Rasa version: 1.8

Rasa X version (if used & relevant):

Python version:3.7.1

Operating system (windows, osx, ...):windows

Issue:
'rasa.model.unpack_model ' Triggered 4 times and did not clean up when the program was closed.
4 folders are generated in the directory 'CreatorTemp' after 'rasa shell -vv'.
Only the last two directories are deleted when the program exits.
After several starts, I got a lot of useless cache directories

Error (including full traceback):

Thanks for the issue, @erohmensing will get back to you about it soon!

You may find help in the docs and the forum, too 🤗

I've fixed the bug about the undeleted temporary files.
But I still don't understand why rasa has to decompress it many times.When I execute 'rasa shell'.
First decompression :

 rasa.cli.shell.shell

Second decompression

 rasa.cli.run.run

I think these two places are more about checking the validity of the model structure than using it.
I modified them according to this idea

[erohmensing]

Sorry, I'm confused. With I've fixed the bug and I modified them according to this idea, where are you fixing things? Was it an issue with the code or your setup?

[glacierck]

The main causes of useless cache directories are code issues.
Here's my solution, It solves the problem of useless cache but not the problem of useless decompression behavior. Show sadness for my hard disk.
