Tensorflow NotFoundError: data/mscoco_label_map.pbtxt; No such file or directory - tensorflow

Question

I am trying to run this script from the YouTuber sentdex, but I get this error:
This call to matplotlib.use() has no effect because the backend has already
been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.
The backend was *originally* set to 'TkAgg' by the following code:
File "Desktop/object.py", line 11, in <module>
from matplotlib import pyplot as plt
File "/usr/local/lib/python2.7/dist-packages/matplotlib/pyplot.py", line 71, in <module>
from matplotlib.backends import pylab_setup
File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/__init__.py", line 16, in <module>
line for line in traceback.format_stack()
import matplotlib; matplotlib.use('Agg') # pylint: disable=multiple-statements
Traceback (most recent call last):

tensorflow.python.framework.errors_impl.NotFoundError: data/mscoco_label_map.pbtxt; No such file or directory
OS: Ubuntu 18.04

Could you please help me ?

Answer 1

It would help immensly if you provided the file/function you called to produce the traceback. However, in absence of that and based on the below:
tensorflow.python.framework.errors_impl.NotFoundError: data/mscoco_label_map.pbtxt; No such file or directory
The *_label_map.pbtxt path is specified in two lines of the model.config file (exact line numbers depends on the model you chose). It appears one or both the training/test file paths are incorrect.
