Can't install python package with pip



  • Before this summer I was able to install the python package Requests with pip, but not any longer. I wonder if my problem is related to some new update or if I'm doing something wrong.

    Can some of you try to see if you are able to install the Requests package, which I need for handling REST (put/get). These are the commands that I use:

    • opkg install python3
    • opkg install python3-pip
    • pip3 install requests

    The last command ('pip3 install requests') will make the Onion Omega 2 hanging and after a couple of minutes a stack trace is shown.
    I use omega2-v0.1.10-b160.bin, Python 3.6.0.

    Here is the console log



  • it appears that the omega2 is having memory issues. there is a message of 0 swap pages so perhaps setting up a swap file would help?



  • Hi, I used to get a similar error when I tried to install pip & virtualenv for python2, I got it to work by booting from a USB stick (https://docs.onion.io/omega2-docs/boot-from-external-storage.html). I just tried your steps now on my Omega and it worked fine.

  • @Douglas-Kryder and @Gabriel-Gabor. Thanks for your replies.

    Gabriel, your post shows that it is possible, which gives me hope. This week I have followed the link that you posted, but with no success. I have executed the procedure many times, with different Omega2 units. It is strange that I seem to have enough memory left after the crash.

    This is how it looks like after I have get the stack dump after typing 'pip3 install requests':

    ...

  • Today I bought a new USB-memory and made another attempt to install the Requests-package, but with no success. So my problem doesn't seems to be related to any hardware issue (the Omega2 unit nor the USB-memory).

    I will give the Omega2 one more week and if I don't succeed then I will leave it and go for a Raspberry Pi.
