不能将pip升级到最新版本9.0.1（操作系统：ubuntu 16.04LTS）

Question

OS: ubuntu 16.04LTS

Python: 2.7.12 + Anaconda2-4.2.0 (64 bit)

I typed pip install --upgrade $TF_BINARY_URL to install tensorflow but terminal showed that my pip verson was 8.1.1 , however version 9.0.1 is available.

Then I typed pip install --upgrade pip to upgrade but it showed Requirement already up-to-date: pip in ./anaconda2/lib/python2.7/site-packages ,

I still can't use pip version 9.0.1 to install tensorflow. Does anyone know what's going on ??

Answer 1

sudo -H pip install --upgrade pip

sudo is "super user do". This will allow you to execute commands as a super user. The H flag tells sudo to keep the home directory of the current user. This way when pip installs things, like pip itself, it uses the appropriate directory.

Answer 2

I had this same problem. Not sure what is going on. I use both python and python3 and have both a pip and a pip3. By chance I did the following and it seems to have fixed the problem.

pip3 install -U pip

resulting in

Collecting pip
  Using cached pip-9.0.1-py2.py3-none-any.whl
Installing collected packages: pip
Found existing installation: pip 8.1.2
Uninstalling pip-8.1.2:
  Successfully uninstalled pip-8.1.2
Successfully installed pip-9.0.1

Answer 3

I have the same problem. But my python is under /usr/bin . I tried sudo -H pip install -U pip , which didn't work. However, when I removed the pip installed by system package manager with

sudo apt-get remove python-pip python3-pip

, the problem was solved. It seems that pip installed with system package manager is not consistent with pip wrapped up with python .

Answer 4

For me none of the above solutions worked, except
easy_install -U pip

UPDATE: easy_install was part of python-setuptools but from version 39.0.1-2 , it is no longer part of it. See changelog .

Answer 5

Try updating pip using conda as follows:

conda update pip

Thereafter try installing tensorflow. See this

Answer 6

I had same problem BUT because of permission . So simple solution for me:

sudo pip install --upgrade pip

Answer 7

如果您只是将东西安装到一个用户帐户，也可以使用pip install --user --upgrade pip避免sudo或不sudo ...请注意不要在系统范围内使用该帐户安装pip好吃的东西。

Answer 8

First, a discussion of the relationship between python and pip. Then how to apply that to your Anaconda - tensorflow problem.

---

"Pip" is a python package, meaning it must be run by a python interpreter. The file(s) you see when calling which pip ( which pip3 ) are actually python scripts, and they are effectively aliasing as follows:

• pip ... results in calling python2.7 -m pip ...

• pip3 ... results in calling python3.5 -m pip ...

Furthermore, in your environment pip is the alias target of pip2 ,

Each version of python has it's own search path, so each version finds a different version of the pip package. Moreover,

when the python2.7/sitepackages/pip is called by python2.7 , it will install in /home/<user>/.local/lib/python2.7/site-packages (or the window equivalent)

and when the python3.5/site-packages/pip is called by python3.5 , it will install in /home/<user>/.local/lib/python3.5/site-packages (or the window equivalent)

It is impossible for python2.7 to call python3.5/.../pip , and impossible for python3.5 to call python2.7/.../pip - so fortunately we don't even have to consider those combinations, whew!

Why did your system not want to upgrade the pip in python2.7/.../site-packages ? My guess is that was by design. By the way, are you sure tensorflow is written in python2.7 and not python3.5 ?

---

To get back to your question: I found this link which may be of interest to you:

Installing Tensorflow on windows Anaconda2

It appears that the OP was trying to use tensorflow which required python3.5, into Anaconda2 which uses python2.7.

Perhaps you could upgrade to Anaconda3 which uses python3.5? (There might be other ways, but upgrading Anaconda seems klike the one with the least liklihood of cross version problems).

Then you install your tensorflow module with

python3 -m pip install tensorflow

Answer 9

cannot install pip 9 for python3 on ubuntu16 with pip or pip3

solve by: sudo apt-get upgrade python3-pip (here may be run the apt update first.)
pip3 -V pip 9.0.1 from /home/roofe/.local/lib/python3.5/site-packages (python 3.5)

Answer 10

Unsurprisingly none of the answers here worked for me either. What did work was to go to https://pypi.org/project/pip/9.0.3/#files and download the wheel file. Then I ran pip install --user pip-9.0.3-py2.py3-none-any.whl . That successfully got me to 9.0.3 .

After that I did pip install --user --upgrade and it successfully upgraded me to 10.0.0 . I suppose I could have directly installed 10.0.0 but I also wanted to double check that there wasn't anything else wrong in the chain.

Anyway, here is where you can download the latest pip: https://pypi.org/project/pip/#files

Answer 11

This is not an actual solution, but the output of the commands above, and who knows, maybe useful for some

To sum up what's going on here. The system is a Raspbian 8 Jessie LITE running on a Raspberry Pi 3 meta B, so in short, it's a Debian based Linux OS just like Ubuntu.

On this system the command pip install --upgrade pip doesn't do the job. My thinking is it just simply can't do it because of the required Debian packages which are installed with the sudo apt-get upgrade python-pip command (about 27MB). Pip just simply not allowed to upgrade Debian packages.

I think the source of difference in results for the self-updating command is a minor version difference which doesn't need system level upgrade can be done like that but every other case will require an actual software upgrade, but I may be wrong. Based on my little investigation the correct solution for Debian Linux is:
sudo apt-get upgrade python-pip
or
sudo apt-get upgrade python3-pip
as others stated before.

Answer 12

I removed the pip installed by system package manager

sudo apt-get remove python-pip

than I needed to dwonload it from the dist page

cd ~/Downloads
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

that solved the problem
