    python - Can't import phiflow library into google collab - Stack Overflow

    Trying to install the Phiflow library on Google Colab:

    !pip install --upgrade --quiet phiflow

    It installs and says most packages are already satisfied:

    Then trying to import:

    from phi.flow import *
from phi import __version__
print(f"Using phiflow version: {phi.__version__} "

    After importing, this error appears:

    Python 3.10.12. I don't understand it well, so I need help.

    I tried changing python versions, running from different PCs, restarted the session.

    Looked into this issue and indeed got the same error in Google Colab.

    There seems to be an issue with the phiflow and (related) phiml packages themselves, see: https://github/tum-pbs/PhiFlow/issues/184

    Devs are looking into the issue, so I guess it will be fixed soon. But as a temporary workaround they advised to use the dev-build of phiflow and phiml.

    I can confirm the code below to give a working environment when installing and importing in Google Colab:

    !pip install git+https://github/tum-pbs/PhiFlow@develop
!pip install git+https://github/tum-pbs/PhiML@develop
