 Sets the number of threads used by each model allocation during inference. This generally increases the speed per inference request. The inference process is a compute-bound process; `threads_per_allocations` must not exceed the number of available allocated processors per node.
 Must be a power of 2. Max allowed value is 32.

 This error usually just reflects a timeout, while the model downloads in the background.
 You can check the download progress in the {ml-app} UI.
 If using the Python client, you can set the `timeout` parameter to a higher value.
