Please start Spyder in a terminal (cmd.exe) and report back any errors you're seeing there.

[pj1989]

Unfortunately spyder.exe (in anaconda3\Scripts\spyder.exe) does not run in cmd.

However it does run in conda prompt.

If I run it in conda prompt I can reproduce the error, but no error message is generated. It just goes to a new terminal line like I just closed the program

[ccordoba12]

Sorry but without an error message is not possible for us to help you. My only recommendation is for you to update DirectX and your graphics card drivers. That could help.

[pj1989]

I understand that without an error message is difficult to make a diagnosis.

Nonetheless such behavior is clearly a bug and don't agree that ignoring it is the correct thing to do. I can perform more tests if you have any suggestion and digging around, maybe there's an error message or a log somewhere.

Unfortunately my knowledge of Spyder/conda is limited and I can't do it myself.

[ccordoba12]

I can perform more tests if you have any suggestion

That's the problem, I have almost no more suggestions. My last one is try to downgrade Qt with by running these commands in the Anaconda prompt

conda install qt=5.6 pyqt=5.6

maybe there's an error message or a log somewhere.

There are none, as far as I'm aware. And nobody else has reported an error like yours before. So we're even more in the dark.

[ccordoba12]

@CAM-Gerlach, I don't know if you want to chime in to help @pj1989 here.

[pj1989]

@ccordoba12 Unfortunatelly I downgraded Qt with the command you told me, but the problem still occurs

[ccordoba12]

Ok, @CAM-Gerlach has more experience dealing with this kind of problems, so let's wait for he to give you more advice.

[CAM-Gerlach]

@pj1989 I'm baffled; maybe some edge case in your graphics stack. I cannot reproduce the problem on Win 8.1 Pro x64 with the same versions of Python, Qt, PyQt, and Spyder. We've had reported issues in the past (which I was able to reproduce at the time) with autocompletion/help/introspection/real-time analysis crashing in the past when the user locked the screen or put to computer to sleep, but I can't recall a specific instance where that happened with Spyder itself. I seem to distantly remember someone reporting somewhere about something similar happening with the lock screen, but I can't seem to find it anywhere.

Since you've already tried the most likely fix (downgrading Qt), you should upgrade it again with conda update qt pyqt and then try the following potential steps that have a chance of resolving this particular issue. Before you do, run set SPYDER_DEBUG=3 in Anaconda prompt to enable debug output for Spyder. If none of the above work, copy and paste any messages that look like errors, as well as the last 20 lines or so before them (or just the last 20 lines, if there are no obvious error messages) here inside a literal block (with triple backticks, ```, above and below it). Then, try each of the following in order, stopping if one of them fixes the issue:

1. Temporarily disable any security, antivirus, firewall, etc. software and try again
2. Install PyOpenGL with conda install pyopengl
3. Update your OS and any graphics/GPU drivers
4. If you have multiple GPU (e.g. integrated + discrete), try disabling/forcing one or the other
5. Run spyder --reset, just in case. If you value your preferences (e.g. a custom syntax theme or shortcuts), make a copy of the spyder-py3 directory in your user/home folder and restore if it resetting fails to fix the issue.
6. Create a new, clean conda environment, and see if the problem still persists:

conda create -n spyder-env -c defaults spyder=3 python=3.6
conda activate spyder-env
spyder

If that does work while previous steps have failed, provide me the output of conda list to see if I can spot an obvious culprit. Otherwise, try doing a clean uninstall and reinstall of Anaconda. Thanks, and hope this works.

[pj1989]

@CAM-Gerlach
Few updates. I followed the instructions at point 2. 3. 4. 5. and 6. Unfortunately, being a work PC, I cannot disable the antivirus as it's locked by IT.

Unfortunately the problem seems to persist and I could not find any obvious error message in the console, even with SPYDER_DEBUG set to 3.

The problem seems to occur only when I lock the PC with the WIN+L keys combination, while it doesn't occur if I lock it from Start>[User]>Lock

I'm now going to perform a clean Anaconda installation.

What I did not mention in the original post, is that I received this PC brand new from IT just 10 days ago. The number of rubbish on it should be very limited and I did not install any strange software that customize the Windows environment any-how.

Anyway... below is a copy of the full output on the terminal from the activation of the environment, up to the crash. I cannot honestly find anything anomalous in it, but you know probably better than me what should and what should not be there.

I'll proceed now with a clean uninstall and reinstall of Anaconda and see if this solve the mystery...

HERE I PRESSED WIN+L. When I logged in back (2 seconds after) Spyder wasn't open anymore.
All I found in the console below the above lines is:

(spyder-env) C:\Users\Luca.amerio>

[CAM-Gerlach]

Sorry all that didn't fix it for you, and hopefully reinstallation does. I can't find anything suspicious in that output either, so I'm not sure why its happening other than being a security software issue or a conflict with something else.

Unfortunately, being a work PC, I cannot disable the antivirus as it's locked by IT.

Then tell IT it may be falsely causing a problem with one of the programs vital to your work, and they can do it themselves. If it resolves the problem, then they can add an appropriate exclusion/exception/rule for Spyder.

The problem seems to occur only when I lock the PC with the WIN+L keys combination, while it doesn't occur if I lock it from Start>[User]>Lock

That's really strange, and I have no idea what's causing that difference in behavior. If you can't resolve it any other way, maybe try using AHK or something to bind a hotkey to Start > User > Lock?

[pj1989]

@CAM-Gerlach
Neither the clean installation worked.
At this point I'm completely roaming in the dark.

Thank you for the help. I'll keep you posted just in case I find a culprit.

[CAM-Gerlach]

@pj1989 Sorry that didn't work. In the meantime, I recommend just binding a hotkey or other shortcut to that command instead.

The only thing I can think of is your AV, firewall, or other security software is causing issues. I recommend speaking to your IT department about it, since they have much more control over whatever is happening than Spyder (we can't actually crash Python like that from within Spyder; it would have to be at the Qt/C++ level). Again, sorry about this.

[ccordoba12]

Closing because there's no more we can do about this.

[pj1989]

The culprit ended up being a faulty Wacom driver service called: _Wacom Tablet Service for ISD_

Disabling that solved the issue. The fun part is that I don't use touch-screen features, nor have a Wacom tablet. Nonetheless, this solved the issue.

Sorry for bothering you for this issue. The first thing I obviously thought of was a problem with spyder, but this ended up being completely innocent.

Thank you for the support
Luca

[ccordoba12]

Glad you found the culprit and thanks for letting us know about it.

I guess you fought a lot to finally uncover the real cause.

[jsh9]

I just encountered the same issue.

Spyder 3.3.3 | Python 3.7.3 64-bit | Qt 5.9.6 | PyQt5 5.9.2 | Windows 10

I used git bash to open spyder (by typing spyder in git bash), and lock the screen, then log back in. Spyder disappears, and the stdout in the git bash window says "Segmentation fault".

I do not have any Wacom driver in my system.

Would you be able to relate to any of the known bugs that you know?

[ccordoba12]

Sorry, I have no idea.

[jsh9]

Can you think of any possible reason for the error message "Segmentation fault" showing in the terminal?

Even am struggling with same issue after locking the screen my spyder is getting crashed , how did you find the faulty driver ?

Did a clean installation but still issue persist.

[CAM-Gerlach]

@vipish2804 You could try Spyder 4 bet a7 and see if the issue persists...

Issue got resolved after upgrading Spyder to 3.3.6

[Elly-78]

this is now happening to me. it is driving me crazy I have reinstalled down graded etc and nothing worked. how do I find what is causing this? thanks

[jsh9]

@Elly-78 Have you tried to update your Spyder, your other conda packages, and your operating system to the newest versions possible?

This problem is not due to a bug in Spyder, it is most likely an issue of Windows 10 not working well with Qt. I made this conclusion because at that time, I had another software written in Qt quitting when locking screen as well.

The problem was solved automatically in a while after I updated my Windows 10 (or updated my Qt version, I can't say for sure).

[CAM-Gerlach]

how do I find what is causing this?

@Elly-78 We're going to need to know some more information. Please copy and paste your Spyder version string and all the other versions listed there and provide that here, for starters, as well as a list of _specifically_ step by step everything you've tried thus far. Spyder itself cannot normally cause crashes directly, since its a pure Python application; typically these bugs are due to an issue in Qt, the GUI library Spyder uses.

First, make sure you're using the latest version of everything by running conda install spyder=4.0.1 spyder-kernels=1 pyqt=5.9.2 qt=5.9.7 qtpy qtawesome qtconsole in the Anaconda environment in which Spyder is installed (and if you haven't installed with Anaconda, that is what is recommended to reduce the change of errors like these).

Then, your ensure your OS and drivers are up to date, particularly your GPU drivers, and if you have multiple GPUs (e.g. Nvidia Optimus) try disabling or forcing one or the other. You can also try the settings under Preferences -> General -> Advanced Settings -> Rendering engine and see if they help, as well as disabling any system security software you may have running that can conflict with Spyder.

Other than that, I would refer you to the Spyder troubleshooting guide

[Elly-78]

I am ruining spider 4.0 when I tried to install 4.0.1 I get this:

[CAM-Gerlach]

@Elly-78 Anaconda must not have uploaded it yet to their main channel; it usually takes them a few days. Just be patient on that. Just drop spyder from the list of specs and have it update everything else. Other than that, please provide all the information requested previously as well as the other steps you've taken as recommended above:

Finally, as a sidenote, make sure to include any program output inside triple backticks, like this (quote my post to see the formatting) so it displays properly:

I have uninstalled and reinstalled anacoda I have updated spider and anaconda I have updated windows.

[CAM-Gerlach]

No, I thought I was very clear but I guess not, but that still works, however, as I said before, please put it inside a verbatim block and that inside a details block so it doesn't clog the thread. Just copy/paste the following and then paste everything in the above post inside the inner backticks. You can check that you did it properly by using the "Preview" function.

In any case, I suspect it may be some sort of GPU issue, or some other software on your system (antivirus, security, firewall, etc) that is interfering. Please try the remaining steps above as well as those in the troubleshooting guide. Thanks and best of luck.

first you were clear, this is my first time writing here and i misunderstood. also thanks for your time and patience.

just realized that if Anaconda is in the foreground when I lock the screen then it crashes.
I get a

python has stopped working

[CAM-Gerlach]

You don't see it here? I'm running 4.0.1 (technically via dev build, but it should be the same as the release version) so maybe they changed the name in 4.0.1; UI design and text was one of my areas of expertise but I'm not a Spyder core dev anymore so I don't keep careful track.

just realized that if Anaconda is in the foreground

What do you mean, Anaconda? Anaconda is an entire Python distribution. Do you mean Anaconda prompt, or maybe Anaconda Navigator? On Windows, you shouldn't ever use Navigator and instead always launch Spyder via the shortcut, since its far faster, easier and doesn't involve any number of Navigator-specific bugs.

[Elly-78]

I meant the Navigator, the rendering engine setting was right in front of me but it dose not help.
The problem appears on the window in the foreground if that is the Navigator or Spider. It also happens when I launch spider without the Navigator (as I will do from now on).
Thanks again for taking the time!

The culprit ended up being a faulty Wacom driver service called: _Wacom Tablet Service for ISD_

Disabling that solved the issue. The fun part is that I don't use touch-screen features, nor have a Wacom tablet. Nonetheless, this solved the issue.

Sorry for bothering you for this issue. The first thing I obviously thought of was a problem with spyder, but this ended up being completely innocent.

Thank you for the support
Luca

This worked for me, thanks!
Wacom driver seemed to be at fault. (Device Manager -> Human Interface Devices -> Wacom Device -> either click properties and update under driver or click the "Update device driver" button on the top.

The Wacom driver was not showing as faulty, but manually running a driver update on it seems to have solved the issue.

My system:
Lenovo IdeaPad Flex (Touch screen which I never use)
Spyder 4.0.1
Windows 10
