I've just downloaded the getfem pakage for python 3.8.

I work on Windows 10, 64-bit and I installed getfem using the command window:

C:\Users\directory > pip install getfem
Collecting getfem
  Downloading getfem-5.3.5.tar.gz (114 kB)

Requirement already satisfied: scipy in c:\users\umberto cian\appdata\local\programs\python\python38\lib\site-packages (from getfem) (1.4.1)
Requirement already satisfied: numpy>=1.13.3 in c:\users\umberto cian\appdata\local\programs\python\python38\lib\site-packages (from scipy->getfem) (1.18.1)
Installing collected packages: getfem
    Running install for getfem ... done
Successfully installed getfem-5.3.5

Later, I tryed to convert a Harwell-Boeing spars matrix using Spmat function:

import getfem
a = getfem.Spmat('load''harwell-boeing''K.txt')

where is 'K.txt' a Harwell-Boeing format text file (attached).

Running the script I got the following error message:

C:\Users\Umberto Cian\Desktop>py
Traceback (most recent call last):
  File "", line 7, in <module>
    a = getfem.Spmat('load', 'harwell-boeing', 'K.txt')
  File "C:\Users\Umberto Cian\AppData\Local\Programs\Python\Python38\lib\site-packages\getfem\", line 5467, in __init__
  File "C:\Users\Umberto Cian\AppData\Local\Programs\Python\Python38\lib\site-packages\getfem\", line 57, in generic_constructor = getfem_from_constructor(clname,*args)
NameError: name 'getfem_from_constructor' is not defined

It seems to be missing getfem_from_constructor() definition.

Is it possible I made some mistake installing getfem?

Best regards,

Umberto Cian
