How do I install pandas on Raspberry Pi?

Question

I'm trying to install Python Pandas on my Raspi and I'm finding strange errors.

~ $ pip install pandas
Downloading/unpacking pandas
Downloading pandas-0.13.1.tar.gz (6.1Mb): 6.1Mb downloaded
Running setup.py egg_info for package pandas

and then more (削除) errors (削除ここまで) warnings for a long time. It never actually fails, but doesn't complete either in over half an hour. What is going on here and how do I fix it?

Edited to add

I have tried the alternative route of sudo apt-get install python-pandas which does install pandas but it's only version 0.8 rather than 0.13. Trying to follow up with sudo pip install pandas --upgrade gives the same results as above.

• lenik: what errors?? lines starting with word 'warning' are warnings, ignore them.
• Jamie Bull: It's more the fact that the installation doesn't finish that worried me. This was just the start of a long dump of warnings. Edited to clarify.
• John Ewart: Are you sure it's broken? Pandas relies on numpy which can take an extremely long time to build, even on a very fast desktop machine. Did this ever complete? I'm considering using pandas for a project on my Pi so I'm curious if you had luck with this or gave up.
• Jamie Bull: Yes, it did work. It took a long time to build but got there in the end and has been working fine ever since.
• Ben: Facing the exact same problem myself now, how long did it take in the end @JamieBull ?

Answer 1

Going back to basics, I looked at the installation page for pandas and found that pip install pandas isn't the recommended route on linux systems.

sudo apt-get install python-pandas did the trick.

• wroscoe: This works but installs pandas 0.14.1 (old) when using Raspbian Jessie. Here is an answer that gives two other options. stackoverflow.com/questions/42682928/…
• Rami Alloush: This installs on the default Python 2, for Python 3 use sudo apt-get install python3-pandas
• Ingo: Please accept your own answer with a click on the tick on its left side. Only this will finish the question and it will not pop up again year for year.
• Bamboo: I just tried this on my Pi4B and it seems to have installed v 0.23.3

Answer 2

sudo apt-get install python3-pandas works on the Raspberry Pi4 and the pandas version is 0.23.3.

• SteveC: That is the only way I could install on a Pi3B+

Answer 3

The above answer works but I then faced issues getting pandas into the virtualenv that I had created. Copying this answer

https://stackoverflow.com/questions/29466663/memory-error-while-using-pip-install-matplotlib

from a related matplotlib issue fixed my situation on the latest raspbian install.

Solution: pip --no-cache-dir install pandas

Answer 4

Personally I create a virtual environment and install pandas through pip (the relevant dependencies such as numpy will be installed along the way)

Answer 5

sudo pip3 install pandas worked for mine

• user96931: pip3 is for Python3 whereas the OP was using pip, which means he's using Python 2. Therefore, he should try sudo pip install pandas instead of using pip3, because Python 2 won't be able to find modules installed using pip3.
• Ghanima: @user96931 not necessarily so. This is a pretty old question but on a current system python might (and imho should) link to Python 3 and pip links to pip3.
• user96931: It's better to be explicit than risk error through ambiguity.
