The xFusionCorp Industries ML team uses a Makefile to orchestrate common tasks—data processing, training, testing, and cleanup. A draft Makefile exists at /root/code/fraud-detection/Makefile, but make all does not complete successfully. Bring the Makefile in line with the team’s standard.
Change into /root/code/fraud-detection/ and run make all to observe the current failure.
The corrected Makefile must declare the following six targets and behaviour:
setup – Creates a virtual environment at mlops-venv/ and installs dependencies from requirements.txt;data – Runs python src/data/process_data.py;train – Runs python src/models/train.py;test – Runs pytest tests/;clean – Recursively removes every __pycache__ directory, removes .pytest_cache, and clears the contents of models/;all – Runs setup, data, train, and test in that order.All six target names must be declared as .PHONY so that Make never confuses them with files of the same name.
After your changes, make all must complete without error.
Makefile recipes must be indented with a real tab character, not spaces. Make rejects any recipe that is not tab-indented.
In this task, we have to focus on fixing Makefile properly according to problem description.
Current given Makefile:
# fraud-detection Makefile
setup:
python3 -m venv mlops-venv && mlops-venv/bin/pip install -r requirements.txt
data:
python src/data/process_data.py
train:
python src/models/train.py
test:
pytest tests/
clean:
rm -rf __pycache__
all: setup train test
We can see it has recipe lines indented with spaces instead of tabs.
To fix the Makefile, we need to replace the space-indented recipes with tabs and also make sure all targets are declared as .PHONY. Here is the corrected Makefile:
# fraud-detection Makefile
.PHONY: setup data train test clean all
setup:
python3 -m venv mlops-venv && mlops-venv/bin/pip install -r requirements.txt
data:
python src/data/process_data.py
train:
python src/models/train.py
test:
pytest tests/
clean:
find . -type d -name "__pycache__" -exec rm -rf {} +
rm -rf .pytest_cache
rm -rf models/*
all: setup data train test
After making these changes, you can run make all to ensure that it completes without error. And also run make clean to make sure its clean data that are require to be cleaned.
Missing separator..., Stop. You might face this error. Make sure you have used tab space for each command and removed extra blank lines between two separate commands.
