无法 pip install tensorflow（不再）

Question

Until recently I was able to install the tensorflow 1.5.0 package when using python 3.6.7 on windows. Now I can't and from the message "from version" below it seems that no tensorflow package is available at all.

Did the support stop recently?

Some additional information taking into account the comments from micha137 and hoefling:

In linux, tensorflow is available in many flavors. This is the case with pip version 9.0.3, 10.0.1, and 18.1 I tried.

For example:

(env3)xxx@xxx-linux:/local/mnt/workspace/tmp$ pip install tensorflow==
Collecting tensorflow==
  Could not find a version that satisfies the requirement tensorflow== (from versions: 0.12.0rc0, 0.12.0rc1, 0.12.0, 0.12.1, 1.0.0, 1.0.1, 1.1.0rc0, 1.1.0rc1, 1.1.0rc2, 1.1.0, 1.2.0rc0, 1.2.0rc1, 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.4.1, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9.0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.10.1, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0)

C:\tmp>pip install tensorflow==

Answer 1

Judging by the output of

python -c "from setuptools import pep425tags; print(pep425tags.get_supported()[0])"
('cp36', 'cp36m', 'win32')

you have the supported Python version, but a 32 bit distribution installed (the platform tag is win32 ; for 64 bit Python on Windows, it should be win_amd64 ). Tensorflow is available for 64 bit distributions only ( all the wheels on PyPI have platform tag either macosx_10_11_x86_64 for MacOS, or manylinux1_x86_64 for Linux, or win_amd64 for Windows). Installing the 64 bit Python (eg from python-3.6.8-amd64.exe ) will do the trick.

Answer 2

You could try to list the available versions :

$ pip.exe install tensorflow==
Collecting tensorflow==
   Could not find a version that satisfies the requirement tensorflow== (from ver sions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7. 0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9 .0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0)
No matching distribution found for tensorflow==

Answer 3

try pip3 install tensorflow

if you haven't installed pip3. Do it first.
