Spyder: Enter inserts new line instead of executing the command

Created on 1 Feb 2018 · 26Comments · Source: spyder-ide/spyder

Hi,
I have been confronted to this issue for the last few days after updating anaconda. After some time using Spyder the console would not behave as expected: pressing enter creates a new line instead of executing the command. Pressing shift+enter executes it but extremely slowly ( "2+2" takes ten seconds)

I cannot reproduce this behaviour on demand. It happens after some time, first I had the impression that large dataset and pasting in the console were likely triggers, but it also happens when I am not in this case...

I tried to downgrade spyder, qt, ... with no effect. This morning I uninstalled anaconda and installed it back again, and the bug persists.

This is my first message here, so sorry if I am not being clear.
Thanks a lot for your help
Pierre

I noticed that whenever I am working with a large dataframe, I need to shift+Enter to execute the statement

Thanks for reporting @s2raf. I also noticed this problem but I don't know where it comes from. We'll try to fix to it in a future release.

As another data point, occasionally, I've noticed enter inserting a line break rather than executing the statement (but with no real temporal pattern or particular functions that I noticed), and separately there are a few specific functions that would make the console hang on open/close parens (due to introspection encountering some huge data structure), but while I've had Spyder open for many days at a time with on and off use throughout, I don't think I've noticed both happening together as you describe, at least on Windows.

@Prikers, did you disable tooltips in our consoles?

ccordoba12 on 2 Feb 2018

@ccordoba12, nope, forgot about that. I will try that next time I have a large dataframe to work with (this was only for ~20Gb dataframes)

Prikers on 4 Feb 2018

Apparently my "problem" is gone. It disappeared after reseting Spyder, which I did not do before opening this issue, even though I reinstalled anaconda.

After executing "spyder --reset", everything seems to work OK, I've not bumped into that bug for the last 4 days.

Good to know! However, I'm still able to reproduce it.

ccordoba12 on 5 Feb 2018

It's back. And Spyder crashed while trying to open a new console.
Today I installed and used new packages and ther dependencies (pillow, scikit-image). It occurred when I switched from inline to macOSX backends, but have no idea if it is related...

Recently observed this exact behavior. Spyder 3.2.7 Python 3.6.3. Appeared only for large dataframes. Calling the data frame in the console to print it would often work, but calling df.head() would start a newline and give ...: as if I had forgotten a parenthesis. With smaller dataframes this behavior would occur inconsistently. A command might cause it but the same command 30 seconds later would not.

@jmdata86, to avoid this problem please go to

Preferences > IPython console > Display

and deactivate the option called

Display balloon tips

The problem is the kernel gets stuck getting calltips for large dataframes, and that's what causes the new line problem.

Hello,

I also have their problem, even when I am not working with large dataframes.
It even happens when I check the length of an (small) array.

alexfilothodoros on 14 May 2018

@morsanimi And what happened when you tried the workaround posted immediately above your comment?

CAM-Gerlach on 15 May 2018

It happens less often.

alexfilothodoros on 17 May 2018

Hi,
the issue is back (even with ballon tips deactivated). The issue appears after the 2nd or third command ("import ..." or "2+2"). It is not related to large dataframes as I do not even have time to load anything.
Python 3.6.6
IPython 7.0.1
Spyder 3.3.1

Thanks for your help,
Pierre

@s2raf Sorry its come back. Can you paste your dependency output again? Was anything changed, added or updated before it stopped working? I tried it with Win 8.1 x64, Spyder 3.3.1, Python 3.6.6, Qt/PyQt 5.9.2/6, and IPython 7.0.1 even with 5-6 lines multiple times, and have never seen the problem.

CAM-Gerlach on 31 Oct 2018

I've seen this myself and I think this is an issue with the latest IPython and/or ipykernel. Please try to downgrade to IPython 6.5.0 and ipykernel 4.8.2 and try again.

ccordoba12 on 31 Oct 2018

Hmm. I tested on ipython 6.5.0 + ipykernel 4.8.2, as well as on ipython 7.0.1 + ipykernel 5.1.0 (in an environment just updated with conda update --all) on Python 3.6.6 and 3.6.7, and was unable to reproduce the problem even after a dozen varied commands each and doing dataframe-related stuff.

CAM-Gerlach on 31 Oct 2018

Happening to me, very regularly, every session. Tried the "Automatic" backend, and disabling balloon tips. Still there.

macOS 10.14.2
Anaconda (relatively new install -- 1 week ago)
Spyder 3.3.2
Python 3.7.1
IPython 7.2.0

chafer31415 on 17 Jan 2019

@chafer31415 This might be related to #2902 . Can you try conda install ipykernel=4?

CAM-Gerlach on 17 Jan 2019

Ok, yes. _Much_ better after conda install ipykernel=4. I was about to write "totally" fixed, but then it did happen once, though gently -- meaning the kernel came back after one extra ... line, rather than many extra lines. Still, though, much good was done with this fix, so my problem is clearly related to #2902. Thanks for the help!

chafer31415 on 17 Jan 2019

@chafer31415, you also need to update qtconsole (with conda update qtconsole) to avoid the extra ... that appears sometimes.

ccordoba12 on 17 Jan 2019

Yes, I executed conda update qtconsole and that seems to have cured the problem entirely. Thank you so much for your advice.

chafer31415 on 18 Jan 2019

Closing because this was fixed in Qtconsole version 4.4.3.

ccordoba12 on 21 Feb 2019

I'm also having this problem, on Spyder 3.3.3, Python 3.7. I've had this issue with multiple releases of Spyder on two different machines going back months now, I usually just get frustrated and give up. I now have no alternative to Python however, and really need this issue fixed as doing any actual work has become next to impossible.

I've tried all of the above (resetting Spyder, updating ipykernel, updating qtconsole, disabled 'display balloon tips' in Preferences) but nothing seems to work. Has a fix to this problem been found?

gsarrouh on 22 Jul 2019

See issue #2902.

I have the same issue not related to MacOS, My SSOO is windows 10.
