[PYTHON] Cuda installation

Environment Windows 10 Visual Studio 2017 (may not be required) Anaconda 3 (Python 3.7.4)
Installation of various software Be careful about the version of each package As of January 31, 2020, the tensorflow page states: https://www.tensorflow.org/install/gpu

Software requirements The following NVIDIA® software must be installed on your system:

NVIDIA® GPU drivers —CUDA 10.1 requires 418.x or higher.

Installed is ver.441.87 CUDA® Toolkit —TensorFlow supports CUDA 10.1 (TensorFlow >= 2.1.0) 　※https://developer.nvidia.com/cuda-toolkit-archive CUPTI ships with the CUDA Toolkit.
Included in CUDA Toolkit cuDNN SDK (>= 7.6) (Optional) TensorRT 6.0 to improve latency and throughput for inference on some models.
Visual Studio Redistribution v14.0 is required (?), And Visual Studio 2017 was originally included, but just in case, the runtime of Visual Studio 2015, 2017, 2019 is installed. 　https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

Post-installation PATH settings C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\extras\CUPTI\lib64 C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\include C:\SoftTool\cuDNN\cuda\bin

Install Tensorflow

Pip package See the pip install guide for available packages, systems requirements, and instructions. To pip install a TensorFlow package with GPU support, choose a stable or development package:

pip install tensorflow-gpu

Tensorflow says "ver.1.14 and below are separated by CPU and GPU, but 1.15 or later is integrated", but pip install tensorflow alone could not recognize gpu from python. I typed tensorflow-gpu and it was recognized by python. * As mentioned above, the version of Tensorflow is 2.1.
