Neu.ro provides storage to host files that are required to run your jobs. All users on a platform can access the platform storage to manage data, code, and artifacts. Each storage is specific to that cluster, and you cannot reuse files between clusters. You can manage your storage either from the Web UI or the CLI.
The following image shows an overview of data flows between your local machine, the storage, and the job file system:
You can use the intuitive FileBrowser tool available in Neu.ro to manage files in storage. The FileBrowser is based on the popular file browsing interface available on git.
To manage files:
Login into Neu.ro.
Click on Start FileBrowser.
This opens the file browser for the cluster, where you can host and manage files.
The file browser has the following areas:
Toolbar: Lets you search for files, download, and upload files. It also provides various other context-based options that are available depending on the file or folder you select.
Options: Lets you create a new folder or file. It also lets you manage the storage settings.
Folders and Files: Lists the folders and files you have access to. You can select files to view context-based options in the toolbar.
The rest of this tutorial will describe managing your files using the CLI. For more information about FileBrowser, see the FileBrowser documentation.
You can manage your files and folders using the neuro storage command. The neu.ro CLI lets you perform all operations with your files and folders that are available from the FileBrowser.
To view the folders and files in an image, use the command:
neuro ls [OPTIONS] PATHS
For more information, see List directory contents.
> neuro storage ls storage:nero-assistantModelCode apt.txt config data modulesnotebooks requirements.txt results setup.cfg
You could use
neuro storage tree to view the contents in a tree format. This is recommended when you have multiple sub-folders.
> neuro storage tree storage:nero-assistant'storage:nero-assistant'+-- 'ModelCode'| +-- 'VoiceExperiment'+-- 'apt.txt'+-- 'config'+-- 'data'+-- 'modules'+-- 'notebooks'+-- 'requirements.txt'+-- 'results'+-- 'setup.cfg'7 directories, 3 files
You can create folders in the storage from the CLI by using the command:
neuro storage mkdir [OPTIONS] PATHS
This works the same way as the web UI, but, in CLI, you can create folders in any path without having to navigate to that path.
neuro storage mkdir -p storage:nero-assistant/ModelCode/VoiceExperiment
The folder is created and you can verify by running the
neuro storage ls command or in the Web UI.
You can use the
neuro cp SOURCE DESTINATION command to move files between the storage and the host machine.
For moving folders, you must use the recursive copy command so that the folder contents are also moved:
neuro cp -r SOURCE DESTINATION.
Remember the following key points before moving files or folders to and from storage:
The command assumes that the path provided is relative.
File and folder names are case-sensitive.
To move files from local machine to storage, use the command
neuro cp parameters.txt storage:nero-assistant
This command copies the file
parameters.txt from the local host machine to the storage folder
> neuro cp parameters.txt storage:nero-assistantCopy 'file:///C:/Projects/parameters.txt' => 'storage://neuro-public/.../parameters.txt' 'parameters.txt' 952B
To move files from storage to the local machine, use the command
neuro cp storage:nero-assistant/TestResults.txt file:///Projects
This command copies the
TestResults.txt file from the storage folder
nero-assistant to the local host machine.
> neuro cp storage:nero-assistant/TestResults.txt file:///ProjectsCopy 'storage://neuro-public/.../TestResults.txt' => 'file:///C:/Projects/TestResults.txt' 'TestResults.txt' 1.5K
To move folder from local host system to storage, use the command
neuro cp -r samplecode storage:nero-assistant
This command copies the folder
samplecode and all its files to the storage folder
> neuro cp -r samplecode storage:nero-assistantCopy 'file:///C:/Projects/samplecode' => 'storage://neuro-public/.../nero-assistant/samplecode' 'file:///C:/Projects/samplecode
To move folders from storage to the local host, use the command
neuro cp -r storage:nero-assistant/testlogs file:///Projects
This command copies the storage folder
testlogs and all its files to the local host machine.
> neuro cp -r storage:nero-assistant/testlogs file:///ProjectsCopy 'storage://neuro-public/.../nero-assistant/testlogs' => 'file:///C:/Projects/testlogs' 'storage://neuro-public/clarytyllc/nero-assistant/testlogs' ...
You can remove files or folders from storage using the command
neuro rm [Files/Folder]
For removing folders, you must use the recursive remove command so that the folder contents are also removed:
neuro rm -r [Files/Folder]
To remove files from a storage, use the command
neuro rm storage:nero-assistant/parameters.txt
To remove folders from storage, use the command
neuro rm -r storage:nero-assistant/samplecode
To remove files with a certain pattern, such as
.log, use the command
neuro rm -r storage:nero-assistant/*.log
The moving of files or folders is different from copying files or folders. When you move files or folders, the files and folders are copied to the destination and then removed from the source. To move files or folders, use the command:
neuro storage mv. Optionally, you can also rename a file after it is moved to the destination directory.
To move a file from storage folder to another storage folder and rename the file, use the command
neuro mv storage:nero-assistant\code.txt storage:neuro-tutorial\samplecode.txt
This command moves the file
code.txt from the
nero-assistant storage folder to the
neuro-tutorial storage folder and renames the file to
To move a folder and its contents from storage folder to another, use the command:
neuro mv -T storage:nero-assistant/ModelCode storage:neuro-tutorial/SampleCode
This command copies the folder
ModelCode and all its contents from the
nero-assistant storage folder to the
neuro-tutorial storage folder and renames the folder to
You can use storage folders in jobs. You can mount a storage directory to the container running the job in order to use the storage folder.
Jobs can be slower while using storage folders when compared to using a job container file system. Our experiments show that training CV models takes 10-20% longer when the dataset is read from a mounted storage folder. If such a difference is critical for you, we recommend downloading the datasets for jobs into a non-mounted directory before running the jobs.
It is highly unrecommended to unpack datasets (ZIP, TAR, etc) in a storage folder, as it takes a lot of time.
Before working with storage, you must understand the following:
When you run a job, you can modify files inside its local file system. However, when you terminate a job, all changes are lost. To avoid this, you must use volumes.
A volume’s data persists even after the job container is deleted.
Volumes are a great way to push data to a container, pull data from a container, and share data between containers.
To use a volume when running a job, you must mount the data from the storage to the container. Optionally, you can mount multiple volumes into the container.
To mount a container, use the
--mount parameter in the run command. For example:
neuro run --name job303 --volume storage:nero-assistant/ModelCode:/code:rw --preset cpu-small ubuntu cat /code/train.py
This command mounts the datasets from the
ModelCode folder to the container, for use during the job execution. The folder
/data is used to access the data from within the job.
When in the container, you can update the data in the volume. For example, you can use the following command to update a file from within a container:
ubuntu:/ # echo “New info” >/code/info.txt
You can share files and folders on your storage with others, similar to sharing images. You can specify the access the users can have on files: read, write or manage.
To share a file or folder, use the
neuro share command.
neuro share storage:nero-assistant/ModelCode alice manage
This shares the folder
storage:nero-assistant/ModelCode with the user
You can view the resources that are shared with you using the
neuro acl list command:
> neuro acl list...storage://neuro-public/johndoe/bone-age managestorage://neuro-public/neuromation/midi-generator readstorage://neuro-public/neuromation/public read
