Hi, I also have the same problem and would appreciate any help to resolve this issue.

I'm using Windows 10 (64 bit) and Python 3.6.5 |Anaconda, Inc.| [MSC v.1900 64 bit (AMD64)]

@Ecauchy -- please let us know how exactly you did the install? I have no idea which version anaconda ships. Right now if you have numpy installed you should be able to pip install mayavi. On your platform, you should be able to do pip install pyqt5 mayavi and it should work. Uninstall anaconda's version of mayavi and VTK though.

prabhuramachandran on 9 Jun 2018

@prabhuramachandran Just used conda install mayavi. Yes, I do have numpy installed, and I've worked on it for several months perfectly.
The anaconda version of mayavi is mayavi: 4.6.0-py36_vc14_0 conda-forge [vc14].

Ecauchy on 9 Jun 2018

I have the same issue when installing mayavi 4.6.0 (and vtk 8.1.1) from the conda-forge repository. Motivated by the previous comment from @Ecauchy, I checked the version history at conda-forge: It was only recently updated from mayavi 4.5.0 (and vtk 7.1.1).

Installing/Reverting to mayavi 4.5.0 (and vtk 7.1.1) from conda-forge is working.

christian-drescher on 14 Jun 2018

@Ecauchy, @christian-drescher -- can you let me know if removing the conda-forge package and then just doing a pip install of vtk and mayavi works? If so, then this is a conda-forge issue and nothing to do with Mayavi.

prabhuramachandran on 15 Jun 2018

Although it would help to know if it is the VTK package or Mayavi package that has a problem. What if you installed vtk 7.1.1 from conda-forge and pip install mayavi?

prabhuramachandran on 15 Jun 2018

I have the same problem
try this version of vtk, it works on my pc(win10 py3.6)
conda install -c viscid-hub vtk

@prabhuramachandran, this is to acknowledge your request but I have to pass on pip install anything when there is no wheels blob. (I find it troublesome to setup all build tools with restricted rights on my corporate machine.)

christian-drescher on 18 Jun 2018

Having vtk in the __requires__ list in mayavi/__init__.py causes this error. Since only the python wheel version from pypi will provide a distribution for vtk this does not work with any other means of installing vtk (e.g. using conda as many people do). I build a mayavi package myself and have removed the vtk from the __requires__ in order to work with my conda based vtk.

bergtholdt on 21 Jun 2018

@bergtholdt -- Thank you for that. This is unfortunate and another irritating aspect of the different ways we have to package and install things in the Python world. Sigh. So what are we to do now? If I do not have it in the requires then people cannot just run pip install mayavi and expect things to work for the most part. Is this a problem with conda? I am not sure that only a python wheel from pypi has the right to provide a distribution, pip should pick up any installed package typically unless conda is doing something different, no?

prabhuramachandran on 21 Jun 2018

Should we ask the question to the conda developers?

@GaelVaroquaux -- would be great if someone did. Just let me know what the best way to resolve this would be. I will be meeting folks at SciPy this year so can address it then but in the meanwhile it would help if someone could throw some light on this.

prabhuramachandran on 21 Jun 2018

I don't think it has anything to do with the wheel coming from pypi. Just a normal installation via a CMake install mechanism in the standard vtk wrappers does not seem to provide a "distribution" (in the jargon of setuptools / pkg_resources) and so we get this DistributionNotFound error when we import mayavi.mlab. Hopefully the conda-forge maintainers for vtk will be able to provide the package with "distribution support" so that that the __requires__ section in mayavi can be as it is now. So I would suggest to ask the conda-forge maintainers for the vtk recipe to update the recipe using the mechanism from https://github.com/jcfr/VTKPythonPackage, but in a conda compatible way.

bergtholdt on 22 Jun 2018

@prabhuramachandran -- can we talk at sprints this weekend? I'm part of conda-forge and would like to see this get resolved 😀

mwcraig on 13 Jul 2018

(I should add that I'll need help understanding the problem and how VTKPythonPackage solves it).

mwcraig on 13 Jul 2018

@mwcraig -- yes, sure, I plan to be at the sprints tomorrow.

prabhuramachandran on 14 Jul 2018

Should it work now? I have the same problem. I'm using 64-bit Python 3.6.5 with Miniconda.

marcinmatycz on 1 Aug 2018

It ought to IIRC, Matt fixed this at SciPy and the PR has been merged. See the other PR listed above if there are issues. I just tested on Python 3.6 and it does seem to be resolved and fixed. So try installing the conda-forge VTK package and then pip install Mayavi. Closing this as the issue is now resolved.

