Environment Setup ​

On this page, we'll go through how to prepare your environment before installing Jesse. We'll cover three major operating systems:

TIP

Remember that you don't need to do any of these steps if you want to use Docker instead.

TIP

A good practice for providing an environment for running Python applications is setting up Python virtual environments. Especially when you have different projects with their own dependencies, you can create an isolated environment regardless of what dependencies every other project has. Here you can find more information on creating virtual environments.

Remote server ​

In case you intend to use a remote server, we have step-by-step Youtube screencasts for you:

Ubuntu ​

We provide bash scripts that install all the required stack and pip packages including Jesse itself on a machine running a fresh Ubuntu 20.04 LTS installation.

sh
source <(curl -fsSL https://raw.githubusercontent.com/jesse-ai/stack-installer/master/ubuntu-20.04.sh)

In case a fresh install isn't possible for you, look at the commands used by our script and execute only the ones that suit your environment:

WARNING

You should have at least 2GB RAM or the build of ta-lib might fail. A workaround is using a prebuilt wheel (.whl) of ta-lib.

By default, values of POSTGRES_HOST and REDIS_HOST are set to postgres and redis which are the default values of the official Docker containers. You have to change them both to localhost.

PostgreSQL ​

Now you have to create the database, user, and password. You can do this by running the following commands:

sh
# switch to postgres user
sudo su - postgres
# open PostgreSQL CLI
psql
# create database
CREATE DATABASE jesse_db;
# create new user
CREATE USER jesse_user WITH PASSWORD 'password';
# set privileges of the created user
GRANT ALL PRIVILEGES ON DATABASE jesse_db to jesse_user;
# exit PostgreSQL CLI
\q
# exit postgres user (back to root)
exit

Your environment should now be ready to install and run Jesse.

macOS ​

Installation on macOS is easy thanks to Homebrew. If you don't have Homebrew installed, install it by running:

sh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

TIP

Starting v0.23.1, Jesse can be installed natively on mac machines with Apple Silicon (M1). The performance on it amazing is BTW!

The only dependency package that doesn't work with M1 macs yet is numba. However, we made the numba package optional. Meaning that if you are on an M1 machine, it won't install it, and the indicators that use it will still work but will be a little slower.

Installing scipy is a bit tricky. We recommend installing it with Homebrew:

brew install openblas
export OPENBLAS=$(brew --prefix openblas)
export CFLAGS="-falign-functions=8 ${CFLAGS}"
brew install scipy

Now install Python, ta-lib, Redis, and PostgreSQL by running the below commands one by one:

sh
brew install [email protected]
brew install ta-lib
brew install redis
brew install postgresql

PostgreSQL ​

The last step is to create a PostgreSQL database and user:

sh
# open PostgreSQL CLI
psql postgres
# create database
CREATE DATABASE jesse_db;
# create new user
CREATE USER jesse_user WITH PASSWORD 'password';
# set privileges of the created user
GRANT ALL PRIVILEGES ON DATABASE jesse_db to jesse_user;
# exit PostgreSQL CLI
\q

That's it. You should now be able to install and run Jesse.

Windows ​

Python and pip ​

Download the official Python installer. It doesn't matter whether you choose the executable installer or the web-based installer. What matters is to choose the right version for your system type. If you are on 32bit Windows download Windows x86 ... installer. If you are on 64bit Windows get the Windows x86-64 ... installer.

TIP

Not sure which system type you are on? Open a file explorer window. Right-click on This PC and then Properties. Under System there is System type.

WARNING

Make sure to check Add Python 3.X to PATH during installation. In the end, the installation may ask you to disable the length limit for the PATH. Make sure to do that, by clicking that. You can leave the other settings as they are.

Now check if the installation was successful by opening a CMD and typing python --version. You should get Python 3.X.X according to the version you just installed. Type pip --version. You should get pip 19.X.X from ....

TIP

In case you get:

python/pip is not recognized as an internal or external command,
operable program or batch file.

Then you probably didn't check Add Python 3.X to PATH. Start again or add it to your path manually. To edit your PATH variable use the windows search and search for environment you should see Edit environment variables for your account. Click that. Search for the PATH variable in the user section. Select it and click Edit. Click Browse and find your python installation folder. You are sure Python is in the PATH? Restart your CLI and/or your machine might help.

Redis ​

The bad news are there is no version of Redis for windows. The good news: We can install Redis with the help of a virtual machine (VM) or windows subsystem. Here we will be using a linux on the windows subystem:

Before installing any Linux distros for WSL, you must ensure that the "Windows Subsystem for Linux" optional feature is enabled:

Open PowerShell as Administrator (windows search for "PowerShell" > right click > "run as administrator) and type: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Restart your computer when prompted.

Now download and install Ubuntu 20.04 from the Microsoft Store.

Launch ubuntu you will be promted to select a username and password for ubuntu.

After that install Redis (you will be asked for the password you just set):

sh
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install redis-server
    redis-cli -v

You should end up with something like that: redis-cli X.X.X

This will start the server. You can close the windows after that:

    redis-server

But you need to start Redis server after each system reboot by running the redis-server command in the ubuntu terminal.

Another alternative is Memurai - which has to be restarted every 10 days in the free version though.

PostgreSQL ​

Download and install a version greater than 11.2 matching your system type (Windows x86-64 or x86-32).

WARNING

Make sure to save the password you set for the superuser. You can unselect the components pgAdmin and Stack Builder. You can leave the other settings as they are.

Now add PostgreSQL to your PATH. To edit your PATH variable use the windows search and search for environment. Click on Edit environment variables for your account. Search for the PATH variable in the user section. Select it and click Edit. Now click Browse and find your PostgreSQL installation folder. Select the bin folder and save everything. The added path should look something like C:\Program Files\PostgreSQL\12\bin.

Now open a CMD to create the database for Jesse by executing the following commands:

sh
# Switch to postgres user. You will be asked for the password
psql -U postgres
# Create the database
CREATE DATABASE jesse_db;
# create a new user
CREATE USER jesse_user WITH PASSWORD 'password';
# set privileges of the created user
GRANT ALL PRIVILEGES ON DATABASE jesse_db to jesse_user;
# exit PostgreSQL CLI
\q

Talib ​

To install Talib on Windows the easiest way is to use a prebuilt binary. Go here and search TA-Lib and download a version >= 0.4 matching your system and python version.

Example:

  • TA_Lib‑0.4.17‑cp38‑cp38‑win_amd64.whl: this would be the version for Python 3.8 (cp38) and Windows 64bit (win_amd64)
  • TA_Lib‑0.4.17‑cp38‑cp38‑win32.whl: this would be the version for Python 3.8 (cp38) and Windows 32bit (win32)

Now open CMD and go the directory where you downloaded the binary file and run:

sh
pip install {downloaded_binary_file}
# for example:
# pip install TA_Lib‑0.4.17‑cp38‑cp38‑win_amd64.whl

Now check if it worked by running: pip list you should now find ta-lib in that list.

TIP

You don't have to use the prebuilt wheel. You can build it yourself, but you have more work this way. There is a tutorial: HERE

Cython ​

Run:

sh
pip install cython

That's it! You should now be able to install and run Jesse.
