nvcc not found

[Iamanorange]

Install CUDA Toolkit.

[lovekittynine]

/bin/sh: 1: nvcc: not found I have met this problem,but i have installed cuda-toolkit9.0 and i run nvcc -V shows " Cuda compilation tools, release 9.0, V9.0.176"

[Iamanorange]

Edit Makefile: change GPUCC = nvcc to GPUCC = path/to/nvcc. or Use your current shell to run make.

[lovekittynine]

thanks very much! i have changed nvcc path,and it works.But i have met another problem. 5 errors detected in the compilation of "/tmp/tmpxft_00006e0d_00000000-6_data_augmentation.cu.cpp1.ii".

It's this problem solved? I met a similar problem

@Iamanorange based on the previous post, I change the makefile to F_INC =python -c "import tensorflow; print(tensorflow.sysconfig.get_include())"`

Modify Makefile: TF_LIB = python -c "import tensorflow; print(tensorflow.sysconfig.get_lib())" CGPUFLAGS = -L$(CUDA_HOME)/lib -L$(CUDA_HOME)/lib64 -lcudart -L$(TF_LIB) -ltensorflow_framework

I do the make file again.
