Known issues

  • If you try to install from PyPI and get an error message similar to

    “Could not find a version that satisfies the requirement drymass (from versions: )
    No matching distribution found for drymass”,

    please make sure that you are using Python version 3.6 or later with python --version. If that is already the case, please run pip -vvv install drymass and create an issue with the error messages (e.g. as a screenshot) that you get.

  • If you are using Windows and the installation fails because scikit-image cannot be installed, e.g.

    ” Rolling back uninstall of scikit-image
    Command python.exe […] –compile failed with error code 1 in […]/scikit-image”,

    and you are using the Anaconda Python distribution, please install scikit-image via conda install scikit-image. If you are not using Anaconda, you can install one of the wheels provided by Christoph Gohlke (download e.g. “scikit_image‑0.14.0‑cp36‑cp35m‑win_amd64.whl” if you have installed the 64bit version of Python 3.6, navigate to the download directory and run pip install scikit_image‑0.14.0‑cp35‑cp36m‑win_amd64.whl).
