After Tensorflow-GPU could work If you are not using Nvidia K520 GPU, you need to change "arch=sm_30" to other value in src/net/lib/setup.py and src/lib/make.sh in order to compiler *.so file right. Here is short list for arch values for different architecture.
# Which CUDA capabilities do we want to pre-build for?
# https://developer.nvidia.com/cuda-gpus
# Compute/shader model Cards
# 6.1 P4, P40, Titan X so CUDA_MODEL = 61
# 6.0 P100 so CUDA_MODEL = 60
# 5.2 M40
# 3.7 K80
# 3.5 K40, K20
# 3.0 K10, Grid K520 (AWS G2)
# Other Nvidia shader models should work, but they will require extra startup
# time as the code is pre-optimized for them.
CUDA_MODELS=30 35 37 52 60 61Test your Tensorflow-GPU is running by"
import tensorflow as tf
sess = tf.Session()
print(tf.__version__) # version more than v1. It runs without error message and show ＂successfully opened CUDA library libcublas.so.8.0 locally＂, then it is in CUDA successfully.
source activate didi
sudo chmod 755 ./make.sh
./make.sh
# prerequisite for next step, i.e. running preprocessing using data.py, is to
# follow steps in utils/bag_to_kitti if using didi data
python data.py # for process raw data to input network input format
python train.py # training the network. ./make.sh works.
