Please downgrade to IPython 6 and ipykernel 4.10 to see what happens.

Ares8947 · 2018-10-05T18:18:35Z

I downgrade ipykernel from 5.0.0 to 4.10.0,but Ipython can't downgrade
Not working....

Ares8947 · 2018-10-05T18:22:27Z

but the anaconda 5.2 can work,
update --all,,,
python 3.6.6,
spyder 3.3.1
It can work

but I have obsessive,
I like Latest version......

So....
Sorry...

ccordoba12 · 2018-10-05T19:33:52Z

This is a bad idea. You should update only when necessary or perhaps twice per year. Else, you'll find errors like the one you just reported.

ccordoba12 · 2018-10-05T20:05:22Z

@CAM-Gerlach, are you able to reproduce this?

CAM-Gerlach · 2018-10-05T20:57:25Z

@ccordoba12 Updating to Anaconda 5.3 now to check...

ccordoba12 · 2018-10-05T21:51:04Z

Thanks!

CAM-Gerlach · 2018-10-05T22:07:10Z

@ccordoba12 I wasn't able to update base to anaconda 5.3.0 at the moment since I have several Spyder instances currently open, but I could not reproduce this running the code and hitting the stop button on Windows 8.1 x64 in Spyder 3.3.1 after updating to IPython 7.0.1 and IPyKernel 5.0.0 in a separate Spyder env on Python 3.7.0. a KeyboardInterrupt was raised and execution stopped as expected.

ccordoba12 · 2018-10-05T23:22:38Z

That was my experience on Linux too.

Ares8947 · 2018-10-06T02:19:51Z

@ccordoba12 @CAM-Gerlach
Thanks！

Ares8947 · 2018-10-09T03:03:16Z

@ccordoba12 @CAM-Gerlach Is this bug just happening to me?

CAM-Gerlach · 2018-10-09T04:28:55Z

@Ares8947 Perhaps, but more likely its just another package than the two obvious suspects we tested, ipython and pykernel. It could be something related, like tornado, pyzmq/zeromq, jupyter_client, traitlets, or even a dependency thereof. It could be anything that conda update --all updated, which amounts to dozens and dozens of packages at least, and given the number of combinations of packages and versions is at the very least in the thousands, it may be very difficult to find simply be trial and error without recreating your exact environment. That's why the anaconda metapackage exists and why conda update anaconda or conda install anaconda=X.Y.Z is recommended update method, and/or just updating individual packages like Spyder that don't have many reverse dependencies and that you specifically need.

What I recommend you do is run conda install anaconda=5.3 and see if the issue persists. If it does, then we can properly confirm if we can reproduce it on our end or not. Thanks.

Ares8947 · 2018-10-09T06:00:56Z

@CAM-Gerlach I follow your advice,conda install anaconda=5.3,and reset spyder setting.But the problems still exist.

@CAM-Gerlach Thank you for your time and patience. ：）

Ares8947 · 2018-10-09T06:12:21Z

Anaconda 5.2 python 3.6.6 spyder 3.3.1,The same problem will not arise.
So....I am very sorry to waste your time.
Thanks!

CAM-Gerlach · 2018-10-09T06:13:34Z

@Ares8947 Ares8947 Okay, thanks. I'll boot up my Windows 10 test machine, update an untouched base env to Anaconda 5.3 and see if I can reproduce. For the record, you didn't install any other packages other than those already installed in your base environment, correct? Can you also try creating a new environment (conda create -n spyder-test-env python=3.7), activate it, conda install spyder, and see if it occurs there if you run spyder?

CAM-Gerlach · 2018-10-09T06:16:57Z

Anaconda 5.2 python 3.6.6 spyder 3.3.1,The same problem will not arise. So....I am very sorry to waste your time. Thanks!

You're not wasting our time; you're helping us isolate this issue this it could happen to others. You've already mentioned that this is the case, so I'm not sure how that would invalidate your issue. It may be an hour or so before my machine downloads and installs everything, since I don't regularly update it.

Once you've tried the above, could you try switching python to 3.7 in your current Anaconda 5.2 setup, see if it reoccurs, then upgrade to Anaconda 3 and try Python 3.6 there? Just trying to isolate another variable. If that doesn't change anything, its likely a specific package that's the issue.

Ares8947 · 2018-10-09T06:26:49Z

I am trying.....

Ares8947 · 2018-10-09T17:11:32Z

I think it should be the cause of python3.7 @CAM-Gerlach @ccordoba12

CAM-Gerlach · 2018-10-09T17:13:44Z

I found the v4.0beta2

The current beta is beta 1, so I'm not sure how you found beta 2 since its doens't exist yet :)

I think it should be the cause of python3.7

?

Ares8947 · 2018-11-29T03:21:04Z

@ccordoba12 @CAM-Gerlach
Now I have upgraded to the latest version
anaconda 5.3.1
spyder 3.3.2
The problem remains unresolved
:(

ccordoba12 · 2018-11-29T04:28:18Z

This is not something we can solve in our side, sorry.

Ares8947 · 2018-11-29T05:13:58Z

Oh,god....
I'm used to using spyder.
I like the variable explorer..
I'm sorry to hear that.
@ccordoba12

Ares8947 · 2018-11-29T05:34:12Z

This Bug is a common phenomenon, not just for me.
@ccordoba12

CAM-Gerlach · 2018-11-29T17:09:54Z

@ccordoba12 Okay, then should I report it to ipykernel? I was able to repro it in QtConsole (4.4.1 and 4.4.2 tested): Pressing Ctrl-C or Kernel > Interrupt during time.sleep(10) (eventually) produces a KeyboardInterrupt traceback and stops the command in Python 3.6, while not doing so in Python 3.7. I tested under several different versions of QtConsole, IPykernel, and IPython for both and identical versions of Jupyter_Client and Jupyter_core.

ccordoba12 · 2018-11-29T20:52:35Z

@CAM-Gerlach, yes, if you were able to reproduce this problem in QtConsole, then it's an ipykernel bug. Please ping me and minrk, and reference this issue when reporting.

Does it help to downgrade that package to 4.10?

CAM-Gerlach · 2018-11-30T00:16:45Z

Thanks, I'll report it.

Does it help to downgrade that package to 4.10?

Nope, makes no difference, and neither does 4.8.2 which I tested both previously way back when this was first reported and now. Nor does downgrading IPython to 6.x as well, according to my previous testing.

CAM-Gerlach · 2018-11-30T01:01:59Z

@ccordoba12 Reported there as ipython/ipykernel#374 . Also, I wasn't able to reproduce it on my Fedora 28 Linux VM under various versions on Python 3.7 (and the interrupt was processed vastly quicker than on Windows either way), so it appears to be a Windows-specific bug.

Ares8947 · 2018-11-30T06:47:12Z

Thank you for your help to Windows users.
Thanks!!!!

Nevermind. Found that you perform the following in your Spyder environment
conda install jupyter_client=5.2.4

That's correct; glad you figured it out. Happy Spydering!
