I'm on an arch linux machine and trying to compile anki from source, despite following the instructions, I seem to get the following error no matter what I do:

Just for testing purposes, I wrote a dockerfile which tries to build anki in an isolated environment. This works without issues. (Here's the dockerfile)
I verified that I have all the dependencies from the dockerfile installed on my main machine, but I still get the same error.
I also tried clearing the bazel cache without any success.
Please confirm if you have followed these steps
Install Xubuntu (xubuntu-20.04.3-desktop-amd64.iso) into a new VM.
Install VirtualBox Guest Additions and the automatic Xubuntu updates.
Install these packages and bazel according to linux.md.
Kindly refer to this document on how to build Anki from source.Thank you!

I was working along in Python in Visual Studio code 1.73.1 on my Mac (OS 11.6, Python 3.9), and after successfully starting a debug session more than 30 times, suddenly it wouldn't. I tried several times. Shortly I noticed this message: "the isort server has crashed 3 times in 5 minutes. It will not be restarted." Clicking through, I discovered the existence of the isort extension and began trying solutions:
Turn off the isort extension. Result: the little horizontal progress line in the upper left corner moves for about half a second and then vanishes. No command appears in the terminal. The same result follows the next several steps:
Delete the extension.
Replace it with a competing isort from someone else.
Replace the Python extension with a more trusted version as described here:
https://learn.microsoft.com/en-us/answers/questions/724858/vscode-debugger-not-working-for-python.html
Uninstall and re-download Visual Studio code.
At last I really went all the way:
Trash the application and empty the trash.
Delete all relevant files as listed here [https://stackoverflow.com/questions/42603103/how-to-completely-uninstall-vs-code-on-mac] :
rm -fr ~/Library/Preferences/com.microsoft.VSCode.helper.plist
rm -fr ~/Library/Preferences/com.microsoft.VSCode.plist
rm -fr ~/Library/Caches/com.microsoft.VSCode
rm -fr ~/Library/Caches/com.microsoft.VSCode.ShipIt/
rm -fr ~/Library/Application\ Support/Code/
rm -fr ~/Library/Saved\ Application\ State/com.microsoft.VSCode.savedState/
rm -fr ~/.vscode/
Reinstall Visual Studio code. This got me back to the place where, while failing to start a debug session, it said "the isort server has crashed 3 times in 5 minutes. It will not be restarted." (How do you clear that flag so that it will try again, anyway?)
It would seem that VSCode debugging has been wrecked by an automatic update to something else that is not actually part of VSCode. Has anyone seen this? Is this a known problem that could be fixed by installing a different version of something?

I don't know how to fix this bug,Can someone help me?thanks
From the verbose output, you can see that the command C:/Users/moush/AppData/Local/Microsoft/WindowsApps/python3.exe E:/work_space/Technology_related/V88888/v8/build/vs_toolchain.py get_toolchain_dir failed. You can try running that on its own to see if it reports any additional details, which might help you figure out what's wrong and how to fix it.
From the fact that "it failed" alone, I would guess that it somehow didn't detect your Visual Studio and/or Windows SDK installation. FWIW, the official instructions how to install VS are here (linked from the V8 docs). It looks like your SDK might simply be too old.
You can also try the convenience workflow based on tools/dev/gm.py to see if that avoids this issue, but I'd guess that it will probably run into the same problem.
https://raw.githubusercontent.com/paramiko/paramiko/master/demos/demo_server.py
I see the above demo_server of paramiko. But I don't see the instructions on how to run it. I run the following ./demo_server.py command. But once I run ssh robey#127.0.0.1 -p 2200, the server fails. Could anybody let me know the complete steps on how to run this example? Thanks.

I managed to get it to work, make sure to go through these steps (Thank you Sandeep for the pip insight), chances are you may be missing the Kerberos dependencies:
You may need to perform pip install gssapi in the CLI if that has not already been done (I'm using the Windows Command Prompt, Linux/WSL might need pip3 instead depending on your version of python)
From there you will need to import the gssapi library into the code at the top with the other imported libraries, so just call
import gssapi in demo_server.py
After running demo_server.py again, the CLI should eventually say something like it is missing files located in Program Files\ MIT\ Kerberos\ bin, as Kerberos is a dependency for gssapi, you can install it from here:
https://web.mit.edu/KERBEROS/dist/
Make sure you do custom install if you're not sure where it will be downloaded, so that you can set up the file location where the CLI says is missing in step 3 (Should automatically say Program Files\ MIT). I unchecked the boxes for auto-start and tickets, but not sure as to what your preferences may be. After all that, a computer restart is required.
I am attempting to build tensorflow from source with MKL optimizations on an Intel CPU setup. I have followed the official instructions here up until the command bazel build --config=mkl --config=opt //tensorflow/tools/pip_package:build_pip_package.
Unfortunately, the compilation runs for some period of time and then fails. I'd appreciate any help with this matter.
Updated Output log (using bazel --verbose_failures):

This appears to be a problem with Tensorflow 1.10 build. I recommend you check out the r1.9 branch as it builds totally fine. Either the dependency list needs to be updated or Tensorflow will fix this. If you are determined to run the r.1.10 api then run the following in terminal:
pip install keras_applications==1.0.4 --no-deps
pip install keras_preprocessing==1.0.2 --no-deps
pip install h5py==2.8.0
If you're just interested in the release version (git tag will show you all available releases), run git checkout v1.10.1 before the ./configure step. Then you can follow the official instructions without installing additional dependencies.
Currently, a master branch build will give me the following error in Keras code that worked previously (this is after calling model.fit_generator() from the stand alone version of Keras):
`steps_per_epoch=None` is only valid for a generator based on the `keras.utils.Sequence` class. Please specify `steps_per_epoch` or use the `keras.utils.Sequence` class.
Builds based on the 1.10.1 release version of TensorFlow don't cause this error.
I have a client-side post-receive git hook that runs a Python script. The script uses GitPython to do a diff between HEAD and HEAD~1, figure out the names of files that have been changed, and then compose a tweet that updates followers about the change.
The hook itself is just a shell script that runs python wikitweet.py, where the Python script does the heavy lifting.
When I run the Python script on the remote side after a push, everything works fine. But when I push from the local side, I get the following error:
remote: Traceback (most recent call last):
remote: File "/home/wcm1/bin/wikitweet.py", line 21, in <module>
remote: most_recent_diff = repo.head.commit.diff('HEAD~1')

remote: stderr: 'usage: git diff [--no-index] <path> <path>
remote: '
After which the push to master and update of working of copy completes just fine. I can tell from the commit hash in that error message that the script is successfully getting the new HEAD commit, so it doesn't seem to be an issue (I don't think) of when the hook is being run.
I'm guessing that I'm either misunderstanding hooks, or doing something wrong in my Python script, but am having difficulty understanding why it runs on the remote side but fails after push. Here are the relevant lines in wikitweet.py that seem to be causing problems:
repo = git.Repo('/path/to/repo')
most_recent_diff = repo.head.commit.diff('HEAD~1')
changed_files = []
for x in most_recent_diff:
if x.a_blob.path not in changed_files:
changed_files.append(x.a_blob.path)
if x.b_blob is not None and x.b_blob.path not in changed_files:
changed_files.append(x.b_blob.path)
[...]
I also have different versions of Python running on remote and local, though I don't see why that would cause a problem.
