Traits error #7

Open Azriro opened 5 years ago

Why do I get this error?

@Azriro Do you still get this error in Python3 ?

Azriro commented 5 years ago

I cannot get mayavi to work with Python3. It said ModuleNotFoundError: No module named 'vtkOpenGLKitPython' when I tried to install mayavi

kuixu commented 5 years ago

@Azriro Maybe you could try to install it from the source at http://www.vtk.org/download/.

Azriro commented 5 years ago

I've already installed mayavi and vtk but the system for some reason couldn't not detect it. I found the vtk folder with vtkOpenGLKitPython but it doesn't seem to read it.

If this might useful:

Traceback (most recent call last): File "", line 1, in File "/home/azri/virtualenvs/venv_devopspy/lib/python3.6/site-packages/vtk/init.py", line 46, in from .vtkOpenGLKit import File "/home/azri/virtualenvs/venv_devopspy/lib/python3.6/site-packages/vtk/vtkOpenGLKit.py", line 9, in from vtkOpenGLKitPython import ModuleNotFoundError: No module named 'vtkOpenGLKitPython'

I've solved the vtkOpenGLKitPython error but now it cannot read the data

kuixu commented 4 years ago

Great! While, where is your data? You can specify your data folder by -d option.

BTW: The default structure of the data folder is https://github.com/kuixu/kitti_object_vis#dataset

Azriro commented 4 years ago

Oh sorry, my bad. Yeah, I did it and it works thanks. Sorry I'm new

Azriro commented 4 years ago

Sorry to bother, last question. I know that the default dataset is 000000, how to change it and can it use a video rather than an image or it can only use an image?

fukatani commented 4 years ago

@Azriro If you want to use specific index, please try $ python kitti_object.py --show_lidar_with_depth --img_fov --const_box --vis --show_image_with_boxes --ind 100

Azriro commented 4 years ago

ohh okay thank you!

hi，can you tell me how to solve the vtkOpenGLKitPython error?

@dfgan This pull(https://github.com/kuixu/kitti_object_vis/pull/25) may help you.
