Not attaching to xonsh installation #2

Hmm, it should work with IPython 4, is it listed under |
|
No it isn't...

What version of xonsh are you on? |

I just released a new version, please try |

Awfully sorry guys - I figured out it was due to the xonsh program at I installed I ran ... the bad news is there are now 2, one seemingly installed via
Sorry if I've gone about this the wrong way. I was getting /usr/bin/env: python -u: No such file or directoryso I rewrote the #!/usr/bin/env sh
export PYTHONUNBUFFERED="XONSH_SET"
/usr/bin/env python -c "from xonsh.main import main; main()"and solved this issue. The kernel still doesn't work though so I'll leave the logs above in case they help debug the issue. |

Does it work if you: |
|
@blink1073: No change there unfortunately |
|
Bummer, I'm afraid I'm out of ideas on this one. |
|
I get the same as @lmmx, both with using xonsh and xonsh_kernel as the kernel. |
|
There is more discussion of the fix at xonsh/xonsh#565, which I think just needs to be cleaned up to provide a |

Cheers, I still get this problem even with PYTHONUNBUFFERED set - I get no response from the "xonsh" kernel, while the "xonsh_kernel" kernel gives me the error in the TypeError referenced in the first post. An interesting thing to note is that when when I use the "xonsh" kernel, i while I get very high CPU usage: effectively one CPU fully utilised. When I look at whats using it, it is a bash process, running a scrip that I think is created by foreign_shells.py, at least it starts: When I kill jupyter, this continues to run, one of these had been running for 18 hours before I caught it. |

Hi @IanSudbery, Ok can you try a couple of things then please? The first is to see if we can get this to stop by not loading bash. Set the foreign shells section of your config file (~/.local/config/xonsh/config.json) to empty: {"foreign_shells": []}Does the high-cpu Bash process still get spawned? The second thing to try is to turn off the safety and have bash throw an exception. For this, set you config file to: {"foreign_shells": [
{"shell": "bash", "safe": false}
]
}Does this throw an error, and if so, what? Note that these can be separate files that you pass in at the command line via |

Hi @scopatz, Thanks for your help. If I set foriegn_shells to empty, then I don't get the high CPU Bash process. The kernel sort of works... In python mode, I can type python and get responses. However, in subprocess mode, the output goes to the terminal I started jupyter from rather than to the notebook. At this point, I have lost control of the terminal ^C, ^Z do nothing and I have to kill the juptyer process from elsewhere. If I set bash to unsafe, I get the same as before ... no response at all from the kernel and a high-cpu Bash process. |
|
@IanSudbery - OK, some progress at least. What version of jupyter are you using? |
|
@scopatz -jupyter 4.0.6 |
|
Hmmm OK. I am seeing this issue now too. |
|
This should be fixed on master xonsh now. |
|
I can't verify, because I could not reproduce, I'll wait for @IanSudbery or @lmmx to chime in. |
|
Sorry, I've been away, I'll try to test this out today. |
|
Works great now from both Xonsh master and here. |
|
Great, thanks, closing as fixed. |
I installed with
pip install xonsh_kernelon IPython 4.0, Python 3.5 (Anaconda on Linux Mint)pip show xonsh-kernelsays it's installed:But no entry in
~/.local/share/jupyter/kernels(wherematlab_kernelwent for example) nor in~/.ipython/kernelsnor in/usr/local/share/jupyter/kernels, and so no entry in the 'select kernel' menu item, and "No such kernel error" when I runipython qtconsole --kernel=xonsh_kernelHave I missed something obvious here or is this a work in progress..? Or perhaps not compatible with IPython 4 yet ?
