[SasView Users] Cannot find 'sas' module in sasmodels package

[Lucas Wilkins - STFC UKRI via users]

sas is the main package of sasview. I think that line should not be there.

In latest version of sasmodels/data.py it isn't there:


import numpy as np  # type: ignore
from numpy import sqrt, sin, cos, pi

# pylint: disable=unused-import
try:
    from typing import Union, Dict, List, Optional, Tuple, Callable
    Data = Union["Data1D", "Data2D", "SesansData"]

Try cloning the latest sasmodels (and sasdata)?

Subject: [SasView Users] Cannot find 'sas' module in sasmodels package

Hello everyone,

I am trying to run the scripting tutorial<https://www.sasview.org/docs/user/qtgui/Perspectives/Fitting/scripting.html>, and I am unable to run the code because I can't import the 'sas' package.

When I run the import statements at the top of the tutorial, i.e.

import sys
from bumps.names import *
from sasmodels.core import load_model
from sasmodels.bumps_model import Model, Experiment
from sasmodels.data import load_data, set_beam_stop, set_top

I get
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[9], line 4
      2 from bumps.names import *
      3 from sasmodels.core import load_model
----> 4 from sasmodels.bumps_model import Model, Experiment
      5 from sasmodels.data import load_data, set_beam_stop, set_top

File ~/micromamba/envs/smi_py311/lib/python3.11/site-packages/sasmodels/bumps_model.py:20
     16 __all__ = ["Model", "Experiment", "BumpsParameter"]
     18 import numpy as np  # type: ignore
---> 20 from .data import plot_theory
     21 from .direct_model import DataMixin
     23 # pylint: disable=unused-import

File ~/micromamba/envs/smi_py311/lib/python3.11/site-packages/sasmodels/data.py:39
     37 import numpy as np  # type: ignore
     38 from numpy import sqrt, sin, cos, pi
---> 39 import sas
     40 # pylint: disable=unused-import
     41 try:

ModuleNotFoundError: No module named 'sas'

I apparently have sasmodels installed, since I can successfully import load_model from sasmodels.core. However, it seems I am missing the sas package. I have searched online and wasn't able to find any such package. I ran a simple pip install sas, and indeed, something downloaded, but it didn't resolve the issue.

Any insights on the issue would be most appreciated.

Best,

Ian Billinge
