Hi, This is super impressive work. Unfortunately, I encountered an error while running the second phase(Train semi-supervised model using pretrained checkpoint) of the training code. I hope to receive assistance.

I made modifications to the “_train_loader_from_config(cfg, mapper=None, *, dataset=None, sampler=None)” in the “data/build.py”: a6b1c6a08e67d26d8292cd7e095f783

I found a few lines missing in the dataloader code, it needs to switch the sampler to a standard sampler for the unlabeled dataset. Can you check if it works after pulling the latest commit ?

Otherwise, you can set DATALOADER.SAMPLER_TRAIN = "TrainingSampler" in the config

Thank you for your answer!
