An enlightening talk was given at Kiwi Pycon 2019 that helped me identify the problem: "Python, Threads & Qt: Boom!"

1. Every QObject is owned by a QThread
2. A QObject instance must not be shared across threads
3. QWidget objects (i.e. anything you can "see") are not re-entrant. Thus, they can only be called from the main UI thread.

Point 3 was my problem. Qt doesn't prevent one from calling a QWidget object from outside the main thread, but it doesn't work. Even moving my ProgressDialog to the created QThread will not help. Hence, showing and hiding the ProgressDialog MUST be handled by the main thread.

Furthermore, once a QObject has been moved to a separate thread, rerunning the code will give the error:

All I had to do is close the file before executing it as described in the first comment.

The problem was with from tkmacosx import Button so instead use from tkinter import Button.

EDIT: problem with tkmacosx is now resolved. do update the package

i Have found out a alternate solution for the issue. Not the actual fix anyway it is working.Instead of calling install.sh as starter script i have added another script which will call the install.sh as sourced script. makeself.sh ./test ./test.run "sample installer" ./launcher.sh and launcher.sh wil contain the following content

Launcher.sh file

apt-get is for Ubuntu. Elastic Beanstalk is based on Amazon Linux 2, and you should be using yum. Thus the following will not work:

After some messing around, I have found the solution.

(This is after you have made previous changes regarding my earlier comments which contained code that I later changed to fix this).

It appears that the main error comes from you declaring an object of class showPopup() in the popup() function.

The first fix I had to make was that showPopup was from another file. To fix this, I wrote popup.showPopup() However, this is not right because the code thinks it's a function.

To fix the problem above, I had to import popup in another way. since you are only using the showPopup class, simply do from popup import showPopup. Now get rid of the popup.showPopup() if you put that down already because that doesn't work.

Now, you just have to call save() on the class. To do this, I assigned your showPopup() class to a variable called new and then called new.save() under it.

I also removed popup.mainloop() because it isn't needed for TopLevel()'s

Full Code:

mainScr.py:

The major cause of the issue was the use of the initial Frame object from the MainContainer class to instantiate the Frame in which the Scrollable class is contained. The object of the MainContainer is what should have been passed, this is because it inherits from the Tk class.

Secondly, the mixture of window managers was causing problems. Because of this I switched to pack exclusively. The solution is below.

First of all, the exception happened not because of ipython 3.7, is because Spark can't find this class org.slf4j.Logger in the class path when SparkContext is being initialised (during the the launch of pyspark in this case).

According to your description, you are using a "hadoop free" build of Spark while Spark is depending on Hadoop thus you need to explicitly tell Spark where to get Hadoop's package jars according to Spark's documentation here: https://spark.apache.org/docs/latest/hadoop-provided.html and I think the class we mentioned above is somehow bounded with those jars thus Spark failed to find it.

You can try two solutions:

1. try to update SPARK_DIST_CLASSPATH in spark-env.sh to explicitly tell Spark where to find Hadoop related jars if you have Hadoop in your machine.

2. try use this build spark-2.4.4-bin-hadoop2.7.tgz in case you don't have Hadoop in your machine. In this build, Hadoop related jars are already put together with Spark, so you should not worry about this problem.
