以下のエラーを解決しないといけない。

I tensorflow/stream_executor/dso_loader.cc:105] Couldn't open CUDA library libcupti.so. LD_LIBRARY_PATH: :/usr/local/cuda/lib64

ls /usr/local/cuda/lib64/で確認したがlibcupti.soというのは見当たらない。

https://devtalk.nvidia.com/default/topic/936212/tensorflow-cannot-find-cudnn-ubuntu-16-04-cuda7-5-/
に以下の記載がある。

sudo apt-get install libcupti-dev zlib1g-dev

上記のapt-getを実行したらエラーが出なくなった。

libcuptiが何かというと以下。
