So I have Python 3 and matplotlib installed globally. If I run python outside of a virtual environment and import matplotlib to check the version it shows 1.5.1 . But I am facing problems installing matplotlib within a virtual environment. I created a virtual environment using the command python3 -m venv ds and activated ds. These are the contents of my requirements.txt
matplotlib==1.4.2
numpy==1.9.1
When I do pip3 install -r requirements.txt I get this
Collecting matplotlib==1.4.2 (from -r requirements.txt (line 1))
Using cached matplotlib-1.4.2.tar.gz
Complete output from command python setup.py egg_info:

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
How should I install matplotlib version 1.4.2 in virtual environment ?
My question has been marked as duplicate but that link doesn't solve my question. The solution given is for Ubuntu
I was able to do it by solving the dependencies for matplotlib,
(if you have brew installed)
then first do brew install freetype followed by brew install ttfautohint --with-qt. After that try again to pip install.
You can use the system package in your virtualenv with this option.
Otherwise, this SO post may help you.

I am able to generate *.dat file:
vikas#server:~/memory_profiler-0.36$ ./mprof run --python test_sl.py
vikas#server:~/memory_profiler-0.36$ ls *.dat
mprofile_20151001035123.dat
But when I am trying to plot graph then it is saying "matplotlib is needed for plotting"
vikas#server:~/memory_profiler-0.36$ ./mprof plot --output=plot.png
matplotlib is needed for plotting.
Did I miss anything?
Function I am profiling is run() which is inside: file_to_be_profiled.py
#!/usr/bin/python
import time

from memory_profiler import profile
from guppy import hpy
#profile
def run():
d = {}
l = []
hp = hpy()
before = hp.heap()
d["k1"] = 'val1'
d["k2"] = 10
count = 0
while (count < 9):
l.append(count)
print 'The count is:', count
count = count + 1
print "Good bye!"
after = hp.heap()
leftover = after - before
print leftover
if __name__ == '__main__':
sys.exit(run())
And I am invoking run() from my test script: test_sl.py:
#!/usr/bin/python
import commands
# for the time being I am running my test to profile method: run() inside file_to_be_profiled.py
run_cmd = './file_to_be_profiled.py

I am running on ubuntu machine. But apt-get install did not worked for me. Then I did the install from source. But then also I am getting same error.

You need to install matplotlib, as instructed (this error in thrown by mprof when it can't find matplotlib).
You can do so using pip pip install matplotlib (you might need to prefix this with sudo) or your package manager:
sudo apt-get install -y python-matplotlib on Debian, Ubuntu and derivatives.
sudo yum install -y python-matplotlib on RHEL, CentOS and derivatives.
It seems matplotlib: 3.0.1 does not go well with python 3.7 in conda environment.
df.plot() command could not be executed properly showing "ImportError: matplotlib is required for plotting" but actually matplotlib is installed.
I tried to downgrade matplotlib to 3.0.0 then everything is fine.
conda install -n [your_conda_envionment] matplotlib==3.0.0
I had same problem on freshely installed Ubuntu 16.04. To solve it, I have installed SciPy like this:
sudo pip install scipy
Also I had to install tkinter lib like this:
sudo apt-get install python-tk
I guess somewhere in the past, matplotlib had scipy as dependency, but now it only has numpy, while mprof plot requires scipy.
I had the same problem. I used memory_profiler lib typing this commands
(mprof run runner.py and mprof plot) and got a message "matplotlib is needed for plotting"
I tried to get rid of this problem following advice I found here but in the result I solved this problem completing these simple steps:
delete files in /usr/lib64/python2.7/site-packages/ connected with matplotlib (or you can uninstall matplotlib using the ordinary way)
use sudo yum-builddep python-matplotlib to install connected packages (222 packages were installed, if you need apt-get, you need this command: sudo apt-get build-dep python-matplotlib)
install matplotlib sudo yum reinstall python-matplotlib (or use install command, with apt-get: sudo apt-get install python-matplotlib)
I believe this will help.

