if the same code is run localy it works:

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']

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

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

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

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:

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

Validating as well

Same issue when I try to run a clone of the same program on a google colab worker:

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`

I use windows

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

🙂

it should

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()

'

' error [Errno 13] Permission denied:

Seems like a permission issue ?
Try to remove your entire clearml cache folder None

I have realy an understanding problem. I have started the process from a diffrend computer. I have deleted the complete .clearml folder.

However the training starts and the validating process fails.

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 folders are there

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
I just deleted the complet folder, still the same:

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

@<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 ?

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?

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")

...

Yes, when I understand correctly from the documentation the dataset is the first time downloaded und later on only the increment changes of it:

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

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

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

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.

However if I accses the data directly with:

there is no errormessage and the data can be accssed.

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