I am a beginner in python. I am facing the following problem.
Whenever I start pycharm Community edition (version 5.0.3), the Python console fails to starts and shows the following error:

How can I connect to the pycharm console? I have already installed IPython in my system.
I had the same issue.
I solved this by updating ipython.
My version was 3.1.0, upgrading it to 4.1.1 solved it.
in my case:
workon project
pip install -U ipython
I've found that this happened because I had installed ipython version 4.x, and then reverted to 3.2.0, without uninstalling the traitlets more advanced version first. This did the trick then:
pip uninstall ipython[all]
pip uninstall traitlets
pip install ipython==3.2.0
In my case, this was due to a conflicting installation of IPython through pip and apt. Removing the apt-installed version using sudo apt remove ipython fixed the problem.
I initially tried unsuccessfully by trying
pip install -U ipython
But then tried following and it worked:
pip uninstall ipython[all]
pip uninstall traitlets
pip install ipython

I'm running Ubuntu 16.04. I don't know where the application is finding the libpng 1.5.12 version. I could not find it in my system. I installed libpng16-16. It still gives me the same error. I tried out other solutions suggested on the platform but they didn't work
I guess the problem is that you sudo pip installed matplotlib and that the libpng version that is shipped with the manylinux installation package of matplotlib is confused with the libpng version that was installed by apt. I recommend using matplotlib inside a virtual environment.
# create venv
virtualenv ~/matplotlib-venv
# activate venv
source ~/matplotlib-venv/bin/activate
# install matplotlib
pip install matplotlib
pip install <everything else you need>
# run your script
python ~/path/to/your/srcript.py
I am using the latest version of Anaconda3. I just installed it and I am trying to download some packages. I am using the Anaconda Prompt. While trying to use pip to do anything (including upgrading existing packages) I get the following traceback.

Any ideas? (this problem only started after I installed tensorflow) Thanks.
I had the same problem and what worked for me was updating pip with conda:
conda install pip
It changed my pip from 9.0.1-py36hadba87b_3 to 9.0.1-py36h226ae91_4 and solved issue.
download https://github.com/html5lib/html5lib-python/tree/master/html5lib and overwrite all the files within html5lib folder in your tensorflow environment
"envs\tensorflow\Lib\site-packages\html5lib"
Then you should be able to run any "pip install" commands after that
I ran into the same problem while installing keras (after I installed tensorflow 1.3 using pip) on the latest version of Anaconda 3. I was able to fix the problem by installing keras using conda conda install -c conda-forge keras
I was getting this exact error installing SerpentAI. All I did to fix it was run activate serpent in conda prompt and then I ran the command again. Not sure if it's applicable to your situation, but they seem close enough that it might.
EDIT - if the above didn't work, comment out this line:
That worked perfectly for me.
(this took a helpful member of our community 8 hours to debug)
This worked for me:
python -m pip install --upgrade tensorflow
pip3 install -U html5lib=="0.9999999"
worked for me
here's the html5lib bug on github
from: https://stackoverflow.com/a/39087283
Here was the fix for me:
cd /usr/share/python-wheels/
Contents of dir:
-rwxrwxrwx 1 www-data www-data 493905 Jul 22 2015 html5lib-0.999-py2.py3-none-any.whl
-rw-r--r-- 1 root root 112620 Apr 3 2019 html5lib-0.999999999-py2.py3-none-any.whl
Run:
mv html5lib-0.999-py2.py3-none-any.whl html5lib-0.999-py2.py3-none-any.whl.bak
pip3 works fine after. Was loading the old 0.999 version.
Using OSX El Capitan. Just installed a bunch of pip module and was following a few online tutorials, must have broken something as now I get the following error whenever I try to use pip (although python seems to run fine).
$ pip install pandas

Any helping fixing would be much appreciated.
Thanks.
Reinstall using easy_install. Close the terminal and reopen. Pip should now work.
Try updating pip first by typing pip install -U pip and the try pip install pandas. I myself use Anaconda/Miniconda. Most of the packages are well handled and the dependencies are taken care of as well by the conda package manager.
I just recently re-installed Python 2 and Python 3 via homebrew and everything looked ok. However I updated pip3 as well as pip after installing python and then, when trying to install virtualenv, I get the below errors:

pip freeze then seems to think virtualenv is installed but none of it's commands work.
Interestingly if I try to uninstall virtualenv it seems to have it attached to the Python 3 installed by brew installed of the Python 2 version brew installed.

pip freeze gives me:

pbr==1.6.0
virtualenv==13.1.2
virtualenv-clone==0.2.6
wheel==0.24.0
so virtualenv already installed but doesn't work for some reason.
For python 2.7 I believe pip is referenced by pip2. Your permission error is easily fixed by running the command as sudo.
I am going to install numpy library as a *.whl file, as numpy-1.9.2rc1+mkl- cp27-none-win32, on my Windows 7 machine...
Here is my approaches to do that, are which pip and easy_install packages...
The odd thing is that both don't work in the case of either Python 3.4 or Python 2.7...
Here are the trace of the attempts in the command prompt:

Any idea for the problem?!
You should upgrade your pip to version 6.0, the .whl file you're using isn't compatible with earlier versions.
To bump up your pip version on Windows :
python -m pip install -U pip
pip error -> why were you running an install on a pdf? That was never going to work.
easy_install error -> looks like you downloaded a python 2.7 binary and tried to install into a python 3.4 installation.
For scientific stack python, you are hard pressed to beat an Anaconda python distribution.
