Unfortunately, scikit-image 0.15 and above no longer work with your installed version of Python ({}). You therefore have two options: either upgrade to Python {}, or install an older version of scikit-image. For Python 2.7 or Python 3.4, use $ pip install 'scikit-image<0.15' Please also consider updating `pip` and `setuptools`: $ pip install pip setuptools --upgrade Newer versions of these tools avoid installing packages incompatible with your version of Python. .cSsg|] }t|qS)str).0vrrV/var/www/html/venv/lib/python3.8/site-packages/skimage/_shared/version_requirements.py sz)ensure_python_version..) isinstancetuplesys version_infoplatformr ImportErrorformatjoin) min_versionrrrr ensure_python_versions   rcCsz|dkr t|t|kWS|dkr>t|t|kWS|dkr\t|t|kWS|dkrzt|t|kWSWdSWntk rYdSXdS)a) Check version string of an active module against a required version.
