TROUBLESHOOT

If you are visiting this page it means that you're having issues installing. We deeply apologize for that.

Since the start of the project we've come across different types of issues experienced by the users. This page tries to combine issues, and their solutions. This will allow to give the best install experience to everyone regardless of any programming skills.

  1. Standard Install Troubles
  2. ModuleNotFoundError Trouble
  3. Machine Learning Troubles
  4. Other Issues

Standard Install Troubles

Microsoft Visual C++

If your terminal has too many red error lines, it is likely that this is the issue. Go to this page and install the 2019 Build Tools (not the latest): https://answers.microsoft.com/en-us/windows/forum/windows_other-windows_install/microsoft-visual-c-140/6f0726e2-6c32-4719-9fe5-aa68b5ad8e6d

Wheel

conda install -c conda-forge wheel or pip install wheel

Cvxpy

conda install -c conda-forge cvxpy

Numpy

pip install --upgrade numpy==1.20.2

Poetry

If you get errors about .whl files not existing (usually on Windows) you have to reinitialize the following folder. Just removing the 'artifacts' folder could also be enough:

Platform Location
Linux "~/.cache/pypoetry"
Mac "~/Library/Caches/pypoetry"
Windows "%localappdata%/pypoetry/cache"

When you try to add a package to Poetry it is possible that it causes a similar issue. Here you can remove the 'artifacts' folder again to reinitialize Poetry.

If you run into trouble with Poetry, and the advice above did not help, your best bet is to try

  1. poetry update --lock

  2. conda deactivate -> conda activate gst, then try again

  3. Track down the offensive package and purge it from your anaconda <environment_name> folder, then try again (removing through conda can sometimes leave locks behind)

    Platform Location
    Linux/Mac "/anaconda3/envs" or "/opt/anaconda3/envs"
    Windows "%userprofile%/anaconda3/envs"

  4. Completely nuke your conda environment folder and make a new environment from scratch

  5. Reboot your computer and try again

  6. Submit a ticket on GitHub

JSONDecodeError during poetry install

Sometimes poetry can throw a JSONDecodeError on random packages while running poetry install. This can be observed on macOS 10.14+ running python 3.8+. This is because of the use of an experimental installer that can be switched off to avoid the mentioned error. Run

poetry config experimental.new-installer false

as advised here and it should fix the installation process.

ModuleNotFoundError Trouble

General

In the case when you run into an error of the form ModuleNotFoundError: No module named '_______'. The solution is to install the missing package via pip.

If you get the error that yfinance is not found, you would run

  • pip install yfinance

Then please submit an issue so that we can address why that was not imported.

Please note that the package pmdarima needs to installed through pip install and not through conda install.

pypfopt

pip install PyPortfolioOpt

dotenv

pip install python-dotenv

ally

pip install pyally

Machine Learning Troubles

If you run into issues installing or Cannot convert a symbolic Tensor... at runtime, try this:

conda install -c conda-forge numpy=1.19.5 hdf5=1.10.5
poetry install
poetry install -E prediction

Commands that may help you in case of an error:

  • python -m pip install --upgrade pip
  • pip install pystan --upgrade
  • poetry update --lock

Other Issues

CRLF versus LF

When trying to commit code changes, pylint will prevent you from doing so if your line break settings are set to CRLF (default for Windows). This is because the entire package uses LF (default for Linux/Mac), and it is therefore important that you change this setting to LF before you make any changes to the code.

It is possible that CRLF automatically turns back on, you can correct this with:

git config --global core.autocrlf false

In case you already made coding adjustments, you have to reset your cache, and the changes you made to the code with the following:

git rm --cached -r .
git reset --hard

Unable to run gst from VS Code integrated terminal

Occurs when vscode terminal python version/path is different from the terminal version.

To fix it add this to vscode JSON settings (ref):

    "terminal.integrated.inheritEnv": false,
