我使用此命令安裝了 TensorFlow。
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.7.1-cp27-none-linux_x86_64.whl
這就是它的結果。
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

這時候出現了python2的警告
實際上，我想在 python3 上使用 TensorFlow，我想是因為在 python2 上安裝了 TensorFlow。提示中有很多評論。

它是有效的（？），為什麼有很多警告？
答案1
首先，要將tensorflow與python 3一起使用，您必須使用pip3.如果你還沒有pip3安裝，你可以使用安裝它sudo apt install python3-pip
然後，你可以透過執行以下指令來安裝tensorflow pip3 install tensorflow，不需要使用sudo。
其次，由於 numpy 版本，您會收到警告，您可能擁有安裝的張量流版本不支援的 numpy 版本（1.17 或 1.15）。
因此，要解決這些警告，您可以：
- 安裝tensorflow 2.0，它可以與最新版本的numpy配合良好。命令是
pip3 install --upgrade tensoflow
或者
- 將 numpy 降級到 1.13.3<=numpy<=1.14.5 並保留目前版本的tensorflow。網路攝影機是
pip3 install nupmpy==1.14
注意：您收到的警告並不代表您的安裝失敗。 Tensorflow 工作正常，您可以簡單地忽略它們，一切都會正常工作。
