#161 Remove pycache directories files on build

[rahit]

Remove all pycache files when you run docker-compose -f local.yml build prediction.

Description

Added a one-line code in Docker file referenced at #161 by @reubano

Reference to official issue

fixes #161

Motivation and Context

Old pycache files can interfere with proper running of docker-compose -f local.yml build and may even cause the following error:

import file mismatch:
imported module 'app.src.tests.test_load_ct' has this __file__ attribute:
  /Volumes/Nahla/alcf/prediction/src/tests/test_load_ct.py
which is not the same as the test file we want to collect:
  /app/src/tests/test_load_ct.py

There should be a convenient script that can be run to remove all pycache files.

How Has This Been Tested?

Run build several times without any error.
