Flask, wsgi and deploy

(pardon my english)
Hello,
I've a problem for a deploy on a gandi server.
After a git push on a gandi server, I'm proceeding a deploy :
ssh [url] deploy default.git
I obtain an "Internal Error Server".
My log/www/uwsgi.log said :

I have not idea how can I solve this problem... ?
Anyone understand this problem ? Thank you

What does this capistrano error mean when doing an AWS file fetch via cap tasks?

In my deploy/development.rb, I have the following line:-
set :env_path, 's3api get-object --bucket <bucket_name> --key <file_name> <file_name>'
In my cap file, I have the following task defined:
task :download_configs do
on roles(:all) do
within release_path do
execute :aws, "#{fetch(:env_path)}"
end
end
# on roles(:db) do
# within release_path do
# execute :aws, "#{fetch(:env_path)}"
# end
# end
end
But on cap deploy,I am seeing the following errors:-
cap aborted!

Please help me identify what is going wrong here!

Shot in the dark (I'm not a Python dev), but you might be able add the following to deploy.rb:
set :default_env, {
'LANG' => 'en_US.UTF-8'
}
Derived mostly from https://github.com/matplotlib/matplotlib/issues/5420#issuecomment-154454607
I would check to see if you can run the command manually on the server. If you cannot, then figure out how to without Capistrano. If you can, perhaps see if there is some configuration in .bashrc or .bash_profile that can be added to the Capistrano config.

SyntaxError: invalid syntax

You are using a Python package which is for Python 2.x and uses old Exception syntax (gevent.hub).
You need to upgrade the violating module to Python 3.x compatible version.
If this is not possible then you need to deploy your application on Python 2.x.

Any hints on how can I get rid of it ? I will update this post with any necesarry information that you'll need.

Update the python version to 2.7 or greater. One of the problems is that you don't have argparse which is on the newest version of python.
