Thank you very much for any help!
I solved this one by a hack. Apparently there's a bug in that tasks file for the version of python we both seem to be using. (Are you on a raspberry PI?) I simply edited /usr/local/lib/python3.7/dist-packages/trollius/tasks.py and deleted the 'async' reference at the top of the file and then deleted the entire function at line 565. (it even says it's been deprecated)

I'm using nvidia's jetson nano. I searched and found no ROS2 installation that already has python3 nor ros noetic. That's why it's important to be able to install. Did you even use some algorithm in python3 and it worked well? Deep Learning algorithm? @metalglove
I knew this was going too well:

I solved this by wiping the SD card on my pi and reinstalling from scratch.

I also had massive problems with installing wxTools, so I skipped as I didn't need it (everything I do is headless). I also changed my build to a ros_base instead of a desktop_full.
So if anyone is coming here to successfully build melodic on a headless raspberryPi ZeroW running rasbian buster the changes I needed were:
-
CHANGE:
rosinstall_generator desktop_full --rosdistro melodic --deps --tar > melodic-desktop-full.rosinstall
TO:
rosinstall_generator ros_base --rosdistro melodic --deps --tar > melodic-base.rosinstall
-
CHANGE:
wstool init -j8 src melodic-desktop-full.rosinstall
TO:
wstool init -j8 src melodic-base.rosinstall
-
DELETE:
pip install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-18.04 wxPython
-
CHANGE:
sudo ./install_skiprosdep check --from-paths src --ignore-src | grep python | sed -e "s/^apt\t//g" | sed -z "s/\n/ /g" | sed -e "s/\<python\>/python3/g"
TO:
sudo ./install_skiprosdep check --from-paths src --ignore-src | grep python | grep -v wxtool | sed -e "s/^apt\t//g" | sed -z "s/\n/ /g" | sed -e "s/\<python\>/python3/g"
(check the back quotes in these lines, the markdown is messing it up - basically added| grep -v wxtool
to the chain.
Thanks to everyone here, I've now got ros1 running on a Pi using python3.
Thanks for the instructions! I'm following them and they are helpful! Can I also ask how you figured out the instructions? Did you get them from some other sources? I tried to search in the ROS official website and ROS source code repositories but didn't seem to find them. How did you find the instructions?

Two errors were encountered during setting up with this tutorial:
- When catkin_make:
File "/usr/lib/python3.6/signal.py", line 47, in signal TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object
This will not affect launching roscore just as you posted before.
- When rosrun somepacakge somecode.py:
rosrun topic_demo pytalker.py Traceback (most recent call last): File "/root/catkin_ws/src/ROS-Academy-for-Beginners/topic_demo/scripts/pytalker.py", line 3, in <module> import rospy File "/root/ros_catkin_ws/install/lib/python3/dist-packages/rospy/__init__.py", line 47, in <module> from std_msgs.msg import Header File "/root/ros_catkin_ws/install/lib/python3/dist-packages/std_msgs/msg/__init__.py", line 1, in <module> from ._Bool import * File "/root/ros_catkin_ws/install/lib/python3/dist-packages/std_msgs/msg/_Bool.py", line 5, in <module> import genpy File "/root/ros_catkin_ws/install/lib/python3/dist-packages/genpy/__init__.py", line 34, in <module> from . message import Message, SerializationError, DeserializationError, MessageException, struct_I File "/root/ros_catkin_ws/install/lib/python3/dist-packages/genpy/message.py", line 44, in <module> import yaml File "/usr/lib/python3/dist-packages/yaml/__init__.py", line 284 class YAMLObject(metaclass=YAMLObjectMetaclass): ^ SyntaxError: invalid syntax
This is an interesting error.. Python seems to be complaining about the python3's metaclass syntax here. And with the traceback log, ROS is trying to run with python3 here but somehow ended up using python2 when the error happens.
Does anyone have any insight?
@zzh112119, Hi, I have same question with you. Is your problem related to YAMLObject Syntax solved by uninstall python2? which installed accidentally after install libboost?

Did you check this? If the head of the file is :
#!/usr/bin/env python
Make sure that it points to python3
Or change it to:
#/usr/bin/python3
(or whatever your path is the executable)
@graemerae, thanks for your reply, after changing to #!/usr/bin/python3, it's working, cheer!

Does roscore and a simple python publisher working? This problem should be fine.

