For all those who are having this same issue: it happened to me that, suddenly, the pipeline design page changed and, after this, the pipelines modules weren't and couldn't be sorted by type:
How it was before the change (according to Msft doc https://learn.microsoft.com/en-us/azure/machine-learning/tutorial-designer-automobile-price-train-score):
How it is now after the change:
Other consequence of the change was that the top right button 'Create inference pipeline' dissappeared:
How it was before the change (according to Msft doc https://learn.microsoft.com/en-us/azure/machine-learning/tutorial-designer-automobile-price-deploy):
As consequence, after this sudden change, in order to be able to deploy a no-code machine learning model in Azure you have to go to the 'jobs' page and there you can find the 'Create inference pipeline' drop-down list:
It's a shame that after one year, no one in Microsoft have been able to answer this question satisfactorily and to solve this problem that, furthermore, is 'magically' generated by Azure from one moment to another... A lot of wanting to promote the no code tool but afterwards, when people get stucked (normally not deep tech people), no help at all.
Hope this answer can help to those who were lost like me.
