'
```
I want to know how to solve this?
