When I run the following command I get a [Errno 2] error, despite using the absolute path to the directory where the ‘training _spec.json’ is located.

Is the path wrong?
Is the ‘training_spec.json’ not the file it is looking for?

The documentation at:
https://docs.nvidia.com/tao/tao-toolkit/text/image_classification.html
does not specify a name for the Spec File
Please advise

It depends on your ~/.tao_mount.json.

Make sure the ““destination”” path is available.

[peter117]

Thank you Morganh.

I have a further question but I will open a new thread.

Hi there,

I still have this same problem.

It depends on your ~/.tao_mount.json. Make sure the ““destination”” path is available.

TAO Toolkit Launcher — TAO Toolkit 3.22.05 documentation refers to ~/.tao_mounts.json and that is how I have named the file (‘mounts’, not ‘mount’)
Should I rename the file?

The path referred to in the Errno 2 is in the ~/.tao_mounts.json. and, as in post 1, the path is available.

The experiment spec is there, called 'training_spec.json.
Is this the filename that is being looked for?
TAO Toolkit Launcher — TAO Toolkit 3.22.05 documentation refers to ’ -e /workspace/tlt_drive/spec/spec.cfg

If not, what should it be named?

Hi I am still awaiting a response.

I have exactly the same issue when working with the byom Jupyter notebook

Same Errno 2 can’t find the training_spec.json

Here is the bash ‘$ ls’ showing ‘training_spec.json’ located in /home/peter/TAO_toolkit/config/files
And below is the same thing in ‘.tao_mounts.json’

Please advise

Hi,
Can you share the result of
$ cat ~/.tao_mounts.json

@pddarrell

Here is the bash ‘$ ls’ showing ‘training_spec.json’ located in /home/peter/TAO_toolkit/config/files
And below is the same thing in ‘.tao_mounts.json’

From your .tao_mounts.json, you already mount “/home/perter/TAO_toolkit” to “/workspace/tao-experiments”.
In all command such as " ! tao classification train -e spec.txt " , please note that the spec.txt should be in the path of docker. In other words, the spec.txt should be available in “destination” of the tao_mounts.josn.

@Morganh

please note that the spec.txt should be in the path of docker. In other words, the spec.txt should be available in “destination” of the tao_mounts.josn.

If I understand this correctly, I need to:

1. add another “source”: and “destination”; pair to my tao_mounts.json

2. spec.txt should be in “destination” i.e “destination”: “/home/peter/TAO_toolkit/config/files/training_spec.json”

3. What comes after “source”:

/workspace/tao-experiments/classification?

Please advise

[Morganh]

Refer to TAO Toolkit Launcher — TAO Toolkit 3.22.05 documentation.

For ease, I suggest you to set “source” and “destination” to the same.

[pddarrell]

Thank you Morganh, that did it.

Can you give me any idea why that was necessary (please)?

[Morganh]

Not necessary to be same. Just a simplest way for end users.
