Python uses wrong Package version

Question

Hi i try to launch the object_detection_tutorial on my PC. When i run the following code to load a (frozen) Tensorflow model into memory.

detection_graph = tf.Graph()
with detection_graph.as_default():
  od_graph_def = tf.GraphDef()
  with tf.gfile.GFile(PATH_TO_FROZEN_GRAPH, 'rb') as fid:
    serialized_graph = fid.read()
    od_graph_def.ParseFromString(serialized_graph)
    tf.import_graph_def(od_graph_def, name='')

ValueError: No op named NonMaxSuppressionV2 in defined operations.

I googled the error and upgrading the tensorflow version to 1.4 should fix the bug. In my code i used tensorflow 1.13 and it worked in google cloud. But even after uninstalling and installing eg. tensorflow 1.4, python uses 1.2.1

Looks like the module is not installed correctly. Try creating a new environment using conda and set up Object Detection in it. It should resolve your issue.

Also, as best practices, it is always better to work on a conda environment than working on the base environment.

Please use below command to create an empty new environment and then install packages on it.

conda create --no-default-packages --name <env_name> python=<version>
