Low detection rate

[Alex-Beh]

Hello, may I know is it possible to get the same rate as shown in the NodeJS PoseNet demo?

Ubuntu 18.04 with ros melodic
node --version: v14.8.0

I try to run roslaunch ros_posenet posenet.launch and here is the output of the terminal:

Registration of backend tensorflow failed
Error: Could not locate the bindings file. Tried:

============================
Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.

I try rostopic hz /poses and the rate is around 0.154.

average rate: 0.154
