Hello,
I found this email in the README of
https://github.com/efficios/babeltrace/tree/stable-1.5
<https://github.com/efficios/babeltrace/tree/stable-1.5>
I have a question regarding the usage of BabelTrace using version 1.5.8. I am
running on Ubuntu 20.04 and have installed or dependencies to use BabelTrace
with Python bindings:
* sudo apt-get install lttng-tools
* sudo apt-get install lttng-modules-dkms
* sudo apt-get install liblttng-ust-dev
* sudo apt-get install python3-babeltrace
When trying to import BabelTrace in a Python script with “import babeltrace”,
I receive the following error (more error output in the attached text file):
“ModuleNotFoundError: No module named 'babeltrace._babeltrace'” followed by
“ModuleNotFoundError: No module named '_babeltrace'”.
My folder structure at /usr/lib/python3/dist-packages/babeltrace are as follows:
* _babeltrace.cpython-38-x86_64-linux-gnu.so
* Babeltrace.py
* __init__.py
* /__pycache__
I’ve been trying to debug this issue for a couple of days, but am running into
a wall. I’ve decided to email your team in case you have seen this issue
before, or are able to spot a simple issue with my setup.
Thank you,
Jon Smet
Hi Jon,
The Ubuntu python3-babeltrace package contains a binary module
(_babeltrace.cpython-38-x86_64-linux-gnu.so) built for the system's python 3.8
interpreter, in the log file you attached you seem to be using python 3.7
(/usr/lib/python3.7/importlib/__init__.py).
You either need to use the system's python3 interpreter to use the packaged
python3-babeltrace or build your own version of python3-babeltrace against the
python 3.7 interpreter you are using.
Regards,
Michael
