You have to change the gpu ids in base options.
I was selecting '2,3', ( I have 4 gpus.).
You should have fewer GPUs available. Write '0,1' if you have 2 GPUs available
from 3d-cyclegan-pytorch-medimaging.
Sorry,
I take a "--gpu_ids '0,1'"
the following comment appears and train.py does not work.

Do you know of a better way?
from 3d-cyclegan-pytorch-medimaging.
I was mistaken.
Training is now working after changing parameters.
--gpu_ids 0, --patch_size 64,64,32
However, I get the following message and test.py is not running.

Traceback (most recent call last):

IndexError: index 1 is out of bounds for dimension 0 with size 1
Which parameters should I change?
Please let me know. Thank you very much for your help.

hello
Thanks for sharing the code
I want to run on cpu
and I set gpu_ids
to -1
:
python .\train.py --gpu_ids -1
but I have the following error:
Traceback (most recent call last):
File ".\train.py", line 15, in <module>
opt = TrainOptions().parse()