I have the same problem
try this version of vtk, it works on my pc(win10 py3.6)
conda install -c viscid-hub vtk

i meet the same problem and i solved by using your commands. thanks! But how do you get this commands?

sakimarquis on 26 Sep 2018

Hi, this problem is still on.
I solve it with conda install -c viscid-hub vtk
but for every update, conda updates vtk. So i breaks again.
Can you please fix it?

mariosgeo on 15 Oct 2018

Hi,
I've also this problem. I use conda and conda-forge to install mayavi and vtk, the win64 versions.
I use the viscid-hub workaround but, as said above, it is not very convenient.

Thank you in advance for considering this issue again.

jodemaey on 16 Oct 2018

Can someone who is having this problem please report which version of vtk is installed when you have the problem?

I won't have time to look at this for at least a week or two but if you can recreate the problem and then paste the output of conda list here that would be helpful...

mwcraig on 17 Oct 2018

Here is the output of a test environment to show the problem, and created with

conda install python=3.6.5
conda install -c conda-forge mayavi

Can someone who is having this problem please report which version of vtk is installed when you have the problem?

I won't have time to look at this for at least a week or two but if you can recreate the problem and then paste the output of conda list here that would be helpful...

Now, I find that even import vtk can get this problem:

@ggyyhw -- The first issue is probably because you have ETS_TOOLKIT=null set in your environment. The second looks like a conda VTK build issue. Looks like conda provides its own freetype and vtk requires a newer version. Can you pip install vtk and see if that works for you?

Thanks! As you suggested, I removed conda VTK and conda mayavi (also manually delete all the related folders), then use pip install vtk and pip install mayavi. Now I can successfully import vtk and from mayavi import mlab.

@ggyyhw -- The first issue is probably because you have ETS_TOOLKIT=null set in your environment. The second looks like a conda VTK build issue. Looks like conda provides its own freetype and vtk requires a newer version. Can you pip install vtk and see if that works for you?

Just pip install vtk (without removing conda vtk and conda mayavi) worked for me.

I have the same problem
try this version of vtk, it works on my pc(win10 py3.6)
conda install -c viscid-hub vtk

this helps in win10 conda environment, and this also solved the conflict between opencv and mayavi in my computer. I think linux also suitable.

The solution won't work on win7.

I just experienced this problem installing the latest release version (mayavi-4.6.2 and latest enthought dependencies) via Macports. No Conda, no pip, just setup commands. VTK is 8.1.1 with python extension.

jjstickel on 14 Dec 2018

Same issue, e.g. when using import mayavi.mlab.

DistributionNotFound: The 'vtk' distribution was not found and is required by the application

Anaconda
Windows 10
Python 3.6
VTK 8.1.0
pyQt 5.6.0
mayavi 4.6.2

(packages from from conda-forge)

But import vtk works fine...

Any workarounds for this?

solarjoe on 8 Jan 2019

@solarjoe, as described above, it seems that one workaround is to use pip to install mayavi.

@prabhuramachandran, please reopen. This is is not fixed for reasonable installation cases.

Thanks! As you suggested, I removed conda VTK and conda mayavi (also manually delete all the related folders), then use pip install vtk and pip install mayavi. Now I can successfully import vtk and from mayavi import mlab.

This worked for me too. conda remove vtk conda remove mayavi and installing with pip install vtk and pip install mayavi. Thanks for your help!

Using pip instead of conda for both packages also works for me.

solarjoe on 30 Jan 2019

I would like to point out that this problem also happens on linux (Fedora 30 to be specific).
Installing both vtk and mayavi with the package manager works just fine (dnf install python3-vtk python3-mayavi), but import mayavi.mlab yields the same error message as above.

laolux on 21 Jun 2019

I faced the same problem and waste a lot of time. if you are installing from anaconda command prompt
then the problem can be fixed by following command
conda install mayavi

Remember to run conda activate before launching anything.
