For quite some while I've been trying to work with usrp, gnuradio and airprobe. I've successfully received a data dump using usrp but when I try to use gsm_receive100.py on the captured cfile, I am always getting this error:
./gsm_receive100.py cfile
Traceback (most recent call last):
File "./gsm_receive100.py", line 12, in <module>
import gsm
ImportError: No module named gsm
I tried to look every possible place for the particular python module that is missing, both in the web and within the distribution itself but without any success so far. Has anyone faced a similar problem before, and do you know how to solve it?
Supratim -
This is either a problem with your install of the out-of-tree module, or with the module itself. To debug this, you (and anyone helping you) really needs a lot more information:
For starters:
1) What happens when you try to import the module in the Python shell?
2) What turns up when you use slocate to find the module on your computer?
3) What does $ env $PYTHONPATH tell you?
Also, this really isn't a good question for Stack Overflow. This would be better asked on the GNURadio mailing list, which is very active.
For support, you should really look to the mailing lists:
For GNU Radio: https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
For things specific to USRPs: http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
In general, the community uses the lists almost exclusively for support.

I am getting the following error with plotnine==0.9 and matplotlib==3.6.
File "D:\Python\Python310\lib\site-packages\plotnine\stats\stat_density_2d.py", line 3, in <module>
import matplotlib._contour as _contour
ModuleNotFoundError: No module named 'matplotlib._contour'
If I downgrade matplotlib==3.5, the problem goes away.
It's discussed here and it's already fixed here Note that it's already merged to main.
It was due to a internal matplotlib call that is no longer supported and has been replaced.
So I guess you could choose between:
downgrade to mlp 3.5.3
install plotnine#main
till the next plotnine release.
Carlos's answer is correct. However if anybody else, like me, is uncertain of how to install plotnine#main, you can implement the fix rather easily:
Find the site_packages folder you python script uses. It usually is a subdirectory of the python version you are using, which can located reliably by trying to reinstall matplotlib or any other package you know you have access to, and checking the logs in the console. ex using python -m pip install matplotlib.
Go down into the site_packages/plotnine/stats directory and open up the stats_density_2d.py file in your editor of choice.
Apply & save the modifications made in the fix. Alternatively, overwrite the file with the one from the github.
ModuleNotFoundError: No module named 'matplotlib._contour'
Issues with matplotlib 3.6.1 and
plotnine 0.9.0
K.I.S.S.
in terminal:
pip show matplotlib #enables you to check version
pip install matplotlib==3.5 #revert and problem is resolved for now.
no more:
ModuleNotFoundError: No module named 'matplotlib._contour'
resolves issue for now that will stop progress...
I am getting following exception when trying to call feature file of another module from different module with logs as,

Please read this answer for hints on how to handle re-use across Java modules: https://stackoverflow.com/a/58339662/143475
Recommendation is to avoid it as far as possible. And things like call read('../../../../core-utilities/src/main/java/java-functions-calls.feature') lead to un-maintainable tests: https://stackoverflow.com/a/54126724/143475
Most likely the problem is because in the project where you make the call - the utils.Utils class is simply not on the Java "classpath". You should probably take the help of someone who knows Java well, or stick to a simpler "single module" Java project.
I have an Ubuntu LTS20.04 vm with with GNU Radio installed via PPA. Following the Guided Tutorial GNU Radio in C++, I've created, built, and installed a project identical to the sample presented within.
I went to set up the objective flow graph presented at the beginning of the tutorial in GNURadio companion, but when I attempt to execute the it, I get the following error:
Warning: failed to XInitThreads()
Traceback (most recent call last):
File "/home/user/Documents/GNURadio Flowgraphs/testqpsk.py", line 38, in <module>
import tutorial
ModuleNotFoundError: No module named 'tutorial'
What steps do I need to take to resolve this? I should note that the PPA install does not seem to configure paths correctly, as I had to EXPORT GR_PREFIX=/usr to get gr_modtool to function.
The problem was that cmake's default install prefix (/usr/local) does not correspond with default Python search paths. My resolution was the following:
export PYTHONPATH=/usr/local/lib/python3/dist-packages:/usr/lib/python3/dist-packages:$PYTHONPATH
Both this export statement and the GR_PREFIX export were added to my ~/.profile.
I am relatively new to Ansible, and completely new to Alicloud. I am trying to figure out how I can use the list of modules found here: http://47.88.222.42:8080/ansible-alicloud/latest/modules/list_of_cloud_modules.html, or if there is, in fact, a way to do it.
Officially, it seems, Ansible supports only two modules of Alicloud (found here: https://docs.ansible.com/ansible/2.9/modules/list_of_cloud_modules.html), but the other modules I've seen on several websites before as part of tutorials, so I assume they are meant to be working. Can someone help me with this? I was specifically looking at this module: http://47.88.222.42:8080/ansible-alicloud/latest/modules/ali_vpc_module.html#ali-vpc-module
My current issue with it is that when running the playbook with the module, it gives me the error
ERROR! couldn't resolve module/action 'ali_vpc'. This often indicates a misspelling, missing collection, or incorrect module path.
Any help is appreciated.
Thanks in advance!
You need to install the modules by doing pip install ansible-alicloud.
Then you will be able to get the ali_vpc module from /home/cheshi/.local/lib/python3.8/site-packages/ansible/modules/cloud/alicloud/ali_vpc.py
https://pypi.org/project/ansible-alicloud/
Below are the mentioned error while importing pandas library in Power BI in python script.

numpy:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "C:\USERS\YADAVP\ANACONDA3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: DLL load failed: The specified module could not be found.
What is the resolution to sort this kind of error in Power BI?
Forget Anaconda and use WinPython.
I tried Anaconda for days with all the workarounds available in StackOverflow and other forums, and they took me nowhere.
Then I tried WinPython, and it worked immediately. Of course, you will need to change the PowerBI options accordingly.
To install WinPython: https://github.com/winpython/winpython
To change the detected Python home directory: https://learn.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#enable-python-scripting
If you consider my answer, you won't need to downgrade Python, PBI, or anything else.
I had the same error. Unfortunately, PowerBI wont work with Jupyter Notebook Python.
So you have to install a "normal" Python: https://www.python.org/downloads/
And configure the Python you want to use in PowerBI and install your needed Python libraries via pip
Edit: Please use Python 3.8 because 3.9 doesnt support NumPy for now
