RuntimeWarning: overflow encountered in cast v.numpy().astype("float16").tofile(output_bin_file)

Got following warning when converting model

E:\Project\AiTheme\convert.py:42: RuntimeWarning: overflow encountered in cast
v.numpy().astype("float16").tofile(output_bin_file)

+1, same error on MacOS, using the runwayml/stable-diffusion-v1-5 ckpt file.

I faced the same error on Arch Linux, with Intel Core i9 10th gen CPU:

Tried this models.

• https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/v1-5-pruned-emaonly.ckpt
• https://huggingface.co/hakurei/waifu-diffusion-v1-4/blob/main/models/wd-1-3-penultimate-ucg-cont.ckpt

To avoid this error, I changed float16 type to float32 type in convert.py script like this:

v.numpy().astype("float32").tofile(output_bin_file)

After patching type in the convert.py script, all 3 models converted without issues.
