qt.qpa.plugin problem
Hello i tried to make instalation inside virtualenv with python 3.6.7, Here the steps i made:
pip install mayavi - success
pip install PyQt5 - success
pip install pysurfer - success
jupyter nbextension install --py mayavi --user
jupyter nbextension install --py mayavi --user
Then in Ipython is try next:
In [2]: %gui qt
In [3]: import numpy as np
In [4]: from mayavi import mlab
And the error is:
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
Aborted (core dumped)
How to resolve it?
@vandeppce can you give us some more information about your environment? Are you working on a headless machine? What apt/OS packages did you install/are already installed.
This looks similar to an error we saw in other enthought open source packages on travis CI machines. We were able to fix those issues by installing additional apt packages. See https://github.com/enthought/envisage/blob/23ea9885a75044395942305c1f9edee077a9ffcd/.travis.yml#L9-L15

When I set QT_DEBUG_PLUGINS="1", no lib* packages uninstalled errors raised, it just says that "qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found."
@vandeppce I edited your comment with minor formatting. I hope you don't mind.

Of course not. I have been trapped in this problem for several days, could you please give me some idea on it? Is it a qt problem, or a mayavi problem? By the way, I used it in a Docker container, on a Jupyter Notebook.
Can you tell us what happens if you run the following commands - print(mlab.show_pipeline()) and print(mlab.options).
Also, I'm not sure how you are interacting with the notebook in the container - are you setting up an X server? Are you explicitly using the null backend or using offscreen rendering?

Thanks for your reply. I can not run the above commands, because I can not import mayavi.mlab successfully. I interact with the notebook in the container with a browser, I do not set up an X server, maybe it is the reason? I successfully install mayavi on my Mac osx laptop, but I still wonder the reason for why it failed in the container.
I have the same issue

any help is appreciated
If you import multiple packages in your .py script, you may try import mayavi at the first place. For me, when I change from:
import os
import numpy as np
...
from mayavi import mlab
to
from mayavi import mlab
import os
import numpy as np
...
the issue disappeared.
I solved this problem by “sudo apt-get install libxcb-xinerama0” Hope it works for you
I have had this issue for a week now and nothing helped -- until I ran "sudo apt-get install libxcb-xinerama0"! Thanks a lot @QYWT
from mayavi import mlab crashes the process. Running on Ubuntu Bionic, headless server, conda environment, Python 3.8.8. Below are more details; none of the things proposed in this thread.
I was not expecting the QT display to work anyway on a headless server, but the hard 'abort' crash is brutal and there should be a recoverable state. I know this is probably easier said than done.

I installed PyQt 5.14.2 as a workaround as suggested in tasmota/tasmotizer#71 since I am still on Debian Buster. It works for me now.
If you import multiple packages in your .py script, you may try import mayavi at the first place. For me, when I change from:
import os import numpy as np ... from mayavi import mlabto
from mayavi import mlab import os import numpy as np ...the issue disappeared.
This worked for me.
I have this same issue with importing mlab on headless Debian 5.15 using conda. The suggested fixes here don't work (fails on import of mlab so ordering not the problem and already have libxcb-xinerama0, plus all the others listed here https://github.com/enthought/envisage/blob/23ea9885a75044395942305c1f9edee077a9ffcd/.travis.yml#L9-L15 installed).
Does anyone have any other suggestions?
I fixed this by running Xvfb as per instructions here: https://docs.enthought.com/mayavi/mayavi/tips.html#rendering-using-the-virtual-framebuffer
