TensorFlow 安装问题 Mac

Question

I recently started google's machine learning crash course. However it didn't mention how to install TensorFlow, so I went to the website and followed the terminal instructions below for Mac.

$ virtualenv --system-site-packages -p python3 ./venv

$ source ./venv/bin/activate

(venv)$ pip install --upgrade pip

(venv)$ pip list

(venv)$ pip install --upgrade tensorflow

This install step would return,

Requirement already up-to-date: tensorflow in ./venv/lib/python3.7/site-packages (1.12.0) Requirement already satisfied, skipping upgrade: protobuf>=3.6.1 in ./venv/lib/python3.7/site-packages (from tensorflow) (3.6.1)...

The next step was to test tensor flow in python,

(venv)$ python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"

However, this would return,

RuntimeWarning: compiletime version 3.6 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.7 return f(*args, **kwds) 2019-02-05 18:18:09.866187: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA tf.Tensor(-1912.4221, shape=(), dtype=float32)

I've tried to install it outside of the virtual environment but would receive another error.

$ pip3 install --user --upgrade tensorflow

Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow You are using pip version 10.0.1, however version 19.0.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

I've tried a few other variations I found online but still got the same errors. The site I got the instructions on was, https://www.tensorflow.org/install/pip

Tensorflow不适用于Python 3.7 ，请改用Python 3.6 。
