I was using matplotlib and I get an Import error - python-3.x

This is my error traceback:

I tried it after reinstalling matplotlib but nothing works please help.

Ouch! I found out what was happening. I was naming my sample work as one, two, three, etc. and I also had a file "six.py". Make sure you don't have a file named six.py in your path.

In my case it was a privilege problem, I have uninstall cycler and matplotlib by:
sudo pip uninstall cycler matplotlib
and than install them again with:
pip3 install matplotlib
and it works fine, I hope that could help.

Try to install 'cycler' then install 'matplotlib'
pip install cycler
pip install matplotlib

Using Windows 10, anaconda as a package manager. I have a base environment running python 3.7 where matplotlib works fine. When I create a new environment and install both keras and matplotlib, I start to run into problems:

This issue has been reported here and has been fixed here. The fix will be available in matplotlib 3.0.1, which is scheduled to be release within the next few days.
Until then you may either use python <= 3.6.6 with matplotlib 3.0.0. Or you may use matplotlib 2.2.3 or you may try the fix proposed in the linked issue, namely to create a matplotlibrc file in one of the paths where matplotlib would find it.
Try this:
pip uninstall matplotlib
python -m pip install --upgrade pip
pip install matplotlib
Worked perfectly for me
pip uninstall matplotlib
pip install --upgrade matplotlib
works perfectly!
Simply install the appropriate version:
run this in your Jupyter notebook
!pip3 uninstall matplotlib -y
!pip3 install matplotlib==3.0.1
or in terminal:
pip3 uninstall matplotlib -y
pip3 install matplotlib==3.0.1

how am i able to import matplotlib without an error

i have tried several times to import matplotlib and remove reinstall all of the possible combinations
i am using conda as package management system, and pip points to conda
trying to run following programm:
import matplotlib.pyplot as plt
or just:
import matplotlib
creates following result:

i googled a lot and searched left and right, but couldn't get any working solutions (most tell to remove and reinstall numpy/matplotlib which i did several times) please help, if you have any clues
thanks

Error while installing keras in conda using pip

Can anyone help here.
I am trying to install keras in conda using pip and I get below error:
(C:\Users\HARSHALL\Anaconda3) C:\Users\HARSHALL>pip install --upgrade keras

import fiona : ImportError: cannot import name 'calc_gdal_version_num'

I'm trying to install geopandas.
Whether I do one of these :
conda install -c conda-forge geopandas
# or
conda install -c conda-forge fiona
# or
pip3 install Fiona‑1.7.9‑cp36‑cp36m‑win_amd64.whl # downloaded from http://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona
When I try either import geopandas or import fiona, I get the following error :
File "<ipython-input-229-c9ee6bd24dbc>", line 1, in <module>

from fiona.ogrext import (
ImportError: cannot import name 'calc_gdal_version_num'
Any idea on how to solve this ?
(I'm on windows 7 64 bit by the way, in case it's relevant)
EDIT :
It seems this behavior happens only in the IPython console of Spyder (v3.1.4). It doesn't happen when using the python3 command line in the terminal, or the python console of Spyder. I would still love a fix for the IPython console of Spyder, the python console in Spyder is reaaaally slow.

Install PyQt4 via conda for caffe model

I geht the error: ImportError: No module named PyQt4

In this stackoverflow thread they just mention that you can run
conda install pyqt
which results in the following output:
conda install pyqt
Fetching package metadata .......
Solving package specifications: ..........
# All requested packages already installed.
# packages in environment at /home/ec2-user/anaconda2:
#
pyqt 5.6.0 py27_0
Which indicates that I have version 5.6 and not version 4. But I could not find any solution how to downgrade to pyqt4.
so you can Uninstall pyqt5 and download PyQt4 and installed manually
The second option is to modify the code and replace PyQt4 by pyqt5 just pay attention to one thing that the classes in pyqt5 are the same but the irritation is bit different so you may get that specific model doesn't exist in this case check on manual of pyqt5 and fix it
I hope my answer is clear
It looks like the latest version of anaconda forces install of pyqt5.6 over any pyqt build, which will be fatal for your applications. In a terminal, Try:
conda install --channel https://conda.anaconda.org/conda-forge pyqt
conda install -c anaconda pyqt=4.11.4
It will prompt to downgrade conda client. After that, it should be good.