@metalglove if i change your script from melodic to noetic it should work? i will test it today...

There is a supported noetic version for Python3.
@metalglove thanks for taking the time to reply on a sunday :) i worked until 6 am yesterday haha!
I am not 100% sure what I did (well, our life), but I did manage to install on a ubuntu20.04 image, python3.8 and ros-noetic without building the same way you did (that's why I had uncertainty about it working).
If you have time maybe to explain to me why this worked compared to your solution I'd highly appreciate it as a learning experience :)

Also, I am trying to build a docker image with ubuntu20.04, cuda11 (or 10) with cudnn8 (or 7), but all the available images (official) are either ubuntu18 or below with cuda10, cudnn7, and the ubuntu20 ones have only cuda11 and the package for cudnn8 do not exist yet.. ugh!
Everything worked great until I tried to build it!

I am getting these issues, I followed the same steps listed in https://www.miguelalonsojr.com/blog/robotics/ros/python3/2019/08/20/ros-melodic-python-3-build.html
Does this setup mean that all new ros packages (e.g my own) need to be installed in the build workspace (ros_catkin_ws)?
Unfortunately I couldn't get this python3 configuration to work for me when I was experimenting with this. Having this issue as well:

What would be the best way to revert the changes made by 'gistfile1.txt' to get back to using Python2.7 with catkin build?

UPDATE:
Never-mind. For my particular situation 'catkin_tools' was not completed uninstalled all the way, so had to go into '/usr/local/bin' and manually delete the catkin related binaries as well as as the ros binaries then re-installed ros-melodic and python-catkin-tools and I was back up and running with my old setup using Python2.7.
hi @metalglove, I have followed ur way and succesfully installed. after using the source " source ~/ros_catkin_ws/install/setup.bash" i can use roscore and it works without ant error. But I have a question how can i install moveit for ros melodic. Because whenever i try it gives error it can not locate the file. even if i use source before installing. What I am doing wrong ?
Example I open new terminal:
source ~/ros_catkin_ws/install/setup.bash
sudo apt install ros-melodic-moveit
and here is the error:
E: Unable to locate package ros-melodic-moveit

HI @MBaranPeker,
You cannot just use sudo apt install ros-melodic-moveit
since this is a binary version with Python 2.
You should download the source code and then build it with python 3. Here is the guide could probably help you.
Let me know if this works for you.
Cheers,
Hi, @YijiongLin. Thank you so much. It is working now.
Hey! I was able to install ROS, but am not able to import rospy. I am trying to install ROS on Google Colab and the following were the commands that I used to install ros-base:

When I do pip list, rospy shows up in the list. But when I try to import rospy, I get the following error:
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-8-fb60b5b51009> in <module>()
----> 1 import rospy
ModuleNotFoundError: No module named 'rospy'
---------------------------------------------------------------------------
NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.
To view examples of installing some common dependencies, click the
"Open Examples" button below.
---------------------------------------------------------------------------
Also I can import rospkg in python, but none of the other ros modules. Any idea what could be the problem?
Hi,
Let me add a small remark for all the people (including me) who have encountered problems building ROS Melodic with Python 3. It is possible to make ROS Melodic work with Python 3 via an "apt" command, without having to build all the ROS packages with Python 3. The procedure is detailed here : https://dhanoopbhaskar.com/blog/2020-05-07-working-with-python-3-in-ros-kinetic-or-melodic/ .
I have not yet completely checked the installation, but thanks to this one the ROS publisher / subscriber seems to be operational with rospy.
The only drawback is that it is necessary to reinstall all ROS Melodic packages; but it seems less risky than trying to build all ROS packages with Python 3.
Regards,
XV25

Thanks @drmaj this worked for me
Hello, I was successfully able to install ROS melodic with python3 on Jetson Nano. But there is one issue I am facing. So, I added
source ~/ros_catkin_ws/install/setup.bash in my bashrc file. Now all of my project packages are in another catkin workspace called pre_production. The issue is I am able to build pre_production workspace with ROS but now even I source devel/setup.bash, it is now taking that and I am not able to run any launch files for nodes from pre_production workspace. Any suggestions?
@metalglove But did you get python3 up and running with ROS Melodic?
My code have to run on the nano jetson and I believe there is no ros noetic installation for it, just Melodic.
So it's very important for me to get ROS Melodic up and running with python3
