Segmentation Fault #39

Open MayukhSobo opened 6 years ago

MayukhSobo commented 6 years ago

I am getting segmentation fault on the dataset of size (360K, 100). Please help.

Hi,

Please specify OS and pykdtree version.

Is this a problem for a specific dataset or a more general issue dealing with high dimension data? Does the error happen during tree construction or query?

storpipfugl commented 6 years ago

The problem can be reproduced for tree construction on small datasets with high dimension (dims above 75 or so). Probably related to #38

Hello,

The OS is Ubuntu 16.04 LTS with 30 GB or RAM and 12 core intel Xenon CPU. The dinemmtion of the data is (254844, 100), a typical dimension of a word2vec data frame.

Any possible fix for this??
