[Solved] Segmentation Fault (core dump) ** vqa.py**

[oggyfaker]

This issue caused by import lib of decord and pytorch at the same time. For fixing this bug, you should reinstall lib of decord step by step like this:

sudo add-apt-repository ppa:savoury1/ffmpeg4
sudo apt-get update
sudo apt-get install -y build-essential python3-dev python3-setuptools make cmake
sudo apt-get install -y ffmpeg libavcodec-dev libavfilter-dev libavformat-dev libavutil-dev

Make install using cuda

git clone --recursive https://github.com/dmlc/decord
cd decord
mkdir build && cd build
cmake .. -DUSE_CUDA=ON -DCMAKE_BUILD_TYPE=Release
make

Then install for python

cd ../python
python3 setup.py install --user

Finally, you have installed decord correctly. You can re-run the vqa.py.
