Error with running demos: compOmpIsta, lowRankApprox and sparseReco

[ahmadomira]

Trying to run any of the demos directly from default fastmat directory (fastmat/demo) does't work and results following error:

File "~/git/fastmat/fastmat/__init__.py", line 62, in <module>
    from .Matrix import Matrix, Hermitian, Conjugate, Transpose, flags
ModuleNotFoundError: No module named 'fastmat.Matrix'

But copying the demos to an independent directory and running compOmpIsta, lowRankApprox or sparseReco gives:

File "~/fastmat_demo/compOmpIsta.py", line 111, in <module>
    fastmat.algorithms.OMP, mat, b, K)
AttributeError: module 'fastmat' has no attribute 'algorithms'

OS: MacOS Big Sur version 11.0.1 Python: v3.8.6 C-compiler: Clang 6.0 (clang-600.0.57)

How did you install fastmat? …

pip install fastmat

[SebastianSemper]

so you cloned the demos from git and then installed fastmat from pypi and then ran the demos from the git-repository?

The other way around, meaning: pip installed fastmat -> cloned the fastmat repo -> ran the demo directly from the git-repository (-> and later on form a separate directory, as described)

Please check if this is related to #88 and if the suggestions of https://github.com/EMS-TU-Ilmenau/fastmat/issues/88#issuecomment-778697597 might apply here, too

The problem could not be reproduced successfully with the given information. Seems like a problem with importing the package in your local configuration.

Closing the issue for now.
