incidentally when you say ‘updated’ Raspbian, what do you mean? … python3-smbus should be installed by default, so it looks like you are using Python 3.5… you haven’t switched the distribution to stretch/sid (unstable) in your apt sources list file, or ran `rpi-update` have you? ---

I have installed Rasbian yesterday from [https://www.raspberrypi.org/downloads/raspbian/](https://www.raspberrypi.org/downloads/raspbian/). Then tried to install the library with the same result. Then sudo apt-get update, sudo apt-get dist-upgrade Nothing else. I am not much in Python, sorry. Current result: ` pi@raspberrypi:~ sudo pip3 uninstall requests Traceback (most recent call last): File "/usr/bin/pip3", line 9, in load_entry_point('pip==1.5.6', 'console_scripts', 'pip3')() File "/usr/lib/python3/dist-packages/pkg_resources.py", line 356, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2476, in load_entry_point return ep.load() File "/usr/lib/python3/dist-packages/pkg_resources.py", line 2190, in load [' __name__']) File "/usr/lib/python3/dist-packages/pip/ __init__.py", line 74, in from pip.vcs import git, mercurial, subversion, bazaar # noqa File "/usr/lib/python3/dist-packages/pip/vcs/mercurial.py", line 9, in from pip.download import path_to_url File "/usr/lib/python3/dist-packages/pip/download.py", line 25, in from requests.compat import IncompleteRead ImportError: cannot import name 'IncompleteRead' pi@raspberrypi:~ sudo apt-get install python3-requests Reading package lists… Done Building dependency tree Reading state information… Done python3-requests is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. pi@raspberrypi:~ $` `` ---

[quote=“radeksulc, post:4, topic:3321”] sudo apt-get dist-upgrade[/quote] this should have no consequence, but I don’t recommend doing a dist-upgrade unless you have to (i.e you know why you need that command as opposed to `apt-get upgrade`) what do you get if you type: ``` `python3 --version` ``` ---

I’ve reviewed the script and I don’t think the issue is your python3 version, but pip3 is broken on your system somehow. It seems I also misremembered the issue and the opposite is true, that is it’s likely your version of the requests module is too new, breaking compatibility with pip 1.5.6 (what ships with Raspbian). I would have to guess that that came about through install of the requests module using pip3 as some point. … you can check the result of my ‘detective work’ in the following topic: [http://forums.pimoroni.com/t/issue-installing-blinkt/3207](http://forums.pimoroni.com/t/issue-installing-blinkt/3207) I would have to stick to my non-commital stance expressed there and probably advise that you start fresh by reimaging Raspbian and don’t permorm a `dist-upgrade` nor run any commands that pip install requests … none of our one-line installers would do that, so running curl -sS [https://get.pimoroni.com/explorerhat](https://get.pimoroni.com/explorerhat) | bash should work. ---

First of all I need to apologize. There was one more step I performed, forgot and did not mention in my previous communication . It was this step “sudo pip install Flask” as part of installation of [https://github.com/sandyjmacdonald/sts\_pi\_controller](https://github.com/sandyjmacdonald/sts_pi_controller) which I started before installation of [https://github.com/pimoroni/explorer-hat](https://github.com/pimoroni/explorer-hat). Now the lib is installed and [test.py](http://test.py) works perfectly. Also the STS-PI controller works. I did not run “sudo pip install Flask” at all. As before - I am not much in Python yet so not able what was the negative effect of this command. Anyway. Thank you for your cool support and immediate responses. Radek
