# Fixing the `Servant not allocated` error when running code within DataSphere project cells



## Issue description {#issue-description}

When trying to execute code from Jupyter notebook cells within the DataSphere project, you get one or more error messages:

* `Preparing c1.4 instance`
* `Execute error: Servant c1.4 not allocated: Internal Error`

## Solution {#issue-resolution}

The `Execute error: Servant g1.1 not allocated: Internal Error` message may appear due to a temporary lack of free GPUs in DataSphere. Try using another configuration, e.g., c1.8, or execute code in the cell once again later.

If you are using a custom Docker image in your project, check whether you can reproduce the issue on a public image, e.g., on [Ubuntu](https://hub.docker.com/_/ubuntu).

{% note tip %}

If the issue persists for a while, try opening the project page in private mode of your browser; this will rule out issues on the browser cache side.
