Mmdetection: Support Evaluation over ConcatDataset

Created on 6 Jul 2020  路  1Comment  路  Source: open-mmlab/mmdetection

When combining multiple datasets for validation, evaluation function does not work.
AttributeError: 'ConcatDataset' object has no attribute 'evaluate'

Motivation
Usually you download datasets for different sources and you keep them in the same format (say COCO). You can now train with all data using concat method but it would be very useful to validate on both too.

None

Additional context

I am not sure about which would be the best approach... maybe edit ConcatDataset wrapper to merge different datasets first and then call parent class constructor.

I am willing to implement this feature myself.
