I thought I would be able to just have the Openpyxl folder in the same directory as the script for it to import but it does not seem to work. I have put together a bit of code based off a few other threads below to check for openpyxl before it imports. So I can hopefully have the ability to setup openpyxl. I intend to have this bit of code run during

问题 I am spinning up an EMR in AWS. The difficulty arises when using Jupyter to import associated Python modules. I have a shell script that executes when the EMR starts and imports Python modules. The notebook is set to run using the PySpark Kernel. I believe the problem is that the Jupyter notebook is not pointed to the correct Python in EMR. The methods I have used to set the notebook to the correct version do not seem to work. I have set the following configurations. I have tried changing

问题 I have been programming a Python desktop app in Python 3.7 with tkinter. Many of my friends have said using it as an mobile application will get more users. I have been working with sklearn and different modules in Python to run along side the GUI. Is it possible to call that script in Kotlin? 回答1: Yes it is possible. Python has REPL, it's own interactive interpreter and as it turns out Kotlin has a REPL as well. You'll still have to do research and find the interfaces to use with your front
