ImportError: bad magic number in 'HologramAuth': b'B\r\r\n' #20

Closed andresvidal closed 4 years ago

Describe the problem

Running the install scripts recommended on the Hologram.io site on a clean Odroid N2 Linux install (arm64) produces and error when loading or running Hologram. I've tried using pipenv for a Python 3.6 and normal pip3 install with no luck.

$ python -V $> Python 3.6.9

Expected behavior

Please describe what you think the program should be doing here.

Actual behavior

(hologram) odroid@mali:~/hologram$ hologram --help Traceback (most recent call last): File "/home/odroid/.local/share/virtualenvs/hologram-2mxoctRU/bin/hologram", line 19, in from scripts.hologram_send import parse_hologram_send_args File "/home/odroid/.local/share/virtualenvs/hologram-2mxoctRU/lib/python3.6/site-packages/scripts/hologram_send.py", line 14, in from Hologram.HologramCloud import HologramCloud File "/home/odroid/.local/share/virtualenvs/hologram-2mxoctRU/lib/python3.6/site-packages/Hologram/HologramCloud.py", line 15, in from HologramAuth import TOTPAuthentication, SIMOTPAuthentication ImportError: bad magic number in 'HologramAuth': b'B\r\r\n'

Steps to reproduce the behavior

Please provide the exact command(s) to reproduce the error. If it's non-deterministic, try your best to describe your observations that might help us troubleshoot the error.

The SDK version 0.9.0 requires python 3.7 or greater. It might install but you will get this bad magic number error on versions of python lower than 3.7

I will close this and reopen if there is a compelling reason to support older versions of python

Thanks. I’ll try it again. Can you guys update the Docs? They are calling for different python versions.

2.7 https://hologram.io/docs/reference/cloud/hologram-cli/

3.7 https://hologram.io/docs/reference/cloud/python-sdk/

Has this really been fixed for ARM with python bytecode??? With hologram v0.9.0 or 0.9.1 I'm having the exact same issue across two ARM platforms: 1) python3.7 on a Raspberry Pi (Buster) and 2) python3.8 on a Jetson Nano (Ubuntu 18.04, Jetpack 4.6.1):

ImportError: bad magic number in 'HologramAuth': b'a\r\r\n'

This is a big problem as we need to deploy a suite of agriculture tools across the USA in ~3 weeks and I'd showcased the Hologram R410M just a few days ago as our proposed solution.

DomAmato commented 2 years ago

We created packages for each of those python versions since it being packaged as bytecode prevented it from being compatible across versions of python: https://pypi.org/project/python-sdk-auth/#history

The versions correspond with the python minor number so 0.3.7 is 3.7, 0.3.8 is 3.8 and so on...

Thank you! I saw this in another post but due to the name being different from the hologram library I didn't understand this was intended to be a second install that fixes the bytecode issue on the hologram-python install. Works on Raspberry Pi, still need to do some digging on the Nano to get it working but I believe my problem is solved.
