Closed edwinyi closed 5 years ago

edwinyi commented 5 years ago

I follow the steps of "Compile PyFleX with CMake & Pybind11" to install pyflex. After the installation, i have problem to run the example "test_FluidFall.py". The message shows in the terminal is in the following.

Could not initialize GL extensions Segmentation fault (core dumped)

Many thanks if anyone can help me solve the issue.

Can you let me know the version of Ubuntu, Nvidia driver, and CUDA you are using? The repo is tested to work well on Ubuntu 16.04, Nvidia driver 390.87, and CUDA V9.1.85.

Nvidia driver

Hi Yunzhu, I worked on Ubuntu 16.04, Nvidia driver 390.77, and CUDA V9.0.176. I also tried the steps of "Compile and play with the original demo provided by NVIDIA FleX" and I have the same error messages. Thanks!

Would you please install CUDA 9.1 and try again?

YunzhuLi commented 5 years ago

We have reproduced your error using CUDA 9.0. Please try CUDA 9.1 instead.

Thanks, Yunzhu. I will give a try.

It works. Thanks Yunzhu!

We now support compiling PyFleX using docker, and using the functionalities outside docker. Following is a detailed instruction: https://github.com/YunzhuLi/PyFleX/blob/master/bindings/docs/docker.md

I am using Ubuntu16.04, nvidia-440 and cuda-9.1. But I also have such issue, could you please tell me how to solve?

Oh I have solved it. It is because I use sudo ./NVIDIA-Linux-440.run --no-opengl-files when install nvidia driver. It works by reinstalling the driver without the command '--no-opengl-files'.
