i am using a Python module for a LED strip (APA102), that communicates over my Raspberry Pi's SPI pins. When I execute scripts on my WSL2 locally (since I don't have my Pi always with me), i get an exception when trying to import the apa102_pi module with the following traceback:
WARNING: GENERIC_X86 is not fully supported. Some features may not work.

This happens imo because I don't have serial pins available. I already worked with pseudo-terminals before, is it possible to create a workaround with that, or is there another a possibility to create this interface virtually? I actually don't really need the functionality (still would be nice to have that too), but only want to make importing the module work.

I am just getting started on Python, though I know a bit of R. I want to replicate something someone has already done. I am receiving this error on one of my kernels on Jupyter and I don't immediately know what to do about it. Does anyone have any input or experience with it?

And the message :

(Best end a question with the question.) The current working directory for the program does not have a file by that name. Possible solutions:
Give a complete path to the file to read_csv.
Change the working directory in the program to the one that contain that file using os.chdir. See chdir doc.
Start python in that directory, with or without IDLE, from a command line.

It's actually a bug inside Jinja2. Update it to version 2.11.2
You might be blocked by a missing parameter in your config file.
Try to add the following parameter in the file:
server_wide_modules = web
It is a requirement for the installation to go through peacefully.
Hope it helps
Please check your jinja version
maybe wrong with your version jinja
uninstall them
sudo pip3 uninstall Jinja2
then install with right version
sudo pip3 install Jinja2==2.10.1
Matlab engine for python (r2016a) appears to be installed and working with python. I can do the following from a bash prompt:
$ python

Using IPython instead of python gives similar results but with a less informative error. It's clear that Spyder can't find the module matlabengineforpython3_4 but I don't know where to go from there.
How can I get the MATLAB engine to work correctly from within spyder?
This issue might be due to an incompatibility between the libstdc++ shipped with MATLAB and the libstdc++ shipped with the system that the spyder was linked against.
"CXXABI_1.3.9 not found" error message indicates that the libstdc++.so.6 library that is included with MATLAB is missing ABI versions the system needs to draw graphical content.
This is caused because the version of this particular library packaged with MATLAB is older than the versions that come with newer Linux operating systems, which causes compatibility issues.
You can try the following workarounds:
Renaming the libstdc++.so.6 library file so that MATLAB cannot find it and is forced to use the system's version of the library. This file is located in matlabroot/sys/os/glnxa64 . Renaming it to libstdc++.so.6.old should suffice. (where "matlabroot" is root installation directory of MATLAB)
Forcing MATLAB to load the system version by setting the $LD_PRELOAD environment variable to the newer version of libstdc++.
Also, since you are trying to call an external program from MATLAB, this may be a third party issue. But, you can try setting the library paths correctly in 'LD_LIBRARY_PATH' system variable.
find / -name "libstdc++.so*"
I found that calling matlab with the command LD_PRELOAD=/usr/lib64/libstdc++.so.6 matlab -desktop seems to solve the issue
in order to avoid having to type this command every time I also assigned an alias on my .bashrc file alias matlab="LD_PRELOAD=/usr/lib64/libstdc++.so.6 /usr/local/bin/matlab -desktop"

I just installed gsutil on OS X, exactly following Google's instruction, and am seeing errors of the following format when running any gsutil command:
Traceback (most recent call last):

from gslib.command import COMMAND_NAME
ImportError: cannot import name COMMAND_NAME
This error occurs on several modules in the commands directory. The only thing I could do to get rid of these errors is to remove the following modules from the directory which reference COMMAND_NAME: disablelogging, enablelogging, getacl, getcors, getdefacl, getlogging, setacl, setcors, setdefacl.
Did I do the right thing here? Is this a bug in gsutil?
