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)? ________________________________ From: users <users-bounces@lists.sasview.org> on behalf of Ian Billinge via users <users@lists.sasview.org> Sent: 03 June 2024 15:02 To: users@lists.sasview.org <users@lists.sasview.org> 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.
