Trouble with 3d functionality #369
Description
Numpy was not working properly, but after putting
pip uninstall numpy
pip install "numpy<2"
it was resolved. You can add this to README
But i got this error after running
./surface
terminate called after throwing an instance of 'std::runtime_error'
what(): No axis
Aborted (core dumped)
Other examples worked except for:
./nonblock
terminate called after throwing an instance of 'std::runtime_error'
what(): Call to subplot() failed.
Aborted (core dumped)
./lines3d
terminate called after throwing an instance of 'std::runtime_error'
what(): No axis
Aborted (core dumped)
3d functionality does not work and with WITHOUT_NUMPY defined it does not even compile
In function ‘int main()’:
surface.cpp:22:10: error: ‘plot_surface’ is not a member of ‘plt’
22 | plt::plot_surface(x, y, z);

Since this library appears to be have been unmaintained for quite a while there seem to be a lot of inconsistencies related to which python version you should use. I've tried several different python 3 versions and the only one that seems to work is python
3.8.0. Not only that you need to be mindful whichmatplotlib/numpyversion you install. What did the job for me was installingmatplotlibversion3.5.3using the follwing command:Any higher
matplotlibversion breaks the library initialization process. Thenumpylibrary gets automatically installed along withmatplotlibpackage and seems to work correctly. Also, after reinstalling python and those 2 packages you should apply the patch mentioned in #368.
