### SPLIT FOUND:  data\STARE\splits\STARE_1.json Loaded

Process finished with exit code -1
I get a lot of warnings regarding:
Mask not applied
That's probably not very good. Furthermore I get a lot of pickle errors:
_pickle.PicklingError: Can't pickle <function at 0x000002DA8D01B318>: attribute lookup on testarch.unet.runs failed
Do you know why this could be happening?
Best, Karol

No sadly not. But if you should happen to find one, than I would be glad to know :)

Hi all,
Mask not applied is not an error. It is just a warning. As for the, Can't pickle <function at 0x000002DA8D01B318>: I think I know where it is coming from. I will take a look and fix it ASAP.
As for- No such file or directory: 'logs\STARE\UNET_1_100_1\..., I think this part is for mini-unet. Which means first we need to run U-net and then mini u-net because mini-unet picks up the output of U-net as its input. This can be configured in main.py.
Sorry for the late response. Thanks, AK
