Official releases

Release versions of Spine Toolbox can be found here (only available for 64-bit Windows for now). Download the latest version, install and run spinetoolbox.exe.

Development version

The development version of Spine Toolbox is in the master branch on this repository, and it has all the latest features and bug-fixes. Please note that this version has passed automated testing, but has not been completely manually tested.

Installation

1. Do you have Conda? If yes, go directly to step 2. Otherwise, install either Miniconda (recommended) or Anaconda (good alternative).

2. Open Anaconda Prompt.

3. Create a new environment by typing:

    conda create -n spinetoolbox python=3.8
   

4. Activate the new environment:

    conda activate spinetoolbox
   

5. Install Spine Toolbox and required libraries using pip:

    python -m pip install spinetoolbox
    python -m pip install spine_items
   

6. Run:

   python -m spinetoolbox
   

Running

1. Open Anaconda Prompt.

2. Activate the spinetoolbox environment:

    conda activate spinetoolbox
   

3. Run:

    python -m spinetoolbox
   

Upgrading

1. Open Anaconda Prompt.

2. Activate the spinetoolbox environment:

    conda activate spinetoolbox
   

3. Upgrade requirements using pip (IMPORTANT TO REMEMBER EVERY TIME! Spine Engine, Spine DB API, and Spine Items may have also been updated and a misalignment may cause intractable errors):

    python -m pip install --upgrade spinetoolbox spine_items
   

About requirements

Python 3.7 or Python 3.8 is required.

See file setup.py and requirements.txt for packages required to run Spine Toolbox. (Additional packages needed for development are listed in dev-requirements.txt.)

The requirements include three packages (spinedb_api, spine_engine, and spine_items), developed by the Spine project consortium. Since these packages are developed very actively at the moment, they may get upgraded quite regularly whenever you run python -m pip install --upgrade -r requirements.txt.

Building the User Guide

You can find the latest documentation on readthedocs. If you want to build the documentation yourself, source files for the User Guide can be found in docs/source directory. In order to build the HTML docs, you need to install the optional requirements (see section 'Installing requirements' above). This installs Sphinx (among other things), which is required in building the documentation. When Sphinx is installed, you can build the HTML pages from the user guide source files by using the bin/build_doc.bat script on Windows or the bin/build_doc.sh script on Linux and Mac. After running the script, the index page can be found in docs/build/html/index.html. The User Guide can also be opened from Spine Toolbox menu Help->User Guide (F2).

Troubleshooting

Installation fails

Please make sure you are using Python 3.7 or Python 3.8 to install the requirements.

Installation fails on Linux

If Python runs into errors while installing on Linux systems, running the following commands in a terminal may help:

sudo apt install libpq-dev
sudo apt-get install unixodbc-dev

Problems in starting the application

If there are problems in starting Spine Toolbox, the chances are that the required packages were not installed successfully. In case this happens, the first thing you should check is that you don't have Qt, PyQt4, PyQt5, PySide, and PySide2 packages installed in the same environment. These do not play nice together and may introduce conflicts. In addition, make sure that you do not have multiple versions of these Qt related packages installed in the same environment. The easiest way to solve this problem is to create a blank (e.g. virtual environment) Python environment just for PySide2 applications and installing the requirements again.

Warning: Using the conda-forge channel for installing the requirements is not recommended.

The required qtconsole package from the conda-forge channel also installs qt and PyQt packages. Since this is a PySide2 application, those are not needed and there is a chance of conflicts between the packages.

Note: Supported PySide2 version is 5.14. Spine Toolbox does not support PySide2 version 5.15 (yet).

ImportError: DLL load failed while importing win32api

If you installed Spine Toolbox without Conda on Python 3.8 on Windows, you may see this error when trying to execute a project item. The cause of this error is the package pywin32 version 225. To fix this error, upgrade the package to version 300 using the following command

pip install --upgrade "pywin32==300"

After the process has finished, restart the application. Note: pywin32 v301 does not work.

Contribution Guide

All are welcome to contribute!

See detailed instructions for contribution in Spine Toolbox User Guide.

Below are the bare minimum things you need to know.

Setting up development environment

1. Install the developer requirements:

    pip install -r dev-requirements.txt
   

2. Optionally, run pre-commit install in project's root directory. This sets up some git hooks.

Coding style

• Black is used for Python code formatting. The project's GitHub page includes instructions on how to integrate Black in IDEs.
• Google style docstrings

Linting

It is advisable to run pylint regularly on files that have been changed. The project root includes a configuration file for pylint. pylint's user guide includes instructions on how to integrate the tool in IDEs.

Unit tests

Unit tests are located in the tests directory. You can run the entire test suite from project root by

python -m unittest

Reporting bugs

If you think you have found a bug, please check the following before creating a new issue:

1. Make sure you’re on the latest version.
2. Try older versions.
3. Try upgrading/downgrading the dependencies
4. Search the project’s bug/issue tracker to make sure it’s not a known issue.

What to put in your bug report:

1. Python version. What version of the Python interpreter are you using? 32-bit or 64-bit?
2. OS. What operating system are you on?
3. Application Version. Which version or versions of the software are you using? If you have forked the project from Git, which branch and which commit? Otherwise, supply the application version number (Help->About menu).
4. How to recreate. How can the developers recreate the bug? A screenshot demonstrating the bug is usually the most helpful thing you can report. Relevant output from the Event Log and debug messages from the console of your run, should also be included.

Feature requests

The developers of Spine Toolbox are happy to hear new ideas for features or improvements to existing functionality. The format for requesting new features is free. Just fill out the required fields on the issue tracker and give a description of the new feature. A picture accompanying the description is a good way to get your idea into development faster. But before you make a new issue, please check that there isn't a related idea already open in the issue tracker.
