Hello,
I want to predict the amount of sold items of a specific product by a specific shop. But I encounter some errors. Please see the details below.
---------PROBLEM DESCRIPTION---------
I created and trained my predictor successfully. But I get errors when making predictions.
---------DATA---------
I have a table with the following columns:
sale_id
,date_of_sale
,shop
(that made this sale),product_code
(a product that was sold),amount
(number of items that were sold; it is a column to be predicted),total
(total sale price; this column is not relevant for making a forecast).This table is used to create a predictor. I attach here the sales_data.csv file whose data I loaded into this table.
---------STEPS TO REPLICATE---------
Below are the steps that I performed:
1. I created the
sales_data
table in my database (PostgreSQL), and loaded the data from the sales_data.csv file into thesales_data
table.2. I run a query to create a predictor:
My predictor was created and trained without any errors/warnings.
3. I run a query to predict the sold amount for specific data:
This query returned an error:
4. I run another query to make predictions for many rows at once:
This query returned an error:
Please advise how I can fix the errors in steps 3 and 4.
Thank you.
