Library is not compatible with Python 3

[chrisb2]

On a new installation of Raspbian I did: 1. Enabled I2C in raspi-config 2. Create a python test file containing just the two imports at the top of your file 3. Ran my test file with python3 -> gave the same import error you get 4. Installed Adafruit_GPIO with: pip3 install AdaFruit_GPIO 5. Ran my test file again -> succeeded with no errors So from this is does look like your system is to blame. So reinstalling Rasbian will work. Chris

To install dependencies for Python 3 on Raspberry Pi, this need to be executed:
sudo python3 -m pip install git+git://github.com/chrisb2/pi_ina219.git
this fixes the import error above.

Thank you so much!! I was really stumped before I found this.

I'm not sure if I am doing something wrong or what but this is not fixing the issue for me? Everything works great if i us Python 2.7, but everything goes to pot when I try it on Python 3.6.
When I run pip list I get:

Adafruit-GPIO (1.0.3)
Adafruit-PureIO (0.2.1)
asn1crypto (0.22.0)
certifi (2017.4.17)

setuptools (36.0.1)
six (1.10.0)
spidev (3.2)
urllib3 (1.21.1)
wheel (0.29.0)

[chrisb2]

If you ran
pip list
then this gives you the packages install for Python 2, to see what is install for Python 3, you need:
pip3 list
Similarly to install the library for Python 3.6 you would need to use pip3. See INSTALLING PYTHON PACKAGES

What error are you getting?
Can you provide an example of the failing code?

regards,
Chris

Similar to rhaejr above, this fix isn't working. I'm getting an error when I run that line:

Looks like I'm having issues cloning the repo. Any thoughts?

[chrisb2]

It looks like from the error:
fatal: unable to connect to github.com
that github.com in not contactable by your machine, what happens if you do:
ping github.com
If this does not work, you may need to check your network setup.

[david-harkey]

I think you're right, it seems to be a network issue. (I can connect to the internet via GUI apps or apt-get commands, but I can't ping or use git to clone)

In any case, I was able to install the package via sudo pip3 install pi-ina219. Thanks for your help!

Hi
I had this problem before and managed to fix it with
sudo python3 -m pip install git+git://github.com/chrisb2/pi_ina219.git
Adafruit_GPIO was indeed not listed on pip3 list.

Unfortunatelly I got some system upgrades and now the following error occurs again:
File "/home/pi/Desktop/python-lis3dh-master/LIS3DH_bus1.py", line 2, in <module> from Adafruit_GPIO import I2C ImportError: No module named 'Adafruit_GPIO'
but now when I checked the lists Adafruit_GPIO was present on both and installing dependecies for python 3 doesn't seem to work :/

Please help

[chrisb2]

Try using pip3 to uninstall pi_ina219 and Adafruit_GPIO, check they are no longer listed by pip3 list, then re-install pi_ina219.

Chris

[GawiQ]

Thanks for response. I tried what you suggested but it didn't work. Still got the same error.

[chrisb2]

Please can you send me a simplied version of the LIS3DH_bus1.py which replicates this issue and I will give it a go myself. This will help to isolate if the issue is in the program or your system. regards, Chris

One more idea, did you try unistalling Adafruit_GPIO and then following manual install instructions here: https://github.com/adafruit/Adafruit_Python_GPIO Chris On Sat, Mar 3, 2018 at 12:13 PM, Chris Borrill <[email protected]> wrote:

LIS3DH_bus1.py.gz
Manual installation didn't work. Do you think system reinstallation would work? Here is the file

[GawiQ]

Did the same and now it works.
Thanks man, really appreciate this. Awesome helping you did here :)
