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)) at com.intellij.serviceContainer.ComponentManagerImpl.instantiateClass(ComponentManagerImpl.kt:763) at com.intellij.serviceContainer.ComponentManagerImpl.instantiateClass(ComponentManagerImpl.kt:781) at com.intellij.serviceContainer.LazyExtensionInstance.createInstance(LazyExtensionInstance.java:54) at com.intellij.serviceContainer.LazyExtensionInstance.getInstance(LazyExtensionInstance.java:43) at com.intellij.serviceContainer.BaseKeyedLazyInstance.getInstance(BaseKeyedLazyInstance.java:38) at com.intellij.openapi.util.KeyedExtensionCollector.buildExtensionsFromExtensionPoint(KeyedExtensionCollector.java:155) at com.intellij.openapi.util.KeyedExtensionCollector.buildExtensions(KeyedExtensionCollector.java:128) at com.intellij.lang.LanguageExtension.buildExtensions(LanguageExtension.java:147) at com.intellij.lang.LanguageExtension.buildExtensions(LanguageExtension.java:16) at com.intellij.openapi.util.KeyedExtensionCollector.forKey(KeyedExtensionCollector.java:109) at com.intellij.lang.LanguageExtension.collectAllForLanguage(LanguageExtension.java:125) at com.intellij.lang.LanguageExtension.allForLanguage(LanguageExtension.java:116) at com.intellij.lang.LanguageExtension.allForLanguageOrAny(LanguageExtension.java:160) at com.intellij.codeInsight.daemon.impl.LineMarkersPass.getMarkerProviders(LineMarkersPass.java:134) at com.intellij.codeInsight.daemon.impl.LineMarkersPass.lambda$doCollectInformation$3(LineMarkersPass.java:79) at com.intellij.codeInsight.daemon.impl.Divider.divideInsideAndOutsideInOneRoot(Divider.java:81) at com.intellij.codeInsight.daemon.impl.LineMarkersPass.doCollectInformation(LineMarkersPass.java:77) at com.intellij.codeHighlighting.TextEditorHighlightingPass.collectInformation(TextEditorHighlightingPass.java:56) at com.intellij.codeInsight.daemon.impl.PassExecutorService$ScheduledPass.lambda$doRun$1(PassExecutorService.java:400) at com.intellij.openapi.application.impl.ApplicationImpl.tryRunReadAction(ApplicationImpl.java:1096) at com.intellij.codeInsight.daemon.impl.PassExecutorService$ScheduledPass.lambda$doRun$2(PassExecutorService.java:393) at com.intellij.openapi.progress.impl.CoreProgressManager.registerIndicatorAndRun(CoreProgressManager.java:688) at com.intellij.openapi.progress.impl.CoreProgressManager.executeProcessUnderProgress(CoreProgressManager.java:634) at com.intellij.openapi.progress.impl.ProgressManagerImpl.executeProcessUnderProgress(ProgressManagerImpl.java:64) at com.intellij.codeInsight.daemon.impl.PassExecutorService$ScheduledPass.doRun(PassExecutorService.java:392) at com.intellij.codeInsight.daemon.impl.PassExecutorService$ScheduledPass.lambda$run$0(PassExecutorService.java:368) at com.intellij.openapi.application.impl.ReadMostlyRWLock.executeByImpatientReader(ReadMostlyRWLock.java:167) at com.intellij.openapi.application.impl.ApplicationImpl.executeByImpatientReader(ApplicationImpl.java:178) at com.intellij.codeInsight.daemon.impl.PassExecutorService$ScheduledPass.run(PassExecutorService.java:366) at com.intellij.concurrency.JobLauncherImpl$VoidForkJoinTask$1.exec(JobLauncherImpl.java:188) at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:290) at java.base/java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1020) at java.base/java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1656) at java.base/java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1594) at java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:183) Caused by: java.lang.NoSuchMethodException: PythonCellLineSeparatorProvider.() at java.base/java.lang.Class.getConstructor0(Class.java:3349) at java.base/java.lang.Class.getDeclaredConstructor(Class.java:2553) at com.intellij.serviceContainer.ComponentManagerImpl.instantiateClass(ComponentManagerImpl.kt:720) ... 34 more

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.
