Problem when calling netconvert in sumo:
I am trying to create my own scenario for simulation purposes.
I am using OpenStreetMaps for this.
python osmWebWizard.py
opens the browser and I select the area which I download.
netconvert --osm-files osm_bbox.osm.xml -o osm.net.xml
The error message I get is
Error: Cannot import network data without PROJ-Library. Please install packages proj before building sumo
Warning: Environment variable SUMO_HOME is not set, using built in type maps.
Quitting (on error).
My attempt to fix the problem is:
sudo apt-get install libproj*
But it seems like a dead end there and I am out of options.
Thank you.
EDIT
I have a gut feeling it has to do with libproj0 not being available anymore.

I am trying to use a repository I found on GitHub (https://github.com/AntonMu/TrainYourOwnYOLO) to train a YOLO model for a text detection application. However, when running one of the provided scripts to download and convert YOLO weights, I get the following errors screenshot of error message
I know that the issue is that I am missing libraries, however I am not having much success finding/downloading those libraries.
So far I have tried running:
sudo apt-get update
sudo apt install nvidia-cuda-toolkit
I have also tried running:
sudo find / -name 'libcudart.so*'
However, I am getting a 'Permission Denied' Message
I was going to try the advice listed on this blog: https://dominoc925.blogspot.com/2021/08/how-to-install-cuda-11-on-ubuntu-2004.html
However, I am very new to doing projects like this and am worried about running commands that will mess with my computer...is this a safe/correct solution?
If anybody could offer any other recommendations, I would greatly appreciate it. (OR if you know of any simpler methods of running YOLO on images tagged with VoTT) Thank you!
Check version TensorFlow, Cuda and Cudnn is correctly matching.

At first, I tried to fix my problem of npm instruction
so I added
[interop]
appendWindowsPath = false
to /etc/wsl.conf
It works, but another problem happen.
When I type code .
Command 'code' not found, did you mean:
command 'node' from deb nodejs (12.22.9~dfsg-1ubuntu3)
command 'cdde' from deb cdde (0.3.1-1build1)
command 'ode' from deb plotutils (2.6-11)
command 'tcode' from deb emboss (6.6.0+dfsg-11ubuntu1)
command 'cde' from deb cde (0.1+git9-g551e54d-1.2)
Try: sudo apt install <deb name>
The above Error message appear.
I tried the following instruction
export PATH=$PATH:"/mnt/c/Users/%USERNAME%/AppData/Local/Programs/Microsoft VS Code/bin"
It also works properly.
Whenever I restarted WSL, npm instruction still worked well, but code instruction lost its function again.
What should I do to fix the problem?
Thanks in advance!
My main suggestion would be to not use appendWindowsPath = false to fix your NPM problem. That's like using a sledgehammer as a flyswatter. As I said in this answer:
Please do not follow the recommendations (like this answer) to completely remove all Windows paths from WSL, as that will severely limit your ability to run Windows applications in WSL (one of its great features).
You'll also lose access to the ability to run PowerShell scripts and commands in WSL easily. You won't have direct access to wsl.exe itself from inside WSL (which comes in handy).
You can type the full paths to these commands, of course, but most instructions and other answers you find here are going to assume that you've left the Windows path intact.
Instead, figure out where npm is installed in your WSL distribution and then determine why it is further toward the end of the PATH than your Windows directories. Windows paths are added at the end of the Linux PATH for a reason. If something in your startup files is adding to the path, it should put it at the beginning, so it has precedence. E.g.:
export PATH="newdir:$PATH"
Note that I'm not saying that you should change your export statement above since, as mentioned, that Windows path would normally come at the end anyway. It's really not going to matter unless you put another code executable somewhere else in your path.
Whenever I restarted WSL, npm instruction still worked well, but code instruction lost its function again.
If you do want the "quick and dirty" (not recommended) solution, then you can simply add that export command that "makes it work" to your ~/.bashrc. That file is processed each time the Bash shell starts interactively.
I found this repo with a systemtap script for letting me use QWERTY ctrl-shortcuts on my dvorak layout. Unfortunately, I can't get it to work, but I don't think it has to do with the script itself. I'm running Pop OS and I think that it's because the linux-image I need with all the debug symbols doesn't exist.
The script says I need to install linux-headers-$(uname -r) linux-image-$(uname -r)-dbg
For me, this turns into linux-headers-5.11.0-7620-generic linux-image-5.11.0-7620-generic-dbg
linux-headers-5.11.0-7620-generic exists and I'm able to download it using apt-get.
linux-image-5.11.0-7620-generic-dbg can't be installed using apt-get. I can install
linux-image-5.11.0-7620-generic, but that's not the same thing. I've spent time looking online for it and adding different keys to apt-get, but I haven't been able to find anything with that name. If the problem is not having the correct linux-image package installed, I need help being pointed in the right direction as to where I can get it.
I tried following the directions here, and I've also searched this to no avail. I tried downloading and installing linux-image-4.4.0-142-generic-dbgsym_4.4.0-142.168_amd64.ddeb but that also didn't work.
If this isn't the problem, I've provided the output of the script. Any help is appreciated.

