I can't find the folder named modules. The folder named modules is not in the externals folder.Then when I am trying to implement mnist classification project,Imeet the bug:no module named 'gtda.externals.modules Traceback (most recent call last): File "mnist_classification.py", line 13, in from gtda.homology import CubicalPersistence File "/home/sxy/giotto-tda-master/gtda/homology/init.py", line 5, in from .simplicial import VietorisRipsPersistence, WeightedRipsPersistence, \ File "/home/sxy/giotto-tda-master/gtda/homology/simplicial.py", line 18, in from ..externals.python import ripser, SparseRipsComplex, CechComplex File "/home/sxy/giotto-tda-master/gtda/externals/init.py", line 4, in from .modules.gtda_bottleneck import bottleneck_distance ModuleNotFoundError: No module named 'gtda.externals.modules'

Can anyone help me? Thank you very much!

Hi! This is probably due to a bad installation. Could you guide me through the steps you followed to install the library?

songxinyuty commented 3 years ago

I download master from https://github.com/giotto-ai/giotto-tda/, then create the new linux environment which python =3.6.13 , then run the command: python -m pip install -U giotto-tda

Thanks! Just to check: are you specifically wishing to build from sources (it is much easier to just install the PyPI distribution), or are you downloading the repository just as a way to have the notebooks?

Additionally, could you please uninstall, then remove the cloned repository, then repeat the steps you performed but share the outputs with us here?

In addition, could you please make sure that pip itself is up-to-date? You can run python -m pip install -U --upgrade pip to upgrade pip to the latest version. Old versions of pip can misbehave in Linux systems.

Thanks for your advice. I make sure that pip is up-to-date. I uninstall the repository and then install the PyPI distribution again,but I meet the same question: Traceback (most recent call last): File "", line 1, in File "/home/sxy/giotto-tda-master/gtda/homology/init.py", line 5, in from .simplicial import VietorisRipsPersistence, WeightedRipsPersistence, \ File "/home/sxy/giotto-tda-master/gtda/homology/simplicial.py", line 18, in from ..externals.python import ripser, SparseRipsComplex, CechComplex File "/home/sxy/giotto-tda-master/gtda/externals/init.py", line 4, in from .modules.gtda_bottleneck import bottleneck_distance ModuleNotFoundError: No module named 'gtda.externals.modules'

Hi, thanks! I wasn't sufficiently clear. I meant if you could share the outputs of the python -m pip install -U giotto-tda step.

I have solved the issue .Maybe I haven't clean it completely, Now it can work. Thank you very much!
