# ERR\_RECIPE\_CANNOT\_USE\_ENGINE: Cannot use the selected engine for this recipe[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_RECIPE_CANNOT_USE_ENGINE.html#err-recipe-cannot-use-engine-cannot-use-the-selected-engine-for-this-recipe "Permalink to this headline")

The selected execution engine / backend for this recipe cannot be used. The specific error message should contain more details on the precise cause of this error.

The input dataset, model, or other recipe settings are not compatible with the selected engine for this recipe.

Some common examples include:

* Using the SQL engine with non-SQL input datasets

* Using SQL computed columns on DSS engine

* Changing the model (output of a training recipe or input of a scoring

recipe) for one with a different backend.

* Using features not supported by the engine, like text features

for ML in SQL.

## Remediation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_RECIPE_CANNOT_USE_ENGINE.html#remediation "Permalink to this headline")

Make sure that the recipe settings and inputs are compatible with the selected engine. Change the engine if necessary.

If the recipe’s inputs were recently changed, that is probably a good place to start looking.