Tip: /usr/share/doc/systemtap/README.Debian should help you get started.
Yes, debuginfo downloading has been a pain on many distros. However, if you're running Debian kernels, see: https://wiki.debian.org/Debuginfod for instructions on using a new automated system. Generally: https://sourceware.org/elfutils/Debuginfod.html .
I'm new to Elm. and I'm not good at English. So, if any ambiguous or wrong thing is there, please let me correct it.
----------- edit -----------
All my problem below is on WSL. when I'm trying on windows, all work fine. then... why elm install doesn't work on WSL? did you have any idea?
-------- problem --------
when I try to elm-test init, it doesn't work like below
$ elm-test init
Here is my plan:
Add:
elm/random 1.0.0
elm-explorations/test 1.2.2
Would you like me to update your elm.json accordingly? [Y/n]:
-- PROBLEM DOWNLOADING PACKAGE -------------------------------------------------
I was trying to download the source code for elm/random 1.0.0, so I tried to
fetch:
https://github.com/elm/random/zipball/1.0.0/
But my HTTP library is giving me the following error message:

Are you somewhere with a slow internet connection? Or no internet? Does the link
I am trying to fetch work in your browser? Maybe the site is down? Does your
internet connection have a firewall that blocks certain domains? It is usually
something like that!
but my Browser(Chrome) is working beautifully, and even in WSL (the environment that I run elm-test init command at) is too.
$ curl https://github.com/elm/random/zipball/1.0.0/
https://codeload.github.com/elm/random/legacy.zip/1.0.0<body>You are being redirected.</body></html>
then I also try again to redirect the URL
$ curl https://codeload.github.com/elm/random/legacy.zip

I think there's no Network Problem. My PC can connect with the repo, and I think it will be downloaded well.
I lastly tried just elm install, and that throws the same error too. it seems like Elm can't connect with the repo, even if My PC can.
$ elm install elm/random
Here is my plan:
Add:
elm/random 1.0.0

I recently had reason to use WSL for elm development. It wasn't much fun and I'm glad to be back on Mac! What I found was that certain disk operations on WSL seemed to go very slowly and that could lead a variety of weird issues.
I was using Webstorm, which does not handle WSL well, so in the end I did everything on C: drive (rather than in /home/...) so that webstorm could run the windows version of elm-format, while my node development environment was run on the linux layer.
That's not a precise answer to your question but just to say that it can be done, but its not an ideal way to write Elm code in my experience
I had same issue and it was solved.
It was due to DNS server settings.
Create a file /etc/resolv.conf and write the following line.
nameserver 8.8.8.8
Then WSL will refer to Google Public DNS and works fine.
However, when restart WSL, the settings revert back.
Therefore, the following settings are also required.
Create a file /etc/wsl.conf and write the following line.
[network]
generateResolvConf = false
wsl --shutdown and restart WSL.

Error:
<PATH_TO_SUMO>/bin/netedit: symbol lookup error: /usr/lib/libgdal.so.20: undefined symbol: ecs_SetReportErrorFunction
This error appears when I try to run netedit. I have both the Webots simulation software, as well as the SUMO simulation software in my system and both, have netedit. When I remove either one of the software and then run netedit, it works. So, I think the issue is because of the presence of netedit twice. I was running netedit directly from the terminal but even after I give the exact path of the netedit I want to run, in a python script, and then run that script(For eg: I give the path of the netedit in SUMO), it shows this error. How to force the system to use a particular netedit (either webots' or SUMO's) whenever the netedit command is given?
This should be a question of setting your environment variable(s) PATH (and possibly LD_LIBRARY_PATH) to the correct values. If you install SUMO via the package manager of your Linux (apt or something) there should be nothing to adapt. I see from the Webots docs that they recommend manual adaption of those paths. If you don't do those changes or revert them you should be always using the netedit coming with plain SUMO. If you want to use the Webots version adapt the paths such that they list Webots directories first.
