Fatal Error: "boost/python/numeric.hpp": No such file or directory

Hi,

I was trying to install the Meshy for Dex-Net when I faced the bellow error.
fatal error: boost/python/numeric.hpp: No such file or directory #include "boost/python/numeric.hpp"

• libboost-dev version (1.65.1.0ubuntu1)

How can I fix this? Please let me know.

Regards,
Astha

Have you fixed it?

Verision 1.65 of libboost does not include these files anymore. One could either edit the code to work with version 1.65. (using the boost/numpy.h file). This however requires editting of several variables in the code and was a huge hassle for me.

The easier option is to downgrad the libboost version to 1.58.

The easiest version however entirely, and mostly useful for installing Dex-Net is to use Ubuntu 16.04 instead of 18.04 since with 18.04 and melodic other problems down the line of installation appear which I have yet to fix.

Thought it is years ago, it might be helpful when someone finds at this issue, the simplest solution without the edition of the original codes is to create a symbol link of the numpy.h file.

ln -s path/to/boost/numpy.hpp path/at/the/same/path/numeric.hpp

Creating the symbolic link didn't work me (I'm on Ubuntu 22.04, boost version 1.74.0.3ubuntu7)

[..] the simplest solution without the edition of the original codes is to create a symbol link of the numpy.h file.

ln -s path/to/boost/numpy.hpp path/at/the/same/path/numeric.hpp

What did work for me is making the changes to meshrender.cpp described at BerkeleyAutomation/dex-net#64 (comment).
