My python code is running fine in jupyter but on convertibg to executa

this means a particular module ('x' in this case) was not added to the package. I have seen this occur with packages in the pandas library and win32api; as long as you can identify the package (e.g. 'x'), then it is very easy to fix. To fix this in the UI, open the advanced tab and find the --hidden-import input. Simply paste the module name into this input and then repackage. If the original error is still appearing, you have done this incorrectly.
