Dataset has not been prepared. Use a random sample. Segmentation fault (core dumped)

when i run python models/votenet.py Show: Dataset has not been prepared. Use a random sample. Segmentation fault (core dumped)

why? thanks!

it' s caused by gcc version required in pointnet2, just update your gcc above 4.9 ,that would be fixed. note: before compiling the pointnet2, clean the stuffs generated during last compiling, or re-unzip the votenet

You can change your gcc and g++ version, I suggest -> gcc 4.9 and g++ 4.9 Then move to the pointnet2 folder and run python setup.py install . Finally, run python demo.py
