Hi
There are some problems where I run train.py and test.py

$ python train.py --training_instance model1

Loading data!
Traceback (most recent call last):
  File "train.py", line 47, in <module>
    main()

    sequence)

    num_ima_file = open(os.path.join(data_folder_path, bag_name, 'n_images.txt'), 'r')
IOError: [Errno 2] No such file or directory: '/mnt/data/mvsec/outdoor_day2/n_images.txt'

$ python test.py --training_instance ev-flownet --test_sequence outdoor_day1

There is a missing file n_images.txt.How to achieve the n_images.txt?

If you can't find it, you can just generate your own txt file. It should have two numbers separated by a space, the number of left camera images and the number of right camera images. An example is here: https://drive.google.com/file/d/1SNtu0b9jBnM3hxTEZiUnrYf80m9owjMD/view?usp=sharing
