I want to learn Ros2, I have tried to install ubuntu and win 10 but both failed to recognize my RTX 3050. I tried running a virtual machine and it didn't get any better. I don't know if I can install Ros2 on Win 11. Please help me
I just successfully installed ros 2 (galactic) on windows 11 (in so far as I am able to run the demo_nodes_cpp talker and listener).
I initially tried following instructions on the official page and ran into a number of unclear issues (command not found, python version issues etc.) that felt like it was going to be a waste of time, until I went through that alternative:
https://ms-iot.github.io/ROSOnWindows/GettingStarted/SetupRos2.html
It was surprisingly painless.

I installed .net6 but i need to have installed .net5
So, I removed .net6 and I installed .net5.
Now, when I run 'dotnet build' command I have the error:
A fatal error occurred. The folder [/usr/lib/dotnet/dotnet6-6.0.108/host/fxr] does not exist
Do you have some idea to help me, please.
Thanks
.NET 5 has reached its End of Life. If you are using it, you are on your own; don't expect any fixes for security issues that discovered every few weeks.
Anyway, sounds like you are using Ubuntu 22.04.
If so, you are out of luck. There's no simple way to install or run .NET 5 there. .NET 5 needs OpenSSL 1.0 or 1.1. Ubuntu 22.04 only has OpenSSL 3.0. Even if you install and manage to run .NET 5, it wont work and you will get OpenSSL errors.
Your best course of action is to install an older version of Ubuntu, such as 20.04.
Your specific error in this case is quite unrelated to above, though. Your error is because you seem to have installed some packages from Ubuntu's package repository and some packages from Microsoft's package repository. See https://github.com/dotnet/core/issues/7699#issuecomment-1222470580 for details. In particular you want to follow the steps in "Mixed state scenario 2: Use PMC packages after installing native Jammy packages". But that's not needed on Ubuntu 20.04 or similar OS that you need to make .NET 5 work at all.
I am following instructions to teach myself qiskit (Quantum computing developer Kit) from https://qiskit.org/documentation/getting_started.html, which requires Anaconda 3. For this learning exercise I plan to use a RPi4 running Ubuntu 21.X on it. I installed 64-Bit (AWS Graviton2 / ARM64) Installer (413 M). The installation hit a block when at the prompt to initialize conda , I get an error: line 477: 5128 Illegal instruction $PREFIX/bin/conda init which is further described as an open issue here on GitHub.
Would like to know if anyone have had success with Anaconda on RPi4b and even better, have been able to use qiskit on any OS. [I see the mambaforge / mini forge options but I am not sure qiskit is going to be compatible for conda versions provided by mamba/miniforge.]
Thank you.
You can't use Anaconda installer on RPi4 as it was compiled for AWS Graviton2 architecture.
Have you tried miniforge? It should work fine on RPi4
When I try to run Rstudio Desktop (1.4) on my virtual machine (Ubuntu 16.4), Rstudio crashes and gives the error:
ERROR:gl_surface_glx_gt.cpp(141) GLX 1.3 or later is required.
I tried to follow the instructions on this page: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround, but can not get past the meson -D configuration in the Ubuntu terminal. At this point I get the error message: 'ERROR: Problem encountered: gallium-xlib conflicts with any dri driver'
I googled and tried everything that I could possibly find (similar questions as https://community.rstudio.com/t/x2go-and-rstudio/29704/2), but no success yet.
Obviously the upgrade to a higher GLX version is the cause, but I can not upgrade it.
Is anyone familiar with the error and what is actually causing it?
Any help would be greatly appreciated!
I am using R version 3.4.4
I am installing anaconda 2020.02 on a windows 10 machine. Everything runs smoothly until the installation gets stuck at:
Extract anaconda-2020.02-py37_0.tar.bz2
.
I have tried the installation several times (removing all files relating to the installation every time) and the same thing happens always.
Can anyone help me?
Thanks.
This question was asked 5 days ago by someone else but no explicit solution was given:
Anaconda installation get stuck at extract: anaconda-2020.02-py37_0.tar.bz2?
I had the same problem. My installer was stuck for hours at a time. So, I went to Anaconda's repo https://repo.continuum.io/archive/ and installed the immediately previous version 2019.10 and it installed just fine.
I know that by using virtual box, graphics card cannot be utilized by all the measures so I think it is not possible but I also think that coding cuda at least setting the CUDA developing environment is easier at Windows (unfortunately) thus if it is possible I plan to setup win8 to virtual box on my Ubuntu.
I do want to use win since I am at optimus Nvidia machine thus there is a driver problem at Ubuntu. In addition compilation of the code at Eclipse does not work due to that driver flaw. In case I use Win there might be the remedy of the problem.
Even if you get success in setting up environment in your virtual box to compile cuda code and you compiled cuda code there it will be of no use because you wont be able to run the code in virtual box.
Yes, your are absolutely right that installing drivers on optimus nvidia card is difficult task. I was also stuck with the same problem. but with release of cuda 5, installing cuda on Ubuntu is very simple.
follow these simple steps.
Driver installation ##
Download cuda 5 from here.(32bit or 64bit depending on OS)
Cuda 5 download
Install required tools by following command
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev
Next, blacklist the unnecessary modules
sudo gedit /etc/modprobe.d/blacklist.conf
add following lines at last
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
and reboot your system.
After reboot press Ctrl+Alt+F1. Login there and enter following command.
service lightdm stop
Go to location where you have downloaded cuda 5. In my case its on desktop.
cd Desktop
make it run from shell
chmod +x cuda_5.3.35_linux*****
Run from terminal
./cuda_5.3.35_linux*****
accept it, when asked to install drivers press y and n for cudatoolkit and gpucomputingsdk
now reboot and you are done with driver installation.
To install cudatoolkit and gpucomputingsdk follow this link
