Can blip2 be run at half, or lower, precision on CPU?

Hi, when I set from_pretrained's torch_dtype=torch.float16 I get the following error back:

RuntimeError: "slow_conv2d_cpu" not implemented for 'Half'

I've seen some other instances where this error comes up when running on the CPU, which is what I'm doing in this case. Is there a way to run this model in lower precision on the CPU?
