BuildError: The command '/bin/sh -c pip install --no-cache-dir -r 
requirements.txt' returned a non-zero code: 1

Process finished with exit code 1

Reproducing:

Turn off internet & run docker-based cook

Possible solutions

• Add connection check to PYPI before build.
• Refine logs & set timeout.
