FileNotFoundError: File /ml3d/configs/randlanet_semantickitti.yml not found

[Ed0flower93]

Hi, I am trying to use open3d and I can open the "reading datasets" correctly. But when I try the "loading config file" I get this error:

Traceback (most recent call last): File "/home/edoardo/Documenti/Open3D_documents/Loading_config_file.py", line 6, in cfg = _ml3d.utils.Config.load_from_file(cfg_file) File "/home/edoardo/.local/lib/python3.6/site-packages/open3d/_ml3d/utils/config.py", line 212, in load_from_file raise FileNotFoundError(f'File {filename} not found') FileNotFoundError: File /ml3d/configs/randlanet_semantickitti.yml not found

I've tried changing the path but I can't figure out where the error is. I hope for your help.

Thanks

@Ed0flower93 the path you've given starts with / (root), which is invalid. Could you recheck the path or post the exact script you are using?

[Ed0flower93]

Sure, This is my script and I simply change the dataset root. I also try to put the absolute path from the terminal but i got the same error. This is my script:

import open3d.ml as _ml3d import open3d.ml.torch as ml3d # or open3d.ml.tf as ml3d

framework = "torch" # or tf cfg_file = "ml3d/configs/randlanet_semantickitti.yml" cfg = _ml3d.utils.Config.load_from_file(cfg_file)

fetch the classes by the name

Pipeline = _ml3d.utils.get_module("pipeline", cfg.pipeline.name, framework) Model = _ml3d.utils.get_module("model", cfg.model.name, framework) Dataset = _ml3d.utils.get_module("dataset", cfg.dataset.name)

use the arguments in the config file to construct the instances

cfg.dataset['dataset_path'] = "/media/edoardo/LaCie/data_odometry_velodyne" dataset = Dataset(cfg.dataset.pop('dataset_path', None), cfg.dataset) model = Model(cfg.model) pipeline = Pipeline(model, dataset, **cfg.pipeline)

Is ml3d/configs/randlanet_semantickitti.yml the correct relative path to that config file? To sanity check it is, you ought to be able to run ls ml3d/configs/randlanet_semantickitti.yml from within the same folder as your script and have it successfully find the file.

I suspect your custom script is sitting inside another folder and ml3d/configs/randlanet_semantickitti.yml is not the correct relative path to that config file.

Thank you very much, now it works. I have also another problem with the semantic segmentation script:

import os import open3d._ml3d as _ml3d import open3d.ml3d.torch as ml3d

cfg_file = "ml3d/configs/randlanet_semantickitti.yml" cfg = _ml3d.utils.Config.load_from_file(cfg_file)

model = ml3d.models.RandLANet(cfg.model) cfg.dataset['dataset_path'] = "media/edoardo/LaCie/data_odometry_velodyne" dataset = ml3d.datasets.SemanticKITTI(cfg.dataset.pop('dataset_path', None), cfg.dataset) pipeline = ml3d.pipelines.SemanticSegmentation(model, dataset=dataset, device="gpu", **cfg.pipeline)

The error is the following one:

Traceback (most recent call last): File "/home/edoardo/.local/lib/python3.6/site-packages/open3d/Semantic_segmentation.py", line 10, in dataset = ml3d.datasets.SemanticKITTI(cfg.dataset.pop('dataset_path', None), **cfg.dataset) AttributeError: module 'open3d.ml3d.torch' has no attribute 'datasets'

I already tried to add the dataset foldet to the torch folder but it is still there.

Thanks again for your support

[kylevedder]

It should be import open3d.ml.torch as ml3d.

As a test of this, I was able to run the following script

python -c "import open3d.ml.torch as ml3d; foo = ml3d.datasets.SemanticKITTI; print(foo)"

which printed

<class 'ml3d.datasets.semantickitti.SemanticKITTI'>

[Ed0flower93]

Thanks a lot for your support, I did the correction and the test was completed correctly as you suggested, but the script show me another error, maybe caused from the datasets:

I don't know why on the folder 11 and not in the first folder. I have no idea. Thank you again

[kylevedder]

This is the root cause:

FileNotFoundError: [Errno 2] File o directory non esistente: 'media/edoardo/LaCie/data_odometry_velodyne/dataset/sequences/11/velodyne'

Your path needs to be an absolute path to the /media directory but you don't have the preceding /; it should be /media/edoardo/LaCie/data_odometry_velodyne/dataset/sequences/11/velodyne

Two of the errors you have written about in this thread have stemmed from incorrect relative or absolute file paths. I suggest that you read up on how relative and absolute file paths work so that you don't need to ask other people how to fix these "file not found" issues.

[Ed0flower93]

You're right, so I'll only bother you for important things. One last thing, is it possible to acquire and create your own datasets with a depth camera such as the intel realsense d435?

Thank you very much

[kylevedder]

Yes, see ml3d/datasets/customdataset.py in this repo for details.
