Module not found error when importing umfpack MacOS Monterey M1 chip

I installed umfpack using pip install scikit-umfpack and tried importing the umfpack module
from scikits import umfpack
I'm running into the following error:
Traceback (most recent call last):

ModuleNotFoundError: No module named '__umfpack'

Christian, it's not easy:
pypi umfpack says: first build a local SuiteSparse UMFPACK
building SuiteSparse libraries requires some knowledge of Makefiles
and on macos otool / install_name_tool
before pip install, you need a suitable ~/.numpy-site.cfg.
Added: the setup.py is old and messy;
I had a simpler one which worked onceaponatime, let me know.
You could also try `conda install scikit-umfpack` instead of `pip`,
BUT mixing different package managers is asking for trouble;
if you do, keep the pip and conda package trees separate.

ModuleNotFoundError: No module named 'nvidia.dali.backend_impl' when running nvidia/deeplearningexamples reponstory

run rn50 scripts in NVIDIA/DeepLearningExamples, as
./rn50_partial.sh
get error like this:
Traceback (most recent call last):
File "/export/nfs/sunxue/DeepLearningExamples/PyTorch/Classification/ConvNets/mnasnet/training/FP32/../../../launch.py", line 7, in <module>

ok, I've solved this, cause NVIDIA does not classify the specific installation, actually, it does not have to install from scratch, if you use pip install, just check which version NVIDIA docker use and download this specific version, pip install, and everything will be ok.

Using Python 3 when Python 2.7 is default, pip install error

I originally had both python 2.7 and python 3 installed with python 2.7 as my default in PATH. I needed to run a script using python 3 but could not set it as my default python in PATH for some reason. After just uninstalling python 2.7 I opened 3 and ran the command python get-pip.py install which gave me this error
C:\Python30>python get-pip.py install

I already tried python -m pip install (module name) but it returns No module named pip

I assume you use windows, so here is an answer how to install pip on windows:

On Linux you could just type:
sudo apt install python-pip

Installing GDAL python binding Linux

I've been trying to install the python GDAL binding from source with ./configure --with-python but when i attemp
from osgeo import gdal
I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "osgeo/__init__.py", line 21, in <module>
_gdal = swig_import_helper()
File "osgeo/__init__.py", line 17, in swig_import_helper
_mod = imp.load_module('_gdal', fp, pathname, description)
ImportError: libgdal.so.1: cannot open shared object file: No such file or directory
It seems to me to be an error with swig.

If you have GDAL installed and libgdal.so exists, it looks like the python module is just not finding the library. You can try setting the LD_LIBRARY_PATH environment variable to point to the directory containing libgdal.so (e.g. /usr/local/lib). If that works, run ldconfig to update your library settings so you won't have to set LD_LIBRARY_PATH every time (which many consider a bad idea).

You Can try
sudo apt-get install odbcinst1debian2 libgdal1h
and then try importing

Error when building a project

I cloned an organism project from github.
I tried to install it, but there is no one setup.py file and no documentation.
Could you advise me how to correctly build and install it under Ubuntu 12.04?
I tried so far:
sudo python3 organism.setup.py install
which shows error message:
byte-compiling /usr/local/lib/python3.2/site-packages/organism/coreaux/configuration.py to configuration.pyc
File "/usr/local/lib/python3.2/site-packages/organism/coreaux/configuration.py", line 31
_USER_FOLDER_PERMISSIONS = 0750
^
SyntaxError: invalid token
and running it shows this error message:
$ organism
Traceback (most recent call last):

organism.main()
File "/usr/local/lib/python3.2/site-packages/organism/__init__.py", line 21, in main
import coreaux
ImportError: No module named coreaux
I'm not sure if I should use all the files organism-development.setup.py, organism-organizer.setup.py, organism.setup.py, organism-tk.setup.py in the build process or the error is elsewhere.
