Single-card inference

[1099255210]

After training on server, I got DS-GAN-Epoch300.pth, I wanted to use this weight for single-card inference.

I changed device_ids = [0, 1, 2, 3] to device_ids = [0], and ran infer.py, then I got this error:

RuntimeError: Expected hidden[0] size (8, 4, 256), got [8, 1, 256]

Would you please try this, or offer some tips and instructions on single-card inference? Thank you!

Setting test_batch_size to 1 solved my problem.
