Package: src:scikit-learn
Version: 0.18-5
Severity: serious
Justification: fails to build from source (but built successfully in the past)
Although this failure happened when the package was binNMUed to add support
for python3.6, it is unrelated. The test failures are for tests run with
python2.7. Below is an extract from the build log [1]:
