Spyder ipython console throws "An error ocurred while starting the kernel" when restarting kernel

Yaozuwu commented 6 years ago

Problem Description

I use anaconda to install python and spyder, and use two environment.But when first open spyder the Ipython console gives an error.

What steps will reproduce the problem?

reset spyder
open it

What is the expected output? What do you see instead?

Paste Traceback/Error Below (if applicable)

I'm a noob, maybe not describe this problem clearly.

CAM-Gerlach commented 6 years ago

Thanks for reporting. Try running the following from the Anaconda prompt or reinstalling Anaconda

conda update spyder ipykernel tornado pyzmq

Also, Please try the steps listed in the Spyder Troubleshooting Guide, specifically the Basic First Aid and Emergency CPR sections, which resolve the great majority of Spyder installation issues.

If it still isn't working, please describe in detail the circumstances in which the error occurred, and post the information listed in relevant subsection of the Calling for Help section as a comment to this issue, and we'll try to help if we can. Otherwise, your issue will likely have to be closed after one week (7 days). Thanks, and best of luck!

Yaozuwu commented 6 years ago

got it, Thank you.

CAM-Gerlach commented 6 years ago

I take it that fixed it?

CAM-Gerlach commented 6 years ago

@sumitroy630 As is clear from the traceback, this issue has nothing to do with this old, closed issue that was evidently due to user error or a machine/install/environment-specific problem. If the items in the troubleshooting guide (mentioned in my comment above) don't help and you go through the steps in the issue checklist without success, then consider posting a new issue. Thanks, and best of luck!

ccordoba12 commented 6 years ago

@sumitroy630, the error you posted above is caused by this file

C:\Users\HP\random.py

Please remove it or rename it to something other than random.py and your problem will be fixed.

glendemasrco commented 6 years ago

Hi,

It amazes me how clueless the people are that both "contribute" to the building of these packages like Anaconda and offer help. Right out of the installation box, after installing Anaconda the spyder console is not working. Then I see about a dozen of "fixes" none of which worked.

I worked in IT for over 20 years and "worse than useless" is how I describe the vast majority of those supposed well meaning people. The would be tossed out the door.

CAM-Gerlach commented 6 years ago

@glendemasrco You seem very frustrated right now, and I'm sorry you're apparently having such a bad time with your Anaconda installation. We all say things in the heat of the moment we later regret, myself as no exception; if you've worked in the user-facing side of the IT world, you've probably experienced at least a few situations of a user getting unreasonably due to a problem you have no direct control over.

In fact, Spyder has no formal relationship (financial or otherwise) with Anaconda, and we have no direct control over your installation, machine, or the third-party dependencies upon which Spyder relies. We are an entirely community-run project; everyone you see providing help and support to users connected to Spyder is a volunteer member of the Spyder community doing it in their free time. As an IT professional yourself, if you've worked a significant amount helping inexperienced users, perhaps you can understand the time we waste and the frustration we sometimes feel answering the same questions and resolving the same problems dozens of times per day from the users who (unlike yourself) choose not to put in the minimal effort to search for their issue, update Spyder and consult our clearly linked troubleshooting resources.

With regard to your problem "the spyder console is not working" is perhaps the most general problem description there is for Spyder (second only to the application itself not launching) and can have a myriad of causes, from an issue with a third-party dependency, to a corrupted installation, to a quirk of your machine, OS or drivers, to simple user error. Naturally, each of these many and varied underlying issues has their own specific solutions, and therefore it should not be surprising that a solution to one user's specific problem won't work if the underlying cause of another's problem is different.

For example, the two issues reported in this thread, despite looking outwardly similar to the untrained eye, were caused by totally different things—one a conflict/bug with third-party-dependencies, and one a user error, both of which we were able to correctly diagnose from the detailed tracebacks those users provided. To compare it to something you're more likely familiar with, it would be like a user complaining that a number of solutions posted in a specific help thread for their internet not working (e.g. reboot router, check cables, disable firewall, etc) didn't work, when their specific problem happened to be e.g. with their modem firmware or due to malware, etc).

So, in order to provide help that is properly useful, you'll need to provide much more information about your problem, something I'm sure you're familiar with coming from IT. Specifically, we need the information requested in the issue template you see above: the full, exact text of your traceback or error message, your OS/Spyder/Python/Qt versions (e.g. from Help > About Spyder), the versions of your key dependencies (Help > Dependencies), and exactly what steps you've already tried. Also, what version of Anaconda you just installed would be helpful as well. Thanks.

Same issue while starting Kernel after updating Spyder to latest version 3.3.1

CAM-Gerlach commented 6 years ago

@omarsalimwaller Yet again, this is not the same issue. Next time, please check at least the last few lines of the traceback to make sure they match the one in the original post; in your case, essentially every single line is different.

This is a duplicate of e.g. #7161 and is likely due to a very old version of one of Spyder's third party dependencies. It should be fixed by running conda update python-dateutil in the Anaconda prompt. If that doesn't do it, reinstalling Anaconda should fix it.

omarsalimwaller commented 6 years ago

Will do, thanks!

@AriseYY Like every other error posted to this thread, this one has nothing to do with the one reported here, as every line of the traceback is completely different. Its not clear what the error message actually is, but at least given everything shown there, there is nothing to indicate any problem with Spyder and rather it seems the error is with TensorFlow and thus it needs to be fixed on their end (or more likely yours). Is that the complete error message.

annaconda 3.6.5

3.6.5 is presumably your Python version, not your "annaconda" [sic] version.

@gaoleicsu, you need to rename your Users directory to something that doesn't have non-ascii characters (i.e. latin letters or numbers with no spaces).

@rishav4336 See #2812 for the solution (conda install jupyter_client=5.3.4 jupyter_core=4.6.0)

Although that doesn't seem to work with the latest conda and Anaconda. If you get an error while doing that, please run instead.

conda update --all
