Training Time

Excuse me about how long the training cycle is?

We implement a two-stage training process. In Stage 1, we train using Objects365, and in Stage 2, we use a combination of Objects365, OpenImages, and V3Det. Each stage requires approximately 12-15 hours to complete 450,000 iterations.

Hi, @happy-hsy

1. Excuse me, do I need to download the OpenImages, and V3Det data completely? I saw that these two data sets are quite large. For example: The OpenImages data set introduction has 561GB. Do I need to download a subset of the images or do I need to download all of them. And currently I only have two cards to train with, will it take a long time to train?

Thank you for your interest. I recommend downloading all the data for training to achieve the best performance. However, if storage is a constraint, you can use a portion of the OpenImages dataset for training, though this may result in decreased performance. We have not tested this approach. Regarding training time, we have not conducted training using only two parts of the dataset, and it may require many iterations.
