Path Errors in setup.py

[phipac]

Greetings, all. It seems as though Bosch has changed the directory structure of the bsec file that is downloaded from their site. Here is the output I get when running sudo python3 setup.py on my Raspberry Pi 3B+:

:~/bme68x-python-library $ sudo python3 setup.py install

Looking at the directory structure of the unzipped bsec file, the first issue is the naming of the root directory and the appended date. There is also no longer a 'normal_version' subdirectory. I tried modifying setup.py to reflect the changes, but I keep getting the same error. I appreciate all of your time and efforts!

i had a similar problem and fixed it by creating a folder with the correct name inside the 'bme68x-python-library' folder structure before installing ('bsec2-6-1-0_generic_release' in my case). i used the newest version of bosch's bsec lib (2.6.1.0).

i used this version of @mcalisterkm 's lib: https://github.com/mcalisterkm/bme68x-python-library-bsec2.6.1.0

Thank you for your reply! I tried that. I have the following folder:

/bme68x-python-library-bsec2.6.1.0/BSEC_2.0.6.1_Generic_Release_04302021/algo/normal_version/bin/RaspberryPi/PiThree_ArmV6/

...and the file bsec_interface.h is in that directory. I don't know what I'm still missing here - sorry for my ineptitude.

Started from scratch and tried cloning in the mcalisterkm branch. Still get the following error:

In file included from bme68xmodule.c:4:

[tembhub]

did you use the newest version of bosch's bsec lib? (https://www.bosch-sensortec.com/software-tools/double-opt-in-forms/bsec-software-2-6-1-0-form.html) together with this repository (https://github.com/mcalisterkm/bme68x-python-library-bsec2.6.1.0)?

also you need to create the "bsec2-6-1-0_generic_release" folder inside your "bme68x-python-library-bsec2.6.1.0" repo folder and unpack the bsec library files there. it should look like this:

OK I did not have the bsec directory exactly as that. Looks like the installer worked great this time, but I am unable to call the library. And yes, I did download the latest 2.6.1.0 from Bosch.

$ python gas.py
Traceback (most recent call last):
File "/usr/local/bin/weather-station/gas.py", line 1, in
from bme68x import BME68X
ModuleNotFoundError: No module named 'bme68x'

Thank you for your patience and help!

I am assuming you used this repository (https://github.com/mcalisterkm/bme68x-python-library-bsec2.6.1.0

Did you create and install into a virtual environment?
If so then test it works by running the forced mode example (the README file shows how to do that at line 194, and to invoke and exit at line 70). You may need to edit the address of your sensor.

Providing that works then you can run your gas.py program.
However if you are not in the env then the path for python needs to be changed:

<path/to/venv>/bin/python3  /usr/local/bin/weather-station/gas.py

I am afraid that it all got more confusing with the Debian (Raspbian) decision to distribute core packages by 'apt' and require all other packages to be installed in virtual environments. With the BSEC binary being a separate download we can't do much about this. And … virtual environments are a good thing once you get used to them.

It was the path/to/env/bin/python3. Examples are all working now. Thank you kindoly for your time and patience!
