如何在Mac或Linux上安装tensorflow 2.0？

Question

TensorFlow 2.0 is released recently. There are no clear steps on how to install it. Any help with the steps for installation is appreciated.

Answer 1

Four other developers have the same problem. The last comment is June 3rd. I eventually sent emails to all the email addresses of the contributors I could find listed at https://github.com/apple/tensorflow_macos , but none of them replied. The repository is now read-only, and archived, allowing no more comments. https://github.com/apple is Apple's official github page.

The world's first trillion-dollar company is unable to support one of its claims about its new computer - that it can be used to do machine learning in Python using Tensorflow. Contrast this with my experience of the open-source programming language Elixir. Every question I have asked at https://elixirforum.com/ got answered within 24 hours by the creator of the language, Jose Valim.

Answer 2

Emmmm, actually is quite easy, though the tensorflow 2.0 is still in experimental stage. It is better to install the preview version in a virtual environment with anaconda, now the following is a Linux example:

$ conda create --name tensorflow_2_0
$ conda activate tensorflow_2_0
$ pip install tf-nightly-2.0-preview # tf-nightly-gpu-2.0-preview for GPU version

Now let's have a try:

$ ipython # or ipython3/python/python3(at least one of which will work)
>>> import tensorflow as tf
>>> print(tf.__version__)
2.0.0-dev20190129

Done.

----------------2019.10.01 Update---------------
Today, the official tensorflow 2.0.0 is published. You can find how to install it here .
Simply, still activate your conda virtual environment and upgrade your pip first with:

pip install --upgrade pip

Then upgrade your tensorflow directly to 2.0.0:

pip install --upgrade tensorflow  # tensorflow-gpu for gpu verison

Finally:

>>> import tensorflow as tf
>>> tf.__version__
'2.0.0'

TENSORFLOW 2.0 release version is out!

Since 01/10/2019 I'm not talking beta but the release version.

Using Anaconda (Recommended)

Since 01/11/2019 Anaconda is supporting the Tensorflow 2.0.0.

Option 1: For what the easiest way is just:

conda install tensorflow or conda install tensorflow-gpu

For the gpu mode, anaconda will take care of all the CUDA everything you need to install for the tensorflow gpu mode to work so I strongly recommend using this method.

Option 2 (virtual env): It is strongly recommended to use an environment on where to install tensorflow, for which you need the following command that will create an environment first and then install tensorflow within:

• CPU: conda create -n <your_env_name> tensorflow
• GPU : conda create -n <your_env_name> tensorflow-gpu

Change <your_env_name> by a meaningful name like tf-2

To use tensorflow run first conda activate <your_env_name>

Using pip

Using pip the tensorflow official instructions are quite complete.

Just install tensorflow using pip like:

# Current stable release for CPU-only
pip install tensorflow

I yet recommend before doing everything to install tensorflow in a new environment so the 3 steps would be (with anaconda):

conda create --n <our_env_name> pip
conda activate <your_env_name>
pip install tensorflow

Now for the GPU version it's harder with pip, I recommend you this link

Answer 4

Thanks for this. I tried following the latest instructions.

Following the instructions at https://github.com/apple/tensorflow_macos In the Terminal on a new Mac M1:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/apple/tensorflow_macos/master/scripts/download__install.sh)"

Confirm y/N? y Installing and upgrading base packages.

Then it says

TensorFlow and TensorFlow Addons with ML Compute for macOS 11.0 successfully installed. To begin, activate the virtual environment:

. "/private/var/folders/6c/56kflzvn7vzcm7vx4kpnw0d00000gn/T/tmp.TNKnwmCZ/tensorflow_macos/tensorflow_macos_venv/bin/activate"

Below /private/var/folders/6c/56kflzvn7vzcm7vx4kpnw0d00000gn/T, the next folder, tmp.TNKnwmCZ, does not exist and /private is owned by root, so executing anything inside it, even if it does exist, requires 'sudo'

Trying the other way of installing Tensorflow given at https://github.com/apple/tensorflow_macos

curl -fLO https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha2/tensorflow_macos-${VERSION}.tar.gz
tar xvzf tensorflow_macos-${VERSION}.tar
cd tensorflow_macos
./install_venv.sh --prompt

It's not clear what VERSION is supposed to be, and https://github.com/apple/tensorflow_macos/releases/download/ does not exist, so the first of the above commands fails, whatever you set VERSION to

Trying another way: git clone https://github.com/apple/tensorflow_macos

cd tensorflow_macos/scripts

./download_and_install.sh 

It tells you to run

. "/private/var/folders/6c/56kflzvn7vzcm7vx4kpnw0d00000gn/T/tmp.xVyjLM93/tensorflow_macos/activate"

and again, these folders only exist down to T, and they are all owned by root

---

So I tried the method recommended above - conda install tensorflow

I found the conda executable in /opt/homebrew/anaconda3/bin

conda install tensorflow

It failed because

• tensorflow -> python[version='2.7. |3.7. |3.6. |3.5. ']

Your python: python=3.8

Apple insists that their tensorflow depends on Python 3.8 https://github.com/apple/tensorflow_macos

Answer 5

In case you are struggling to install Tensorflow on a mac M1 computer, I highly recommend taking a look at this. It works like a charm: https://www.mrdbourke.com/setup-apple-m1-pro-and-m1-max-for-machine-learning-and-data-science/

Answer 6

For anyone still struggling with installing Tensorflow>=2.0 on MacOS, I was able to do the following:

pip install tensorflow-macos

Make sure you have the latest Numpy version though, otherwise you might run into other problems:

pip install numpy --upgrade
