Can you simply delete the directory from your python installation, or are there any lingering files that you must delete?
ERROR: flake8 3.7.9 has requirement pycodestyle<2.6.0,>=2.5.0, but you'll have pycodestyle 2.3.1 which is incompatible.
ERROR: nuscenes-devkit 1.0.8 has requirement motmetrics<=1.1.3, but you'll have motmetrics 1.2.0 which is incompatible.

Attempting uninstall: torch
Found existing installation: torch 1.0.0
Uninstalling torch-1.0.0:
Successfully uninstalled torch-1.0.0
Attempting uninstall: torchvision
Found existing installation: torchvision 0.2.1
Uninstalling torchvision-0.2.1:
Successfully uninstalled torchvision-0.2.1
Attempting uninstall: entrypoints
Found existing installation: entrypoints 0.2.3
ERROR: Cannot uninstall 'entrypoints'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Then I type:
conda uninstall entrypoints
pip install --upgrade pycodestyle
pip install nuscenes-devkit
Done!
