Free guidance: IndexError: The shape of the mask [0] at index 0 does not match the shape of the indexed tensor [1, 9216, 320] at index 0 #117

Line 180 here fails in stage 1 training.

https://github.com/fudan-generative-vision/champ/blob/02a9a24a9183727dcbb8eb432b46b3a19302bcb8/models/mutual_self_attention.py#L166-L186

I had to do

do_classifier_free_guidance = False

to prevent this error, however I do not know how this will impact the result.

Here is my terminal log.

The following values were not passed to `accelerate launch` and had defaults used instead:

To avoid this warning pass in values for each of the problematic parameters or run `accelerate config`.

The passed generator was created on 'cpu' even though a tensor on cuda:0 was expected. Tensors will be created on 'cpu' and then moved to cuda:0. Note that one can probably slighly speed up this function by passing a generator that was created on the cuda:0 device.

Hi @pearbender , actually you don't need to set do_classifier_free_guidance to true when training even if you want to enable CFG.

During training, the Classifier-Free Guidance works by randomly sampling conditional and unconditional input ratio as uncond_ratio: 0.1. You can modify the ratio to 0 if you wanna disable CFG training.

During inference time, set do_classifer_free_guidance=True to enable CFG. You may also find cfg_scale helpful.

@Leoooo333 Currently during stage 1 training do_classifier_free_guidance is True by default causing the error I posed to occur. If it is OK to set to false during stage 1 training then the code should be changed, right?

Hi, I have also met this error in stage 1 training, is it all well to set do_classifier_free_guidance to false during stage 1 training? @pearbender
