Matplotlib: Nose, Tornado

Question

Because I'm trying to install jupyter on my mac, I upgrated my pip. It showed me everything is all right, but then I noticed this:

    Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-10.0.0b2-py2.7.egg (10.0.0b2)
     matplotlib 1.3.1 requires nose, which is not installed.
     matplotlib 1.3.1 requires tornado, which is not installed.
     matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.

What does this mean? Will my matplotlib work normally even if I don't have numphy>=1.5?

I tried fixing it like suggested matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible but it doesn't work:

sudo -H pip install numphy

Password:
Requirement already satisfied: numphy in /Library/Python/2.7/site-packages (0.0.1)
matplotlib 1.3.1 requires nose, which is not installed.
matplotlib 1.3.1 requires tornado, which is not installed.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.

It's relaxing to see someone has done your job by asking what you exactly needed to. Still, it's a bit cranky to know you are far away from the problems which ppl have faced years ago! — Iqra., Dec 08 '19 at 02:57

I got the same issue. You have to install the said dependencies. Which are nose, tornado, and numpy version greater than 1.5 Do the following

sudo easy_install nose
sudo easy_install tornado

As for the last part regarding numpy version greater than 1.5 you have to get the latest version of python. Refer to here

After some searching I found a way to install the packages without checking the current version, for example, for installing matplotlib:

sudo -H pip install --ignore-installed matplotlib

I am not sure if there is a better way, but at lease it let me keep working. I hope it helps

I was having the nose and the tornado issues on OSX (High Sierra) when I was attempting to install awscli. I got nose and tornado installed with pip itself:

pip install tornado nose --user

Afterwards, the awscli install went smoothly

pip install awscli --user

`--user` will install to the Python user install directory for your platform, e.g., `/Users//Library/Python/2.7/bin`. You might want to add it to the PATH environment variable. – Yuci Mar 30 '19 at 22:04
for me it worked fine after install awscli with ```sudo``` – Thiago C. S Ventura Sep 10 '19 at 13:43

Simply try this command if you have pip installed -

pip3 install pandas --user
