Learning how to do relative imports

firstpackage-env conda environment

This project relies on you using the environment.yml file to recreate the firstpackage-env conda environment. To do so, please run the following commands:

# create the conda environment
# note: this make take anywhere from 1-5 minutes
conda env create -f environment.yml

# activate the conda environment
conda activate firstpackage-env

# make this conda environment available as a kernel in jupyter
python -m ipykernel install --user --name firstpackage-env --display-name "firstpackage-env"

Note

Because this project is dependent on the user pip installing the src/ directory as a package, it's important to only create the environment from the project directory and not another location.

Instructions on building a local package

Step 1: Create setup.py file

Example setup.py file to put at the root of your repository for making your src/ directory a package:

from setuptools import find_packages, setup
setup(
    name="src",
    packages=find_packages(),
    version="0.1.0",
    author="Cristian E. Nuno"
)

Step 2. Create an empty file labeled as __init__.py inside of the src/ directory

Step 3. Just once, you will need to pip install your src/ as a package:

Run the following from your root project directory in the Terminal/Command Line:

# note: here we're installing the src/ directory as a package that we called "src"
pip install -e .

Step 4. Manually edit the environment.yml file to include instructions on how to pip install the src package

Unfortunately, the following bash command:

conda env export > environment.yml

does not export both conda and pip requirements in the conda environment. Instead, you will have to manually add the pip installation of the src package like so:

# add this at the end of all conda installs and before the prefix
  - pip:
    - -e .
