1. 先安裝miniconda

2.由于后期可能會遇到一個問題，所以可以先安裝 grpcio

conda install grpcio

3. 由于我這邊 tensorflow 下載太慢，所以我還是先用迅雷把安裝包下載了下來

然后執行

pip install tensorflow_gpu-2.0.0-cp37-cp37m-manylinux2010_x86_64.whl

4. 安裝完之后我試著import，沒有看到報錯，暫時先這樣，后面感覺應該是需要安裝cuda的，不知道是不是安裝好了，需要了再補充

如果編譯tensorflow 2.0 gpu版本，默認依賴cuda版本為10.0，我用network版本安裝cuda，默認的驅動版本為libnvidia-common-418，而xubuntu19.10默認的驅動版本為libnvidia-common-435

編譯tensorflow gpu版本時，由于cuda 不支持gcc 8以上的版本，而xubuntu 19.10默認的gcc版本為9.2.1，所以會編譯失敗

編譯TensorFlow CPU版本時，我這邊也失敗了，報錯如下
