conda(ok and Python was updated from 3.7.1 to 3.7.2), then I tried to update
spyderfrom 3.3.2 to 3.3.3 with
conda update spyderand everything broke (I was about to say as usual on Mac) with the following :

Please HELP :-)
delor the debugger. On what lines specifically do they disappear? Can you provide a GIF screenshot showing this behavior?
conda-forgeversions, while presumably the rest of your packages are on AD
defaults. This is not (yet) supported by Anaconda, since the two stacks are not 100% binary compatible and particularly mixing the two when Qt is involved will almost certainly result in errors launching anything requiring it (like Spyder). This was caused by you either using the
-c conda-forgeoption at some point when updating, or adding
conda-forgeto your channel list. Therefore, to resolve this, you should run
conda list, find all the packages listed there that say
conda-forge, and then do
conda install -c defaults NAMES OF PACKAGES HERE. In the future, if you want to install stuff from
conda-forge, you should create a separate isolated environment just for that so as to not contaminate your
I am trying to use spyder to develop some python opencv code, is anyone doing this?
@bafonso A number of people are, yes; there have been many people on here who use it. It seems to be a little tricky to get installed/working, but it seems its perfectly doable.
I need it to be on a docker as I'd like to also use tensorflow...
If you are running your code in a Docker container, you should be able to connect to the kernel within Spyder running on your host OS and use it just like any other IPython Console tab, using the
Connect to kernel dialog and the appropriate version of
spyder-kernels running inside your Docker container.
I have ran into the same issue, it appears one needs to compile qt on ubuntu :/
As I explained in the comment right above yours, the issue is due to mixing
defaults packages, which Anaconda does not support and will specifically lead to Qt problems. The solution is to simply not mix
conda-forge packages in the same environment wherever possible.
How come spyder doesn't have a discourse or similar? seems much more efficient than a chat where things get asked numerous times
The chat is primarily intended for quick questions that aren't answered in our website, README, documentation, troubleshooting guide, wiki, or Stack Overflow (which can all be searched via Google). We have a Google Groups forum for people to ask more substantive questions and search previous replies. The problem with something like discourse is it costs $1200 a year, which is a huge chunk of our limited development budget since we're an entirely community-supported open-source project.
it's a bit of a nightmare, that said, it does work! I should share the Dockerfile and blog post about it.
I'd be happy to take a look at it, if you're able to share at some point. Perhaps we can identify any particular pain points with Spyder that we can fix on our end; we've got big plants for much-improved remote kernel features in Spyder 5 if that gets funded and relates to your problems.
a way to make sure you have appropriate hosting.
Unfortunately we host our site on Github Pages right now, so we'd need to pay for that and its one more outlet to maintain and monitor on top of Github, Gitter, SO, Google Groups, Facebook and Twitter...but we'll certainly keep it in mind and appreciate your suggestion.
more often than not you want to use cv2.imshow()
Does this command not work? Did you try changing the graphics backend?
would the host OS spyder use the host opencv to display the Mat variable in the docker kernel
For plotting, it should use the kernel (inside Docker's) opencv, just like for any other command, while for opening variables in the Variable Explorer it uses the host's. We are going to try to implement arbitrary object support for custom classes without requiring the host environment to have the package it comes from, and in a nicer viewer to boot, but we're not 100% sure if its possible.
