ModuleNotFoundError: No module named 'mmdet.version'

Traceback (most recent call last):
File "/home/dgx/workspace/cui/ViTAE/tools/train.py", line 13, in
from mmdet.apis import set_random_seed, train_detector
File "/home/dgx/workspace/cui/ViTAE/mmdet/init.py", line 1, in
from .version import version, short_version
ModuleNotFoundError: No module named 'mmdet.version'

in the mmdet/init.py, I found the code to be written like this

from .version import version, short_version

all = ['version', 'short_version']

but the .version is not the python file, in the .version file, It is only one line of code
2.2.0

Thank you for your answer, It is true that I did not recompile the environment in this project because I compiled it in a previous project
