tao classification train -e ./specs/classification_spec.cfg -r ./ -k xxxx

Terminal command execution error
FileNotFoundError: [Errno 2] No such file or directory: ‘./specs/classification_spec.cfg’

jupyter command error

I am sure that my configuration file path and training set path are okay, but it always prompts that various files cannot be found

train_dataset_path: “/home/ncp/tao/cv_samples_v1.2.0/classification/faces/train”
val_dataset_path: “/home/ncp/tao/cv_samples_v1.2.0/classification/faces/val”
pretrained_model_path: “/home/ncp/tao/cv_samples_v1.2.0/classification/resnet_18.hdf5”

Please note that all the path in your command is the path inside the docker.
So, you need to set the path according to your ~/.tao_mounts.json.
tao classification train -e <the path you set in destination> -r ./ -k xxxx

My ~/.tao_mounts.json path settings are the same, they are all absolute paths, but I didn’t find any problems.

Please modify above to

tao classification train -e /home/ncp/tao/cv_samples_v1.2.0/classification/specs/classification_spec.cfg -r ./ -k xxxx

I tried this, but it didn’t work, and the same error was displayed.

I suggest you to modify your tao_mounts.json.
Only keep the 2nd “source and destination” .

“source” : “/home/ncp/tao/cv_samples_v1.2.0/classfication”,
“destination” : “/home/ncp/tao/cv_samples_v1.2.0/classfication”

You mean, just keep one setting, right? , It’s better I just keep the second one.
So may I run in the terminal or jupyter?

Yes, I am afraid 1st setting conflicts with 2nd setting. So just keep 2nd.

Try terminal firstly.

ok thanks,I will test it at night
But I still have a question about this setting. For example, what is the path written after the -r parameter for? Is it the default weight file or the training data?

It is the result folder. Usually it stores the tlt file which is generated during training.

I tested it, and this time it prompts that the training file cannot be found?
FileNotFoundError: [Errno 2] No such file or directory:’/home/ncp/tao/cv_samples_v1.2.0/classification/faces/train’

Please check all the path in your training spec file.

For above error, actually you can check the file with below command.
$ tao classification run ls /home/ncp/tao/cv_samples_v1.2.0/classification/faces/train

I suggest you to login into the docker to debug any issue.
$ tao classification run /bin/bash


Yes, currently you already login the docker.
You can check whether a file is available.
Or you can run training,etc.
$ classification train xxx

classification train -e /home/ncp/tao/cv_samples_v1.2.0/classification/specs/classification_spec.cfg -r ./ -k nvidia_tlt error

FileNotFoundError: [Errno 2] No such file or directory: ‘/home/ncp/tao/cv_samples_v1.2.0/classification/faces/val’

I doubt whether it is necessary to set the verification file and test file path in tao.json?

No, see TAO Toolkit Launcher — TAO Toolkit 3.0 documentation, tao_mounts.json is used to map local folder to docker.

I have no name!@16d3728c815e:/workspace$ train -e
bash: train: command not found

Please use
$ classification train xxx xxx
