Exceptions in pycharm cell model

[lbjunzhe]

Hi, I'm new to python and found that the cell model plugin doesn't work on my Mac, with stack trace attached below. May I ask if there's any constraints in using the plugin? Thanks so much for your help!

com.intellij.diagnostic.PluginException: Cannot create class PythonCellLineSeparatorProvider (classloader=PluginClassLoader(plugin=PluginDescriptor(name=PyCharm cell mode, id=net.fhtagn.pycharm.cellmode, descriptorPath=plugin.xml, path=~/Library/Application Support/JetBrains/PyCharmCE2021.1/plugins/PythonCellMode.jar, version=1.2.1, package=null), packagePrefix=null, instanceId=34, state=active))

Thanks for the report.
v1.3.1 was released just earlier Today. I think this might fix the issue. Can you try updating and let me know if this helps ?

Hi Julien, Thanks for your reply and the update. The updated cell model now will not have an error report in pycharm. But may I ask why there's no output when I hit 'run cell', even when the cell only contains one command of print. Thanks for your help! Best, Jerry

Great, thanks !

Do you see the print command being copied to the console. It may be an issue with the target console not being set properly - you can switch being tmux or internal console in the "Python Cell Mode" settings in preferences.
