difficulity installing Hologram SDK, Raspian bullseye or python 3.9.2 problem?

Hardware (and firmware) SDK
#1

Been working for days trying to get Hologram SDK working.
When run: sudo hologram version
in a terminal I get:
sudo: hologram: command not found

When I ran: curl -L hologram.io/python-install | bash to install the SDK part of what I got was:
E: Unable to locate package libpython3.7-dev
E: Couldn’t find any package by glob ‘libpython3.7-dev’

Since the latest version of Raspian is bullseye that comes with python 3.9.2 I’m wondering if one or both of these are the problem.

Any help would be appreciated.

Here are the steps did:

Raspberry pi Model 3B+ V1.3
SARA-R410M modem
fresh install: “Raspbian GNU/Linux 11 (bullseye)”

install Hologram’s SDK
ref: Add Cellular to a Raspberry Pi with Hologram Nova - Hackster.io
sudo apt-get update
run::~ $ python -V returns: Python 3.9.2

~ $ curl -L hologram.io/python-install | bash
returns:

The issue is with an auth package our SDK uses which is only compiled for 3.7

See this PR: Remove dependency on auth package by DomAmato · Pull Request #25 · hologram-io/hologram-python · GitHub

If you want you can checkout that branch and it will work but you wont be able to generate OTPs and will instead have to send the device key to authenticate

Dom,
Thank you VERY much for your rapid response.

For anyone that stumbles onto this thread/problem, here’s the solution I did:
Loaded a legacy version of Raspian. I couldn’t discover how to use the Windows Raspberry Pi Imager to install legacy version of Raspian. So:
from: Operating system images – Raspberry Pi
downloaded a zip file for :
Raspberry Pi OS (Legacy) with desktop
Release date: January 28th 2022
System: 32-bit
Kernel version: 5.10
Debian version: 10 (buster)

Then used Etcher (google it or here’s one “how to” page: ref: https://linuxize.com/post/how-to-install-raspbian-on-raspberry-pi/) to burn Raspian (Buster) onto a SD card.
By default it comes loaded with python2 & python 3:
At a command prompt run: python –V will get:
Python 2.7.16
If run: python3 –V will get:
Python 3.7.3

Then:
Installed hologram
curl -L hologram.io/python-install | bash
no messages; no errors
It Works!
even after running:
sudo apt-get update
sudo apt-get upgrade
python3 stayed at version 3.7.3 (I was scare it might upgrade to 3.9)

#4

I am having the same install issue…I have python 3.9 installed as the latest version, have manually installed 3.7 but can’t figure out how to get the libpython3.7-dev package installed…is there any way to make this work with 3.9? Help.

#5

Marc, I came across the libpython3.7-dev package install problem. Didn’t find a solution. That’s why I started from scratch and loaded a legacy Raspian that had python 3.7 as default. (Don’t know if your using Raspberry pi - if not perhaps there’s a legacy version with python 3.7 of whatever you’re using).

Thanks. Yes, I’m using a Pi and I guess I will do the same thing…very frustrating that the hologram developers are requiring us to use and outdated setup to get this to work.

#7

I posted the branch that should be compatible with python 3.9. installing it is a little less straight forward but you can just use pip like:

pip install -e git+https://github.com/hologram-io/hologram-python.git@refactor/removeauth#egg=hologram-python

The biggest thing is you will have to use device keys since the OTP will no longer work.

Thank you!

I used the pip install method to install the SDK, but when I tried to run it got an error:

sudo ~/.local/bin/hologram send --cloud --devicekey `cat device.key` -t "hello" -v "this is a test"

#10

Hmm I can look into it but the error does seem to be originating from the script you have in .local/bin/hologram. How did you install the script to that location? I ask because even our non-working yet latest SDK is 0.9.1 not 0.9.0: hologram-python/version.txt at develop · hologram-io/hologram-python · GitHub

Though the one in that branch is an older one and still says 0.9.0 so just want to know whats pointing where and how its determining the version numbers. You might have to force install the “older” version if you already have the newer one installed.

This is a process I used to reproduce it…

#12

Thanks, I’ll look more into that. Its obviously been awhile since I made that branch on github to deal with this problem though I do remember it working when I pushed up the branch.

#13

Thanks Dom.

It’s not an emergency, as I’m using RNDIS for this “release”. I do hope to use the sdk someday to be a little more efficient with data.

#14

To just get around the headache for now I released a version for python 3.7, 3.8, and 3.9 and named it as such in the pypi release: python-sdk-auth · PyPI

Try just installing it normally and see if that works for now while I look into this a bit more. Ideally we will decouple the auth package from the SDK so that it doesn’t block people from using it since the SDK itself should work on any version > 3.7 since its not precompiled unlike the Auth library which is not publicly facing.

Awesome, thanks!

Hi Dom,
I followed your instructions but I’m getting the following error:

#17

You can ignore that advice I gave above, I just made new releases instead that target the respective python versions. So just install normally like in our help docs if you are on python 3.9

#18

Hi Dom,
same issue, here is the result; I’m using python 3.9.2

Ah yes that line in the install script, we could def be smarter about that. I’ll change that.

#20

Ok try it now, i changed the lib requirement in the install.sh file
