During git cloning, a ssh key problem.
=> found a solution by associating a public key according to

"
First start by setting up your own public/private key pair set. This can use either DSA or RSA, so basically any key you setup will work. On most systems you can use ssh-keygen.

First you'll want to cd into your .ssh directory. Open up the terminal and run:
cd ~/.ssh && ssh-keygen
Next you need to copy this to your clipboard.
On OS X run: cat id_rsa.pub | pbcopy
On Linux run: cat id_rsa.pub | xclip
On Windows (via Cygwin/Git Bash) run: cat id_rsa.pub | clip
Add your key to your account via the website.
Finally setup your .gitconfig.
git config --global user.name "bob"
git config --global user.email bob@... (don't forget to restart your command line to make sure the config is reloaded)
Thats it you should be good to clone and checkout.

Just before source compilation, cmake needs to be installed.

Just before installing OpenAI gym baselines (cmake can be skipped as it is already installed as above, cf. the following git):
$ sudo apt install cmake libopenmpi-dev python3-dev zlib1g-dev

Just before test run, a few modules and packages need to be installed:
$ pip3 install opencv-python
$ pip3 install pandas
