Install Turtlebot3 Hood Waffle Foxy alsora ros2-tensorflow 20210615
Contents
Experience
I started here with the Tensorflow requirements for Foxy and got into trouble. So I changed my strategy to a vanilla Tensorflow and other required components install. There may be overlap and the order my need fine tuning
Documentation

- move Install TensorFlow on Ubuntu Linux Hint

Requirements
Required Dependencies
- Foxy: Installed
Rosdep Dependencies
OpenCV Python
pip -V pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
v 19.3 is minimum.
$ pip install opencv-python
It was already installed.
Tensorflow
Vision Msgs
ROS Foxy's vision-msgs package is required. However, the ROS key had expired causing some confusion.
References
- ROS 2 Tensorflow See Requirements section
- ROS Perception Vision Msgs
- ROS GPG Key Expiration Incident Carefully read Tiryoh's comment carefully from Kat Scott's posting.
- Cannot Install Any More Foxy or Ubuntu Packages My ticket
Install ROS Key
If your ROS key has expired
$ curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add - $ sudo apt update
Insal vission-msgs
$ sudo apt install ros-foxy-vision-msgs
Optional Dependencies
Tensorflow Object Detection Models
I tried going to the following link given by Alsora. The link is broken.
I may have installed the models when I was testing a Udacity Python3 script. See the "Executing Lesson 3 from the Udacity Course" section on page Hood Ubuntu Vanilla Tensorflow Install and Test 20210708
$ pip install -U tensorflow_datasets
Tensorflow Slim
$ pip install --upgrade tf_slim
Docker
To use Docker
Hood ROS 2 Foxy Docker 20210814
Build
Create Foxy Tensoryflow work space
$ git clone https://github.com/alsora/ros2-tensorflow.git $HOME/ros2-tensorflow Cloning into '/home/eepp/ros2-tensorflow'... ... $ mkdir -p $HOME/tf_ws/src $ cd $HOME/tf_ws $ ln -s $HOME/ros2-tensorflow/ros2-tensorflow src
Install dependencies
$ rosdep install --from-paths src --ignore-src --rosdistro foxy -y
- This resulted in errors. I found the resolution here:
- Can't resolve package dependencies when building ros for Ubuntu 16.04
$ rosdep install --from-paths src --ignore-src --rosdistro foxy -y -r
Install Object Detection Models
$ sudo apt-get install -y protobuf-compiler python-lxml python-tk ... ... $ pip install --user Cython contextlib2 ...
The next 3 installs were already satisfied. No additional action.
$ pip install --user Cython jupyter $ pip install --user Cython matplotlib $ pip install --user Cython Pillow
The following failed.
cd usr/local/lib/python3.8/dist-packages/tensorflow/models/research
Corrected
cd /usr/local/lib/python3.8/dist-packages/tensorflow/models/research
The following failed.
$ protoc object_detection/protos/*.proto --python_out=.
Corrected
$ sudo protoc object_detection/protos/*.proto --python_out=.
Missed this the first time I installed
$ echo 'export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/dist-packages/tensorflow/models/research' >> $HOME/.bashrc $ tail ~/.bashrc export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/dist-packages/tensorflow/models/research
Install tf_slim
tf_slim installed earlier. See Optional Dependencies above.
Build and install the ros2-tensorflow package
Double check the symbolic link

$ cd tf_ws
The following fails
$ colcon build
