The cause may be SyncBN used in this file.
SyncBN only works with distributed environment, you may either use
tools/dist_test.sh
or modify SyncBN to BN manually during testing. https://github.com/open-mmlab/mmdetection/issues/847#issuecomment-504421173
Thanks for the clarifications, I could start the training without the error by changing it from "SyncBN" to "BN". Closing the issue.
I got this error while trying to train this model, I have also trained this and this model before without this or any errors. Anyone could help me debug it. I am using google colab by modifying this notebook. Thanks.
