ubuntu14で750ti geforce gpuを使用してcaffeをコンパイルしようとしていますが、できません。cudnn ライブラリを /usr/local/cuda/lib64 にインストールし、cudnn.h ヘッダー ファイルを /usr/local/cuda/include にインストールしましたが、まだ問題があるようです。Makefile.configでcudNN = 1を有効にすると本当に思います

# cuDNN acceleration switch (uncomment to build with cuDNN).
USE_CUDNN := 1

そこが問題です。これらのエラーは正確には何ですか？

cuDNN R1 をダウンロードしたところ、動作するようになりました。cudNN R2 最新のものは caffe に対応していないようです。

cuDNNv2 で動作する Caffe のバージョンは、S. Layton の github ページから入手できます。

彼の Caffe master ブランチは cuDNNv2 で動作します。github ページからダウンロードできます。

彼は公式の Caffe github にプル リクエストを送信しました。詳細が必要な場合は、ここで完全なディスカッションを入手できます。
