You provide python example code here: https://ibm-public-cos.github.io/crs-docs/python
As part of this, a Linux user needs to either use the environment variables show on the page, or set up the file in ~/.aws to hold the aws keys.
What is the analog for Windows (assuming this works under Windows)?
You could try:
> dir "%UserProfile%\.aws"
Source: https://docs.aws.amazon.com/cli/latest/userguide/cli-config-files.html
Alternatively, if you follow the links from the link you provided younare taken to the boto3 s3 library which describes environment variables for setting your credentials: http://boto3.readthedocs.io/en/latest/guide/configuration.html
If you are on Windows, I would recommend one of two approaches:
1) Installing Cygwin which is the most popular way to get a bash shell on a Windows environment
2) Installing Ubuntu natively on your Windows machine. Starting with Windows 10, it is now possible to run a Linux kernel natively, inside
a Windows system [1][2]. This is also referred to as "Bash on Ubuntu on Windows". There is a very cool talk with a demo about this.
Alternatively, you could continue to live in a pure Windows environment and instead set up environment variables in Windows for your Python application.

I'm using wsl and it runs codes in vscode pretty fine and I have different libraries which I installed through pip and conda in wsl but when I run that code using vscode itself it doesn't recognize the libraries or even pip itself.
I don't have any other environment.
I should add that I installed the packages globally using conda install ... or pip install ... in base environment and I only have base environment and I run my code through code . and I also have python and remote wsl extensions installed in my vscode.
what can be the problem?
I don't have much personal experience with this, but I found some useful information in this Stack Overflow question (even though it doesn't utilize conda), along with https://code.visualstudio.com/docs/remote/wsl-tutorial#_python-development.
I also found this blog post useful, even if it doesn't cover WSL.
In short, make sure you:
Have installed the Python extension (by Microsoft) in VSCode. This is critical for being able to detect and select the Python interpreter. You don't mention having this in place, so I believe this is your likely problem.
You have done this already, but including it for others who might read this later -- Install the Remote - WSL extension (or the Remote Development extension pack) in VSCode.
You are also doing this already -- Start VSCode from inside your WSL distribution. Alternatively, you can start VSCode from Windows and then select the Remote WSL - Reopen Folder in WSL from the Command Palette (also accessible from the "Remote" Status Bar).
In VSCode, open the Command Palette with Shift+Ctrl+P, search for the Python: Select Interpreter command, and you should find your Conda environment in the list.
After selecting this, you should find that your project is using the interpreter and modules that you have installed via conda.
One thing I did to overcome this issue is go to Extensions -> Local (You should have two tabs there, Local and WSL:DISTRO) DISTRO refers to whatever DISTRO you're using, you will see that some of the local extensions are disabled in the current workspace (WSL) and there is a little cloud icon in the WSL:DISTRO tab that says install Local Extensions in WSL:DISTRO once you click that it will let you choose which extensions to install and you should be good to go!

I am referring to: Remote debug of Rust program in Visual Studio Code
My config is slightly different that is why I cannot get everything going here:
VScode installed on WIN32 with RUST components successfully!
remote system: odroid C2 ARM64 with UBUNTU18.04 with Kernel 5.14nwith IP: 192.xxx.6.x - user odroid.
I need to remote-compile a Rust program called: c2_mmap_gpio on the OdroidC2
This is already a project on the WIN32.
I did all the steps but it doesn't work.
I think it is not possible to try to run a remote_debug.sh (bash) on a windows machine, right? If yes workaround on this?
I think I need to input my user PWD somewhere to be able to ssh into the remote linux machine, right?
Correct, the remote_debug.sh I described in my answer is good only for a Linux system, and not suitable for a Windows system. For a Windows development system, you would need to write a Windows batch file or Powershell script that provides the equivalent functionality to that remote_debug.sh Bash script.
I'm not proficient in Powershell scripts, and I'm happy using Linux
as my host development machine, so I don't have plans to write such a script.
Regarding needing to enter a password for the SSH operations... Good point. That's something I didn't think to mention in my answer. You need to remove the need for a password to be entered, in one of two ways:
Install your public SSH credentials onto the target, using ssh-copy-id (or the Windows equivalent). Then you should be able to SSH to the target without needing to enter your password.
Give a blank password to the target user on the target, using passwd -d <username>. Note this reduces security, so this is not recommended, especially if the target is accessible via the public Internet.
I want to install VS Code + some extensions (Java to be exact) on the PCs (CentOS) in our university lab. I installed the editor itself according to the official documentation, but I'm running into problems when I want to install extensions. I'm logging into the systems as root via ssh.
Running sudo code --install-extension vscjava.vscode-java-pack --user-data-dir /some/dir (source) runs successfully, and the extensions are available when VS Code runs as root. The problem is: When I start VS Code as another user, the extensions are not installed.
My questions are:
What is stored in the user-data-dir? Does it contain the location of the extensions-dir? If yes, is it wise to share it across all users of the system?
What is the recommended way to install extensions system wide for different users?
Thanks!
I also need to be able to install extensions systemwide, but there doesn't seem to be a way to do this. The best solution I've found is to write a batch file that installs the extensions and then starts VS Code. I have users run that scr
I'm using the fantastic SageMath Cloud service to remotely collaborate with a partner. In particular, I'm using IPython notebooks. Unfortunately, the language seems to default to Python 2; I would prefer Python 3.
SSH'ing into my project, I can see that IPython 3 is actually installed. Is there a way to coerce SMC into using Python 3 for notebooks?
I have tried the instructions mentioned in the FAQ, i.e.,
ln -s /usr/bin/python3 ~/bin/python
ln -s /usr/bin/ipython3 ~/bin/ipython
While this works for invoking Python from the SSH commandline, it doesn't seem to affect the kernel used by IPython notebooks created from the web GUI.
Once you open an IPython Notebook on SageMathCloud you can switch the kernel to a variety of choices, including Python 3. To do that, use the 'Kernel' menu, then 'Change kernel', then 'Python 3'.
Switching to the Python 3 kernel in the IPython Notebook on SageMathCloud is discussed in this discussion the sage-cloud mailing list.
Is this what your question is about, or are you asking how to make that choice the default when you open a new IPython Notebook on SageMathCloud?

