Hi Dr.RDevon
When I run the code cortex GAN --d.source CIFAR10 --d.copy_to_local after I setup the cortex, it still throw a error as:
[INFO:cortex]: Setting logging to INFO
Traceback (most recent call last):
File "/home/mtang4/anaconda3/envs/IARPA2/bin/cortex", line 8, in
sys.exit(run())
File "/home/mtang4/anaconda3/envs/IARPA2/lib/python3.6/site-packages/cortex/main.py", line 32, in run
config.set_config()
File "/home/mtang4/anaconda3/envs/IARPA2/lib/python3.6/site-packages/cortex/_lib/config.py", line 79, in set_config
d = yaml.load(f)
TypeError: load() missing 1 required positional argument: 'Loader'
Can you help me?
