I built myself a docker image from this docker file:
FROM ubuntu:22.04
RUN apt-get update
RUN apt-get upgrade -y
# Install python:
RUN apt-get install software-properties-common -y
RUN add-apt-repository ppa:deadsnakes/ppa -y
RUN apt-get update
RUN DEBIAN_FRONTEND=noninteractive apt-get install python3.11 -y
RUN python3 --version
RUN apt-get upgrade
# Install pip:
RUN apt-get install python3-pip -y
# Install disba (https://github.com/keurfonluu/disba/):
RUN pip install disba[full] --user
(disba is a Python package used for the modeling of surface wave dispersions, and I need this package).
I noticed that when I try importing disba in python3 from a docker container, it works, but when I try to do the same thing in singularity (which is installed on our HPC cluster), it complains:
Singularity> python3
Python 3.10.6 (main, Mar 10 2023, 10:55:28) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import disba
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'disba'
(The way I built the singularity container is by pushing my docker image to dockerhub and then doing
singularity build <container_name> docker://<docker_url>
followed by
singularity run <container_name>
) Unfortunately, I'm at a loss to understand why I cannot import the module I need... I'd appreciate any hints or ideas.
EDIT: Commenting on the answer by @Henrique Andrade:
i) When I type python3.11 in singularity and then try importing disba, the error persists.
ii) Also in docker, when I type python3, Python 3.10.6 is started, but importing disba works, so it doesn't seem to be an issue with the Python version.
When you install disba with RUN pip install disba[full] --user you are potentially installing it in a user account that is not the same that the Singularity image is going to use.
I would install without --user, to install the package globally.
