Possibly incorrect import path for `app`

[roastduck]

Hi team,

I am trying to run the example training script for MatrixCity by:

python app/trainer.py --config confs/matrixcity/matrixcity_2block_multi.txt

It reports the following error:

Traceback (most recent call last):
  File "/home/rd/src/LandMark_experiments/LandMark/app/trainer.py", line 11, in <module>
    from tools.render_utils import evaluation, evaluation_static, renderer_fn

ModuleNotFoundError: No module named 'app'

Apparently app should not be the name of a installed package. Running with PYTHONPATH=.:$PYTHONPATH works around the problem, but maybe app should be imported by .app or from other reliable paths.

Thanks for your suggestion. Our current approach is to introduce the following environment variables:

export PYTHONPATH=$YOUR_DIR/landmark/app:$PYTHONPATH
