Tensorflow 集合

Tensorflow 是運用 data flow graphs 觀念進行數值計算的開源程式庫，經常被應用在機器學習和深度神經網路研究等機器智慧研究領域上。

Windows 10 + NVIDIA GPU + TensorFlow

1. 參考 Install TensorFlow with GPU for Windows 10
2. 強烈建議：
• 確實檢查自己的NVIDIA顯示卡是否支援？官網
• Windows設定 %CUDA_HOME% 和添加CUDA相關目錄至%PATH%環境變數
• Anaconda 同時安裝 Python2 和 Python3 兩版本：下載連結
• 建立 Conda tensorflow-gpu 虛擬環境時，記得 Python3版本為 3.5
• conda create -n tensorflow-gpu python=3.5 (暫時別選3.6)
• activate tensorflow-gpu 後，安裝 numbapro 套件
• 開啟 jupyter notebook 後，執行下列 python3 code：參考網站

from numbapro import cuda, vectorize, guvectorize, check_cuda
from numbapro import void, uint8 , uint32, uint64, int32, int64, float32, float64, f8
import numpy as np
check_cuda()

• 確認執行結果是否類似下列結果，最後出現的是 True !：

3. 兩張顯示卡的GPU數量不同，另外在Windows環境設定TF_MIN_GPU_MULTIPROCESSOR_COUNT=2 錯誤訊息才消失

希望大家能少走點冤枉路...:P #
