Loss.backward() error after moving model from cpu to cuda


Would someone know how to help with this issue? Thanks!
If in the following code snipped, I change the device from CPU to Cuda it throws the following error:

import torch
from diffusers import AutoencoderKL

device = "cuda"

vae_2 = AutoencoderKL.from_pretrained("stabilityai/sd-vae-ft-mse", torch_dtype=torch.float32,)
classes = 2

latents = torch.randn(1, 4, 64, 64).to(torch.float32).to(device)
decoded_mask = vae_2.decode(latents, return_dict=False)[0]
target = torch.randn(decoded_mask.shape).to(device)
loss = torch.nn.MSELoss()(decoded_mask, target)

RuntimeError: CUDA error: invalid argument
CUDA kernel errors might be asynchronously reported at some other API call, so
the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

Did you solve it, please?