I solved it by taking version 1.5.1
pip install matplotlib==1.5.1
it seems that version 1.5.2 installer is broken.
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Get matplotlib from above location. Choose correct package based on python(2.x/3.x) and bit(32/64) version.
32-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win32.whl
64-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win_amd64.whl
If you face any issues in the middle, please refer to below link:
https://stackoverflow.com/a/38618044/5334188
I had the exact same issue.
Seems that my pip was v7 which is old.
upgraded to v9 with the 'upgrade' button.
then tried to install matplotlib again and was successful this time.
maybe this helps
I came across the same problem with you, and here is my solution
It has the problem with python 3.6 integrated with the newest pip.
so I installed python 3.5.2 with pip, but do not upgrade pip.
And you can get matplotlib installed in this way.
Hope I could provide a possible solution
I solved the same problem in Wİndows 10 as folowing:
1- Download the following files for win32 or win64 python3.7:
matplotlib-2.2.2-cp27-cp37m-win32.whl
or
matplotlib-2.2.2-cp27-cp37m-win_amd64.whl
from the https://www.lfd.uci.edu/~gohlke/pythonlibs/
2- By cmd console run the downloaded file under python:
.\Downloads> python -m pip install matplotlib-2.2.2-cp37-cp37m-win_amd64.whl
you can try the matplolib
I had this problem today with Python 3.8.0 and the installation was successfully with matplotlib==3.2.0rc1 after I installed freetype-py.
Installing the specific matplotlib version 2.2.5 worked for me on Windows 10.
The commmand to install a specific version via pip:
pip install matplotlib==2.2.5
When I try to upgrade my matplotlib using pip, it outputs:

Why did it fail?
Many thanks!
This is a known bug that has been fixed (https://github.com/matplotlib/matplotlib/pull/3414) on master.
The bug is in the handling of searching for a freetype installation. If you install the Linux package freetype-dev, you will avoid this bug and be able to compile matplotlib.
sudo apt-get install libfreetype6-dev
On Ubuntu 14 server, you also need to install libxft-dev
sudo apt-get install libfreetype6-dev libxft-dev
I had the same issues trying to install matplotlib on Python 3 using pip3, and it seems that this problem is related to a bare-bones installation of Python 3, and doing a:
sudo apt-get build-dep matplotlib
followed by
sudo pip3 install matplotlib
is probably a better solution than selectively installing only the libraries related to matplotlib.
Since mac doesn't have apt-get you, on OSX you may need to do:
brew install freetype
then you can run:
pip install matplotlib
Found this page while looking answer for fedora 24.
RPM solution is:
dnf install freetype-devel
If you re running Ubuntu server 14.04 u should add this font dependency
sudo apt-get install libxft-dev
Source
I was trying too update directly using sudo pip but changes are not saved in last. So i first use update cmd in terminal:
sudo apt-get update
then i used sudo install:
sudo apt-get install libffi-dev
Finally its installed by doing this method.
For those on Fedora 25 hitting this thread, I needed these two packages to make it work:
sudo dnf install freetype-devel gcc-c++
This worked for me:
python -m pip install -U pip setuptools
python -m pip install matplotlib
For more details, follow : https://matplotlib.org/2.0.0/users/installing.html
I get ValueError: semaphore or lock released too many times when I try to do pip install matplotlib in Cygwin. What do I do?
UPDATE:
$ pip install matplotlib
Downloading/unpacking matplotlib
You are installing an externally hosted file. Future versions of pip will default to disallowing externally hosted files.
You are installing a potentially insecure and unverifiable file. Future versions of pip will default to disallowing insecure files.

I am not sure if it is the issue with a newest (stable) build of matplotlib, but I ran into the same issue as well.
My solution was to install an older stable version (1.2.1).
Download the 1.2.1 tar file, unzip, and install. Do not use the cygwin compiler option when installing. i.e.
python setup.py build --compiler=cygwin
will fail (did for me), while the usual
python setup.py build
will work. Of course You'll want to follow up with
python setup.py install
Note:
I run a pretty recent cygwin64.
I already had all of the dependencies installed.
I've also tried installing 1.3.0 through pip as well as source. Both threw the same exact error you described here.
Try upgrading the "cygwin" package to version 1.7.26 (http://cygwin.1069669.n5.nabble.com/Problem-with-multiprocessing-module-from-Python-td103816.html).
