Hi Kurban Niroomand,
From your Question we understood that you are in this LP: Create a regression model with Azure Machine Learning designer
We have completed the exercise successfully from our side without any issues as shown:
In this exercise we need to follow the steps exactly provided in LP and deployment will take a while. When you try to use the python script you need to remove all the extra spaces in the given script. After that deployment will take around 30 to 40 mins.
If you have any other queries, please don't hesitate to reach out to us along with the screenshots of the error (if any).
Thank you.
