ModuleNotFoundError: No module named 'sksparse.cholmod' #1

Closed davidchieregato closed 5 years ago

davidchieregato commented 5 years ago

Hello I can follow all the installation steps apparently succesfully but when I try to use the library in python it is not found: the import from sksparse.cholmod import cholesky returns ModuleNotFoundError: No module named 'sksparse.cholmod' I am using Windows 10 x64 with Anaconda 3 and Visual Studio 2017. I can use the compiled packages in Visual Studio C++ projects so the issue is probably in the python installation script.

Thank you for your reports. That's weird. Please check the following suggestions:

  1. Your installation is using python setup.py install. When you enter from sksparse.cholmod import cholesky, do you use the same python interpreter?

  2. Maybe you can check pip list (with the same python interpreter) to check whether you can see scikit-sparse or not.

davidchieregato commented 5 years ago

pip list will return a long list including scikit-sparse 0.4.3 I have only one python interpreter installed, it's anaconda 3 with python 3.7.3 The situation is actually really strange

xmlyqing00 commented 5 years ago

Yes, that's really strange. It is difficult for me to simulate your environment. Here are some other possible solutions:

  1. Re-run python setup.py install. Maybe it will print something like requirements is already satisfied.
  2. import sys, and print (sys.path). It will print a list of python modules searching path. Your log says the sksparse module is installed in c:\users\david\anaconda3\lib\site-packages\. Check whether this address is in the sys.path.
  3. If not, please add such site-packages path to your system environment. You can search on google for details. Maybe rebooting is required.
  4. Go to c:\users\david\anaconda3\lib\site-packages\ and check there exists a folder named scikit_sparse (or something like this).
  5. Go to python console, type help('modules'), you could see a list of available modules. If everything works well, you are supposed to see sksparse.
  6. Last solution, add the sksparse path temporally to your project by sys.path.append("path/to/module") before import it.

Feel free to ask me any questions.

@ThomasPellegrini Hi, Thank you for your interest. Could you please open a new issue and provide more details about your problem?

xmlyqing00 commented 5 years ago

@stnoh fixed this bug yesterday. You can try the latest codes.

lzcchl commented 2 years ago

@davidchieregato I got this error, but after restart cmd and rerun "from sksparse.cholmod import cholesky", it is ok!

So, no error now? I'm glad this repository still helps many people.
