but then the error occurs, after the training und the validating where succesfuly completed

It seems it is failing on the last eval ? could it be testing is missing? is it the same dataset ? can you verify the file is there? (notice I see a mix of / and \ in the file name, this is odd Windows is \ and linux/mac are / , you should never have a mix)

Hi Martin
Thank you very much for your answer and sorry for the late answer. I have testet a few things. The training works fine:

but then the error occurs, after the training und the validating where succesfuly completed

if the same code is run localy it works:

the folders are there

Validating as well

and the data.yaml file as well:

train: ../train/images
val: ../valid/images
test: ../test/images

nc: 6
names: ['S_60_aktiv', 'S_Verboten_aktiv', 'bus', 'car', 'motorcycle', 'truck']

The only difference i see is, that there is no labels.cache file in the test folder.

I use windows

Now it seems to work. I had to add the 0013_Datenset as well:

dataset_path = Dataset.get(
    dataset_name=dataset_name,
    dataset_project=dataset_project,
    alias="0013_Dataset"
).get_local_copy()
dataset_path = os.path.join(dataset_path, "0013_Datenset", "data.yaml")

The Problem where the / and . Now the process ended without any error:

🙂

@<1651395720067944448:profile|GiddyHedgehong81> just to be clear, Dataset.get_local_copy returns a path to your files,
You have to Manually add the additional path to the specific files you need to use. It does Not know that in advance.
That was the initial issue you had, and I assume it is the same one here. does that make sense ?

Hi @<1651395720067944448:profile|GiddyHedgehong81>

However I need for a yolov8 (Object detection with arround 20k jpgs and .txt files) the data.yaml file:

Just add the entire folder with your files to a dataset, then get it in your code
Add files (you can do that from CLI for example): None

clearml-data add --files my_folder_with_files

Then from code: None

data_path = Dataset.get(dataset_name="my dataset", alias="training dataset").get_local_copy()

# now all my files are in `data_path`

It worked until it should validate the trainings. Here as well the same error.

2 epochs completed in 0.174 hours.

Hi Martin

Thank you very much for your answer. I have the dataset already uploaded and it is visible by datasets. Also the dataset is downloaded and stored by .clearml. If i try to accses the data with the following code I get an Permission denied error.

If I access the dataset on the same location directly it works fine:

wait, I'm confused, how is it the datset us there? did it download the dataset?

are you saying this line for example will fail? (assuming you actually have a dataset by that name)

data_path = Dataset.get(dataset_name="002_Datenset_MASAM_for_fintuning", alias="002_Datenset_MASAM_for_fintuning").get_local_copy()

okay so it is downloaded to your machine, and unzipped , is that part correct?

If i point directly to the data.yaml the training starts without any problem

what do you mean? how do you know where the extracted file is?
basically:

data_path = Dataset.get(...).get_local_copy()

then you should be able to open your file with open(data_path + "/data.yaml", "rt")
doe that work?

with #data = r"C:\Users\junke\.clearml\cache\storage_manager\datasets\ds_30892c41582b4537bb9508f3c09ae9ed\0013_Datenset\data.yaml"

Yes this part is correct. If i point directly to the data.yaml the training starts without any problem

                          )
if __name__ == '__main__':
    main()

If i set:

#data = r"C:\Users\junke\.clearml\cache\storage_manager\datasets\ds_30892c41582b4537bb9508f3c09ae9ed\0013_Datenset\data.yaml"

the dataset (data.yaml can be accessed. I guess I do not open the dataset correctly.

try:

import os

...

dataset_path = Dataset.get(
    dataset_name=dataset_name,
    dataset_project=dataset_project,
    alias="0013_Dataset"
).get_local_copy()
dataset_path = os.path.join(dataset_path, "data.yaml")

...

Now i am wondering if this works on a google colab worker as well.

and it does 😀 .

Thank you very much

it should
