pip throws TypeError: parse() got an unexpected keyword argument 'transport_encoding' when trying to install new packages

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.

    Exception:

Any ideas? (this problem only started after I installed tensorflow) Thanks.

Got the same problem
Does conda install work?
Also, this problem only started after installing TensorFlow.
me too. win 10 and Anaconda 3
I can confirm it happened for me after installing Tensorflow on Anaconda 3 for Windows 10. Installed a bunch of plugins, then after Tensorflow couldn't install any more.

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.


Worked for me too! Thanks
Worked for me too. Thank you. In my case Info was like this: The following packages will be SUPERSEDED by a higher-priority channel: pip: 9.0.1-py36hadba87b_3 --> 9.0.1-py36_0 conda-forge
I had the same problem, like the 6 above, this worked for me as well.
Mine is already on py35h691316f_4 and this command is not changing anything. I'm still getting the exception.
This worked for me: python -m pip install --upgrade tensorflow

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


Piggybacking on Romeo's answer, conda install --force html5lib fixed the problem for me.
tried this for both tensorflow and tensorflow-gpu and doesnt traceback error remains exactly the same: File "C:\Users\Administrator\Anaconda3\lib\site-packages\pip\index.py", line 731, in init namespaceHTMLElements=False, TypeError: parse() got an unexpected keyword argument 'transport_encoding
ok got it working. so its not the tensorflows install that you should replace but your anaconda3 html5lib -> \Anaconda3\Lib\site-packages\html5lib . this made it work for me finally.
@MikeLanzetta solution did not work for me. conda install -c anaconda html5lib worked

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


This does not work for me, Win 10 Anaconda 5.0.0 python 3.6 tensorflow 1.3 cuda 8 and cudnn 6
Looks like you're installing the tensorflow gpu version, not sure that would work with Anaconda.
doesnt work for me either. on keras 2.0.6 py36_0 conda-forge

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.

That worked perfectly for me. (this took a helpful member of our community 8 hours to debug)


what is "activate"? I don't see that as a listed conda command.
it is to use a virtual environment created from [conda] (conda.io/docs/user-guide/tasks/manage-environments.html)
On manjaro linux, the file is located /usr/lib/python2.7/site-packages/pip/_internal/index.py , commented same line. Now works prefectly

pip3 install -U html5lib=="0.9999999"

worked for me

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.