is there a posibility to make eclipse PyDev use a remote Python interpreter?
I would like to do this, as the Linux Server I want to connect to has several optimization solvers (CPLEX, GUROBI etc.) running, that my script uses.
Currently I use eclipse locally to write the scripts, then copy all the files to the remote machine, log in using ssh and execute the scripts there with "python script.py".
Instead I hope to click the "run" button and just have everything executed within my eclipse IDE.
Thanks
Unfortunately no. You can remotely connect to your Linux server via Remote System Explorer (RSE). But can't use it as a remote interpreter. I use Pycharm. You can use the free Community Edition or the Professional Edition for which you have to pay for it. It is not that expensive and it has been working great for me.
As Adel says, this is probably not possible with the Remote System Explorer, or the normal Run button,
but you can automate the process you currently use. I had to do this for a few weeks when the fan was broken
in my laptop, and doing any significant computation there made it overheat and poweroff, so I just ran
everything on my work machine.
You can use the External Tools mechanism to run a short script that syncs your code to the remote server,
runs your script, then syncs back any output files to your local machine. My script looks like this,
is stored in $HOME/bin/runremote.sh, and is executable (chmod +x runremote.sh)
fp="$1" # Local path to the script we want to run--for now,
# this is the only command I pass in from Eclipse, but you could add others if so inclined.
# My home directory is a little different on my local machine than on the remote,
# but otherwise things are in the same place. Adjust as needed.
fp=`python -c "print '$fp'.replace('/home/tsbertalan', '/home/oakridge/bertalan')"`
# Run the synchronization. I use Unison, but you could use something else,
# like two calls to rsync, or a series of scp commands.
reposync >/dev/null # The redirection assumes your sync command will print errors properly on stderr.
cd='cd '`dirname $fp`
# I use a virtual environment on the remote server, since I don't have root access to install
# packages globally. But this could be any set-up command you want to run on the remote.
# A good alternative would be `source $HOME/.profile` or `~/.bashrc`.
act='source /home/oakridge/bertalan/bin/activate'
fname="`basename $fp`"
cmd="$act ; $cd ; python $fname"
# Run the command remotely. The -X forwards X11 windows, so you can see your Matplotlib plots.
# One difficulty with this method is that you might not see all your output just as it is created.
ssh bertalan#remote.server.edu -X "$cmd"
sleep 1
# My synchronization script is bidirectional, but you could just use rsync with the arguments flipped.
reposync >/dev/null
If you don't use linux or OSX locally, you'll probably have to use MinGW or Cygwin or whatever to get
this working. Or, since you appear to have a working Python interpreter, you could write an
equivalent script in Python, make it executable (by the file properties dialog in Explorer, I think),
and add a #!/path/to/python line at the top. I don't use Windows regularly, so I can't really help with that.
To use this in Eclipse, go to Run > External Tools > External Tools Configurations.... Add a new tools
whose Location is the path to your script, and whose first Argument is ${resource_loc}.
You can then use it with Run > External Tools > [first item], or bind it to a keyboard shortcut (I used F12)
by going to Windows > Preferences > Keys, and searching for "Run Last Launched External Tool". Presumably you'll
have to go through the menus first to make this the "Last Launched" external tool.
