AttributeError: module 'sys' has no attribute 'argv'

Got this error when loading a model that contains sys.argv

LoadNeuropod modelPath = user_model/neuropod.zip failed: AttributeError: module 'sys' has no attribute 'argv'

This issue related to this python issue , it only happen in embedded python system, and fixed in py3.8.

But to make it backward compatible, we can add this work around

import sys
if not hasattr(sys, 'argv'):
    sys.argv  = ['']

After adding the fix in load_model, this problem still happened in another place.

LoadNeuropod modelPath = /mnt/mesos/sandbox/sandbox/tmp/DLInferenceTransformer_cb7c9b0bcdca_PID_dl_neuropod_integration_tests_ol_MID_tm20200618-034902-UHKBUHNJ-OKLFBD--1131379289 failed: AttributeError: module 'sys' has no attribute 'argv'

Seems the best place to put it is in neuropod/backends/python/executor.py
