The SECRET_KEY setting must not be empty

I am using ubuntu 16.04.
I have generated a key online for django from http://www.miniwebtool.com/django-secret-key-generator/ then input in the /opt/lexpredict-contraxsuite/contraxsuite_services/settings.py as ( SECRET_KEY = "yj6o@&vrar6^l1u68!bxugj@xr4&5)zzk!h1qw&13^&@2d3wp#") and also in /opt/lexpredict-contraxsuite-deploy/local/local_settings.py files.
after following all the steps of local machine installation setup mentioned in
https://github.com/LexPredict/lexpredict-contraxsuite/blob/master/documentation/Installation%20and%20Configuration/Quick%20Start%20Installation%20Guide%20for%20Linux.pdf
I am executing the following commad:
bash setup_local.sh | tee -a log.txt

after few steps of exection, I am getting the following error:
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty

need help to resolve this. I don't know where I am doing mistake.

Currently we use docker based approach for application deployment, see
https://github.com/LexPredict/lexpredict-contraxsuite/tree/master/docker

We had a lot of changes since we used lexpredict-contraxsuite-deploy for deployment last time.
I made some important updates there and it should work now.
So please update it using git pull and try again.

But I would recommend to use docker.

@reddalexx : Even after taking the update of 'lexpredict-contraxsuite-deploy' using git pull, I am facing the same issue. Below is the stack trace.

That means that probably local_setting.py template wasn't transfered into destination folder.
go to deploy folder cd lexpredict-contraxsuite-deploy
activate virtual environment source ve/bin/activate
run fab -c local/fabricrc upload_template_and_reload:settings to apply local settings
run fab -c local/fabricrc start to start application
then open browser at localhost

@reddalexx: As per your suggestion, I have tried the docker setup and followed the steps mentioned here: https://github.com/LexPredict/lexpredict-contraxsuite/tree/master/docker
But it didn't load the Contraxsuite application at http://localhost:65080
I have used a Clean Ubuntu 16.04 machine having more than 8GB RAM. Below are the screenshots attached of the step by step execution.

@reddalexx: Any update on the above issue?

@SandeepKumarJoshi @reddalexx
I am having the same issues. For the first approach "lexpredict-contraxsuite-deploy", i used the script to copy the settings but then I ran to celery issue that is the application could not find "apps" worker.
The second approach docker also does not work. The dockers are deployed but it shows the same errors for me as @SandeepKumarJoshi . Any help would suffice. Thanks.

I ran into the same issue:
The SECRET_KEY setting must not be empty
Udpate base/fabricrc with the SECRET Key
SECRET_KEY = <secret key without @ to be specified without key>

Application is now up with few other issues like Email verification and Super User Account but was able to fix that.
