Visidata: "could not find terminal" in pycharm python console when using vd.view_pandas(df)

[manihamidi]

Small description

love the vd.view_pandas(df) functionality and works perfectly in iPython, however there seems to be a slight incompatibility with the pycharm python console.

Actual result with screenshot

import visidata as vd
vd.view_pandas(df)
Traceback (most recent call last):

    setupterm(term=_os.environ.get("TERM", "unknown"),
_curses.error: setupterm: could not find terminal

Additional context

• The "use iPython when available" box is checked in Settings > Build, Execution, Deployment > Console panel.
• Information provided by the pycharm python console at the very top when you open it:

Python 3.8.3 (default, Jun 24 2020, 18:02:19) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.16.1 -- An enhanced Interactive Python. Type '?' for help.
PyDev console: using IPython 7.16.1

• vd version: 1.5.2

Any tips on how to solve would be appreciated!

Hi @manihamidi, I don't have a pycharm setup so it's going to be difficult to debug given only this information. Is this on Windows?

[anjakefala]

It seems like this is more related to how PyCharm interfaces with curses, than with VisiData specifically!

Some potentially helpful things to try are here: https://stackoverflow.com/questions/9485699/setupterm-could-not-find-terminal-in-python-program-using-curses

hey @saulpw , no i'm running pycharm on ubuntu 18. I'm getting by using the pycharm terminal to run ipython and then visidata. It's not ideal but ok for now..

[manihamidi]

thanks for the link @anjakefala . Tried setting the envvar and now i get a different error!

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

which seems to be addressed here: https://stackoverflow.com/questions/52747655/why-do-i-get-curses-error-cbreak-returned-err-when-using-tensorflow-cli-de

Not sure how that solution translates to curses/vd.. any ideas?

[anjakefala]

cbreak would return ERR if you run a curses application that is not on a real terminal

Did you follow these steps?

hit menu Run then Edit configurations...
select the configuration corresponding to your project
check the checkbox Emulate terminal in output console

I basically have no idea, and I am also using google to find these things. =( I hope you figure it out!

I am going to close this issue because I do not think the problem is on our end, but please continue using it as a space to debug your problems with us. It may help somebody else who faces a similar issue down the line.

hmm... thanks that's potentially helpful, but those configurations are for python consoles that launch when you "run" a particular python module, not the interactive (iPython) console. Couldn't find a similar checkbox for the interactive console yet.

anyways thanks... submitted a ticket to pycharm, hopefully that'll help resolve the issue.

FYI for future readers: PyCharm support said:

Unfortunately, PyCharm doesn't support curses at the moment. Please feel free to submit a feature request about it to our issue tracker using the link https://youtrack.jetbrains.com/issues/PY
