I am trying to get gnuradio to work in a virtualenv. I want to keep my system somewhat clean and my project needs Python 3.9, but my system Python is 3.8 (Ubuntu 20.04.4 LTS).
I install it using sudo apt install gnuradio, but then it ends up in the system dist-packages and I can't import it in my virtualenv. The imports work fine when running the system Python.
I have tried to recreate my virtualenv to use system packages:
python3.9 -m venv --system-site-packages venv
This at least made my virtualenv able to find gnuradio, but when I try importing stuff it fails in several different ways.
>>> from gnuradio import uhd

I have struggled with this for several days now and found no solution. Is it even possible to run GNU Radio from within a virtualenv?
I have struggled with this for several days now and found no solution.
Your distro's GNU Radio package is built against your distro's python, so you can't use it with a different python.
So, this is expected.
Is it even possible to run GNU Radio from within a virtualenv?
Sure, you'd need to build it from that virtualenv as well, and tell cmake -DCMAKE_INSTALL_PREFIX=/path/to/virtualenv/ to install into it.
We have a pretty nice anaconda packager, so installing GNU Radio into a Python prefix using conda might be the easiest alternative to that.
Alternatively:
Ubuntu 20.04.4 LTS
There's a new Ubuntu LTS version out! If you go for a system upgrade to Ubuntu 22.04 LTS, you get Python 3.10, and a current GNU Radio 3.10.1 "for free".

I've gotten my hands on a AIY voice kit v1 and am stuck with the assistant_grpc_demo.py with it failing at an import statement with the grpc. I should have everything installed already, yet google.auth.transport can't seem to find it. I am using a pi 3 A+. Below is the terminal commands I used and their outputs.
pi#raspberrypi:~ $ cat testinput.py

*Maybe the glibc part is the problem. Not sure how to resolve that as I already have libc6 2.28. Is there a way to get the aiy-python-wheels to work with my set-up or a previous version. Already tried flashing a pre-built official image built on 4-13-2018 with everything set up, though it failed to boot. Trying to download all packages manually. assistant_library_with_button.sh works though.
Not sure how to resolve that as I already have libc6 2.28
The error message says: .../site-packages/grpc/_cython/cygrpc.cpython-37m-arm-linux-gnueabihf.so requires GLIBC_2.33.
Your libc6 is too old for that gRPC package to work -- it was compiled on a newer system.
You must either:
get a different gRPC package -- one compiled on and suitable for running on a GLIBC-2.28 (or earlier) based system, or
get a different GLIBC package (2.33 or later).
So I'm trying to use the IB API wrapper from here and I try running the first line
from ib_insync import *
but am getting the following error:
Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/ib_insync/__init__.py", line 10, in <module>

RuntimeError: IB API from http://interactivebrokers.github.io is required
but I've downloaded the IB API from the IB github (had to use The Unarchiver to unzip) and saved it on my desktop. As far as I can tell there's no pip3 command I can use to install it so I'm not sure what else I can do to install the IB API. I've allowed ticked all the boxes for the API in TWS. I'm not sure why it's not installing properly?
It seems to be the same issue found here but mine is for macosx. I've tried running the commands from README.md and they don't work. It just says no such directory exists.
Installing the a python module as a wheel is optional- its also possible to just include the path to the module in the PYTHONPATH environment variable. But if you're using the commands from the READ.ME to build and install a wheel, make sure you're in the pythonclient folder and then run:
python3 setup.py bdist_wheel
python3 -m pip install --user --upgrade dist/ibapi-9.75.1-py3-none-any.whl
Thats for the current API Latest version as of March 2019 which is 975.1
I'm trying to work on python3 and using mac. I have installed pyobjc-core and pyobjc, but the error said Quartz not found. I'm very new to this kind of installing. Is there any solution?
Here is my error from pycharm:
Traceback (most recent call last):

Process finished with exit code 1
In case anyone stumbles here use:
pip install pyobjc-framework-Quartz
I have solved the problem by
installing pyobjc-framework-Quartz,
it's provided by pycharm
I'd suggest it's best to install all of pyObjC, rather than just specific frameworks. Invariably, if you're working with Quartz, you're going to need various CoreFoundation objects and constants at the very least. To say nothing of AppKit, or other frameworks, depending on what you're doing.
pip install pyobjc (or pip3) should install everything and let you import Quartz. (It works for me on several pythons!)
I'm using Anaconda3 version 4.2.0 on ubuntu (in docker).
Anaconda is installed in /root/anaconda3 folder.
I installed theano_bpr package using pip install theano_bpr.
Now when i open python and try import theano_bpr, i get the following message:
>>> import theano_bpr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/root/anaconda3/lib/python3.5/site-packages/theano_bpr/__init__.py", line 17, in <module>
from bpr import BPR
ImportError: No module named 'bpr'
However, when i navigate to /root/anaconda3/lib/python3.5/site-packages/theano_bpr/ and run python there, i'm able to import theano_bpr.
In /root/anaconda3/lib/python3.5/site-packages/theano_bpr/ there are following files:
__init__.py, bpr.py (this one is causing problems), t.py, and utils.py.
Im trying to use a lib on bsd that was designed for linux for IBM-db connections:
I have installed as per the ibmdocs for linux, and placed the required linux libs in /compat/linux/lib/
But i get the import error:
>>> import ibm_db
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: Shared object "libdb2.so.1" not found, required by "ibm_db.so"
If I place the file manually in /usr/lib or symlink it I get a read error:
>>> import ibm_db
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/lib/libdb2.so.1: Undefined symbol "strcspn"
If anyone could help on this I would be forever grateful!!
I have installed ibm_db and both ibm_db_sa without failure, I just think its more of an issue trying to use the linux app on bsd.
Since it's looking for libraries in /usr/lib, you seem to be running the FreeBSD version of Python.
Since FreeBSD's Linux compatibility is a per process compatibility, you cannot load Linux libraries into a FreeBSD process. If you want to dynamically load Linux libraries, you need to run a Linux version of Python.
