*.msgpack.zst': No such file or directory #16

Closed GUT2060 closed 3 years ago

GUT2060 commented 3 years ago

Hi After running The data generation script in the datasets subfolder : ./create_data.sh , i get the following error for all sim folders generated under our_defautl_scenes : mv: cannot stat 'ours_default_data/sim*.msgpack.zst': No such file or directory
This leads to an empty valid and train folders under our_default_data . any guide line on how to solve this would be great

Thanks

running the create_physics_records.py seperatly i get the following error : sim_0001 Traceback (most recent call last): File "*****/env36/lib/python3.6/site-packages/numpy/lib/shape_base.py", line 765, in array_split Ntotal = ary.shape[axis] AttributeError: 'NoneType' object has no attribute 'shape'

During handling of the above exception, another exception occurred:

Hi @GUT2060 , can you check that you have SPlisHSPlasH 2.4.0 installed?

GUT2060 commented 3 years ago

Hi , @benjaminum , yes splishsplash 2.4 is installed i managed to solve the problem and i now have the msgpack.zst files under the our_default_data/valid and our_default_data/train folders i'm however running into another issue when running ./train_network_tf.py from the scripts folder : File "./../datasets/dataset_reader_physics.py", line 45, in iter box = data[0]['box'] IndexError: list index out of range
