FAQ

Using Neptune

How do I find my API token?

In the bottom-left corner of the Neptune app, expand the user menu and select Get your API token.

You can copy your token from the dialog that opens. It's very long – make sure to copy and paste it in full!

How do I find my project name?

Your full project name has the form workspace-name/project-name.

For example, if your workspace name (shown in the top-left corner) is "ml-team" and your project is named "classification", your project string is: "ml-team/classification".

To copy the name, click the menu in the top-right corner and select Edit project details.

Can I change the location of the .neptune directory?

Yes. Normally Neptune creates the .neptune data directory in the CWD. You can:

• have it be created somewhere else by setting a custom path to the NEPTUNE_DATA_DIRECTORY environment variable.
• move it for existing projects: Change location of .neptune folder

What's the difference between runs and the model registry?

Check out our help page: Runs vs Model registry - When to use which

Can I generate and detect data drift with Neptune?

Not directly, as Neptune focuses on experiment tracking. You can, however, use external tools to simulate and detect drifted data, such as TorchDrift and Captum . Afterwards, you can log the result (image with drift distribution for a specific experiment) to Neptune.

Check out an example of logging production data drift with Evidently, or see Essential logging methods for general tips.

Can I deploy Neptune on my own infrastructure?

Yes! See On-prem ≫ Deploying Neptune on your infrastructure.

Can I keep my sensitive data private while working with Neptune?

You can fully control what metadata is logged and sent to Neptune. You can also choose to only track the metadata and version of files instead of uploading their contents to Neptune.

Limits

What are the storage limits?

Included storage quotas are listed on the pricing page on the neptune.ai website. You can always add extra storage to your subscription.

Workspade admins can also set project specific limits, which may differ from the total limit of the workspace.

What is the limit of the number of runs or notebooks?

There are no limits. You can have as many runs and notebooks as you wish.

Projects

How many projects can I have?

The number of active projects is determined by your subscription. Contact your workspace admin for information about the quota.

On your free, individual account, you're limited to one active project. You can have several archived projects, however.

What is an archived project?

An archived project is hidden and in read-only mode, so you can't modify it or add metadata to it. All of the metadata contained within the project remains intact and can be accessed via the Neptune API.

If you unarchive the project, you can use it normally again. Learn more about Archiving projects →

Can I unarchive a project?

Yes, you can unarchive a previously archived project. If your quota is full, you need to upgrade your subscription or archive other projects first.
