Installation

Introduction

This guide shows the quickest and easiest way to install the project in a virtual environment

pyenv

pyenv allows easy installation of multiple versions of Python on the same machine. It allows the version of python used to be defined at the user and project level. It is a great tool, easy to use, and does its one job very well. It is worth reading the introduction to have an overview of how it works at a high level. It's not necessary to understand the technical internals

Installation instructions for pyenv are here:

https://github.com/pyenv/pyenv#installation

Python 3.10

pysystemtrade currently requires Python 3.10, so once pyenv is installed, the first step is to get that. Get the latest 3.10.x version, at the time of writing it is 3.10.13

$ pyenv install 3.10

Once complete you should be able to see the new version in the output of pyenv versions

$ pyenv versions
  system
  3.7.14
  3.8.5
  3.8.6
  3.8.10
  3.8.13
  3.8.15
  3.8.16
  3.9.6
  3.9.13
  3.10.4
* 3.10.13

Your output will be different, it's just an example

project files

Once we have the correct version of Python, it's time to get the project files.

If you intend to contribute to the project, or run your own instance, you will likely want to clone your own fork

git clone https://github.com/<your_git_hub_id>/pysystemtrade.git

otherwise, you'll want the main repo

git clone https://github.com/robcarver17/pysystemtrade.git

Now we will want to let pyenv know that we want to use Python 3.10 for this project

cd pysystemtrade
pyenv local 3.10.13

this creates a file at the top level of the project .python-version that lets the Python execution environment know to use version 3.10.13. We can check this by running python

$ python
Python 3.10.13 (main, Nov 27 2023, 11:13:49) [Clang 14.0.0 (clang-1400.0.29.202)]
Type "help", "copyright", "credits" or "license" for more information.
>>> 
< ctrl-D to exit >

venv

https://docs.python.org/3.10/library/venv.html

Now we want to create a virtual env (venv) for the project. Doing this will keep all the dependencies for pysystemtrade separate from your other python projects

$ python -m venv venv/3.10.13

This will create a brand new, isolated Python environment inside the pysystemtrade project at the directory <your_path>/pysystemtrade/venv/3.10.13. You can give your environment any name (the venv/3.10.13 bit).

Now activate the virtual environment

source venv/3.10.13/bin/activate

Once your virtual env is activated, the prompt will change. It will look something like

(3.10.13) $

This reminds you that you're in a venv. (You can exit the venv at any time by running deactivate)

dependencies

Now it's time to start setting up the venv. First check to see what is there

(3.10.13) $ pip list

You will probably be prompted to update pip at this time. Do whatever command it suggests.

And now install the dependencies

(3.10.13) $ pip install -r requirements.txt

MacOS (ARM)

If you're running MacOS on one of the new ARM chips, the process is more complex. You'll need Homebrew and the Apple XCode Commandline Development Tools, configured for ARM. Doing that is beyond the scope of this document, type homebrew apple xcode command line tools into your favourite search engine. Once installed and configured, run installation script:

chmod u+x install_dependencies_apple_silicon.sh
./install_dependencies_apple_silicon.sh

Note: this may (unfortunately) become out of date and require some tweaking.

Check dependencies

Check what is installed, should look something like

(3.10.13) % pip list

pysystemtrade

And finally, install the project itself

(3.10.13) $ python setup.py develop

Check stuff works

(3.10.13) $ python

>>> from sysdata.sim.csv_futures_sim_data import csvFuturesSimData

>>> data=csvFuturesSimData()
>>> data
