Error is caused when using test data

[JaeWangL]

I just typed "s2p tests/data/input_pair/config.json" in terminal But below error is showed How can I fix this?

tile size: 350 350
total number of tiles: 4 (2 x 2)

discarding masked tiles...

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

In "is_this_tile_useful" in s2p/initialization.py I printed config for checking my settings like following

print(cfg['images'])
rpc = cfg['images'][0]['rpcm']

But cfg doens't contains my values. So, rpc has no value Is it normal??

In Addition, in "tiles_full_info", cfg has my own values

My environment is Python 3.8 with anaconda3 on MacOS

@JaeWangL, did you figure out this issue?
