Icevision models not supporting fastai learner.

[lakpa-tamang9]

I am following the same tutorial from icevision documentation here. Everything is fine until i define the leaner with fastai, the following error occurs. I have tried with other models such as yolox too, the error still perceives.

AttributeError: module 'icevision.models.mmdet.models.ssd' has no attribute 'fastai'

I can see that the fastai is imported from soft_dependencies.SoftDependencies which is triggered by the flag here.

icevision/icevision/models/mmdet/common/mask/__init__.py

Line 9 in fc19096

if SoftDependencies.fastai:

However, the flag is False in my case. I reckon, in order to import fastai learner this flag must be True. How to solve this issue?

Issue resolved by reinstalling icevision with
pip install icevision[all]. Previously, it was installed with pip install icevision. Therefore, learner packages were not installed properly.
