Bu, Tensorflow'un çalışıp çalışmadığını kontrol etmek için bir komut dosyası çalıştırıldığında alınan mesajdır:

SSE4.2 ve AVX'den bahsettiğini fark ettim,
- SSE4.2 ve AVX nedir?
- Bu SSE4.2 ve AVX, Tensorflow görevleri için CPU hesaplamalarını nasıl geliştirir?
- İki kütüphaneyi kullanarak Tensorflow nasıl derlenir?
NOTE on gcc 5 or later: the binary pip packages available on the TensorFlow website are built with gcc 4, which uses the older ABI. To make your build compatible with the older ABI, you need to add --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0" to your bazel build command. ABI compatibility allows custom ops built against the TensorFlow pip package to continue to work against your built package.
buradan unutma tensorflow.org/install/install_sources
bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --config=cuda -k //tensorflow/tools/pip_package:build_pip_package
