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

Question

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:
Traceback (most recent call last):

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

Solution 1

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.

Solution 2

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

Solution 3

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

Solution 4

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)

Solution 5

This worked for me:

python -m pip install --upgrade tensorflow
