Error on example code execution

[madorin0130]

I tried to execute this sample code and got the following error (listed the last since the error is too long).
CUDA_VISIBLE_DEVICES=0 python train.py --ckpt_source ./checkpoints/source_ffhq.pt --data_path ./processed_data/sketches --exp ffhq_to_sketches
When you use the ninja or meson libary how did you use it? and If you are Ok, I want to know whether same things was happen while code implementation.

The above exception was the direct cause of the following exception:
