umt won't work

Open aweussom opened this issue 3 years ago • 9 comments

I followed the instructions at https://github.com/nathanrooy/rpi-urban-mobility-tracker

I'm getting this error: (The first three lines as apparently just noise)

Exactly the same problem in Ubuntu as in Raspberry PI OS/Docker.

I confirm, I have the same problem.

First you need to locate where your Python packages were installed, then in "deep_sort_tools/generate_detections.py" you need to change these two lines from :

self.input_var = tf.compat.v1.get_default_graph().get_tensor_by_name(
     f"net/{input_name}:0")
self.output_var = tf.compat.v1.get_default_graph().get_tensor_by_name(
     f"net/{output_name}:0")

to this:

self.input_var = tf.compat.v1.get_default_graph().get_tensor_by_name(
     f"{input_name}:0")
self.output_var = tf.compat.v1.get_default_graph().get_tensor_by_name(
     f"{output_name}:0")

This is referred to the ubuntu installation I would assume, right? By making this change has everything worked correctly afterwards?

This is on Ubuntu also - however - the latest UMT code from GitHub have fixed this.

I have a NEW issue, bit I will create another thread for that :-)

These two erranous lines are still there in the docker install.

This worked for me in RPi OS

In my case, yes.
