Unable to Install tokkio-3stream-no-ui Helm Chart from NGC (403 Forbidden) - ACE 5.0.0-beta on GCP

Hi All,

I’m trying to deploy NVIDIA ACE Tokkio 3-stream (no UI) using the Helm chart provided in the NGC repo:

  • Chart: tokkio-3stream-no-ui
  • Version: 5.0.0-beta
  • Repo: https://helm.ngc.nvidia.com/nvidia/ace/
  • Platform: GCP
  • Use Case: Automated one-click deployment script from NVIDIA-provided ACE repo.

When running:

helm install my-release nvidia/ace/tokkio-3stream-no-ui \
  --version 5.0.0-beta \
  --username '$oauthtoken' \
  --password "$NGC_API_KEY"

I receive:

Error: failed to fetch https://helm.ngc.nvidia.com/nvidia/ace/charts/tokkio-3stream-no-ui-5.0.0-beta.tgz : 403 Forbidden

More Context

  • I verified my NGC API key works with other ngc CLI operations.

  • I already added and updated the repo successfully:

    helm repo add nvidia https://helm.ngc.nvidia.com/nvidia/ace \
  --username '$oauthtoken' --password "$NGC_API_KEY"
helm repo update

Deployment Failure Log (via NVIDIA one-click GCP script)

  ]
}

Is this chart restricted, moved, or removed from NGC?
Is there an updated public location for the Helm charts?
Is additional NGC access required to install ACE/Tokkio Helm charts?

Any help would be appreciated.

Thanks!

Hi @khushi.patni1,

This chart requires that you are a member of the ACE early access program. You can register here ACE Early Access.

Best,

Sophie

UPDATE: AUGUST 2025 - you should now be able to access this content with only an NVIDIA Developer License.

Can you update this link? It just leads back to the main page. Is there another page for early access to more programs? @sophwats

Hi @sallen23,

The ACE early access program has now ended - an NVIDIA developer license should give you access to all of the relevant content.

Best,

Sophie
