Any ideas @jannes-m or @Nowosad ?

All these lines seem to be failing, I'm trying to re-run them:

geocompr/15-eco.Rmd

Lines 508 to 534 in 5855dea

	```{r 15-eco-24, eval=FALSE, cache=TRUE, cache.lazy=FALSE}
	# hyperparameter tuning
	set.seed(08012024)
	autotuner_rf$train(task)
	```
	```{r 15-eco-25, cache=TRUE, cache.lazy=FALSE, eval=FALSE, echo=FALSE}
	saveRDS(autotuner_rf, "extdata/15-tune.rds")
	```
	```{r 15-eco-26, echo=FALSE, cache=TRUE, cache.lazy=FALSE}
	autotuner_rf = readRDS("extdata/15-tune.rds")
	```
	```{r tuning-result, cache=TRUE, cache.lazy=FALSE}
	autotuner_rf$tuning_result
	```
	### Predictive mapping
	The tuned hyperparameters\index{hyperparameter} can now be used for the prediction.
	To do so, we only need to run the `predict` method of our fitted `AutoTuner` object.
	```{r 15-eco-27, cache=TRUE, cache.lazy=FALSE, warning=FALSE}
	# predicting using the best hyperparameter combination
	autotuner_rf$predict(task)
	```
