python - VersionConflict in fastprogress

Question

Please, I'm using Google Colab and Python3

I have a problem with VersionConflict in fastprogress. I have this code:

!curl -s https://course.fast.ai/setup/colab | bash
import warnings
warnings.filterwarnings('ignore')
from fastai.vision import *
from fastai.metrics import error_rate
import fastai
print(f'fastai: {fastai.__version__}')
print(f'cuda: {torch.cuda.is_available()}')


---------------------------------------------------------------------------
VersionConflict                           Traceback (most recent call last)
<ipython-input-17-01736c3668f8> in <module>()
      1 import warnings
      2 warnings.filterwarnings('ignore')
----> 3 from fastai.vision import *
      4 from fastai.metrics import error_rate
      5 import fastai

    789                 # Oops, the "best" so far conflicts with a dependency
    790                 dependent_req = required_by[req]
--> 791                 raise VersionConflict(dist, req).with_context(dependent_req)
    792 
    793             # push the new requirements onto the stack

VersionConflict: (fastprogress 0.1.22 (/usr/local/lib/python3.6/dist-packages), Requirement.parse('fastprogress>=0.2.1'))

I have also tried updating with (!pip install --upgrade fastprogress) but the message is already updated

Requirement already up-to-date: fastprogress in /usr/local/lib/python3.6/dist-packages (0.2.1)

Does anyone know the reason?

我刚才也面临同样的问题。就我而言，奇怪的是，我可以在重新启动内核后成功导入。
