Error while evalute kitti dataset

[XinyuMeng]

I am getting error while evalute kitti dataset. The error message is as follows：

File "evaluate.py", line 204, in
validate_kitti(model.module)
File "/home/mxy/anaconda3/envs/pytorch_gpu/lib/python3.7/site-packages/torch/autograd/grad_mode.py", line 27, in decorate_context
return func(*args, **kwargs)
File "evaluate.py", line 154, in validate_kitti
flow_low, flow_pr = model(image1, image2, iters=iters, test_mode=True)
ValueError: too many values to unpack (expected 2)

I put the datasets in this folder : /home/mxy/CODES/RAFT/datasets/KITTI ,it is organized as below:
├── KITTI
├── testing
├── training
├── devkit
and I read the image data correctly.
