test:TypeError: expected str, bytes or os.PathLike object, not None Type

Question

I am trying to run this code in anaconda python3.7, but I'm getting below error:

TypeError: expected str, bytes or os.PathLike object, not NoneType

This is for windows 10, running on python 3.7

import os
import sys
import argparse
import numpy as np
import tensorflow as tf
sys.path.append(os.getcwd())
from model import get_model
from utils.visualize import plot

def sigmoid(x):
return 1.0 / (1.0 + np.exp(-x))

PARSER = argparse.ArgumentParser(description='CLI for inference')
PARSER.add_argument('--file', type=str, help='Image on which to perform inference')
PARSER.add_argument('--savedmodel', type=str, default='model/iter-51042', 
help='SavedModel directory')
PARSER.add_argument('--k', type=int, default=5, help='Top K predictions to print')
PARSER.add_argument('--visualize', action='store_true', default=False, help='Whether to 
visualize <file>')
PARSER.add_argument("-f", "--fff", help="a dummy argument to fool ipython", default="1")
ARGS = PARSER.parse_args()

FILE = ARGS.file
SAVED_MODEL = ARGS.savedmodel
K = ARGS.k
VISUALIZE = ARGS.visualize

pt_cloud = np.load(FILE)
pt_cloud = np.expand_dims(pt_cloud, axis=0)

So when I run python manage.py test trips.tests, I'm getting the this traceback error:
