pip3 install pandas hangs

Question

I'm trying to install pandas on the raspberry pi 2 (model b, 7 wheezy), python3.5.1, pip 9.0.1 with the command from the title, this is my terminal.

pi@raspberrypi ~ $ sudo pip3 install pandas
Collecting pandas

Requirement already satisfied: python-dateutil>=2 in /usr/local/lib/python3.5/site-packages (from pandas)

Requirement already satisfied: six>=1.5 in /usr/local/lib/python3.5/site-packages (from python-dateutil>=2->pandas)
Installing collected packages: pandas
  Running setup.py install for pandas ... /

I have left it like this for hours, with no progress, what is wrong?

Without success, I have tried:

• Pip Install hangs

• https://bbs.archlinux.org/viewtopic.php?id=174186

Edit in response to Andy K's comment, I have tried the following with apt-get:

pi@raspberrypi ~ $ sudo apt-get install python3-pandas
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package python3-pandas

I've added the correct repositories, but still no joy

Answer 1

I solved this by upgrading the os on the pi, then using the command:

sudo apt-get install python3-pandas

My repositories are now slightly different to in the repositories link in the question, they are below:

deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi

If anyone's interested, the specs are now as below:

PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Finally, with the new os I still could not pip install pandas, i left it running overnight with no success

Answer 2

I've had this same issue on ARM machines using Docker. On my machine python3-pip provided an old pip distribution (9.0.1). So for me upgrading pip & setuptools sufficed

pip3 install -U pip setuptools

Then you can install the rest of your dependencies normally.
