test_triangle_unstructured_grid():

[bafleck]

I tried to run testscript 'test_triangle_unstructured_grid()' and get the following Error:

Exception has occurred: AttributeError module 'shapefile' has no attribute 'version'

on 15. jul. 2021 I downloaded the program 'triangle' for mac with date: 18.Feb.2021 I copied the program 'triangle' to /usr/bin

I use the following versions: numpy version: 1.18.5 matplotlib version: 3.2.2 flopy version: 3.3.3

Have you installed pyshp? It may be related to the shapefile reader/writer.

I have pyshp installed: Name: pyshp Version: 2.1.3

We can't reproduce this error on our end. The only code that actually evaluates the shapefile version is evaluating shapefile.__version__ not shapefile.version.

Are you running this code from autotest/t075_ugridtests.py?

    maximum_area = 30000.0
    extent = (214270.0, 221720.0, 4366610.0, 4373510.0)
    domainpoly = [
        (extent[0], extent[2]),
        (extent[1], extent[2]),
        (extent[1], extent[3]),
        (extent[0], extent[3]),
    ]
    tri = Triangle(maximum_area=maximum_area, angle=30, model_ws=tpth)
    tri.add_polygon(domainpoly)
    tri.build(verbose=False)
    verts = [[iv, x, y] for iv, (x, y) in enumerate(tri.verts)]
    iverts = tri.iverts
    xc, yc = tri.get_xcyc().T
    ncpl = np.array([len(iverts)])
    g = UnstructuredGrid(
        vertices=verts,
        iverts=iverts,
        ncpl=ncpl,
        xcenters=xc,
        ycenters=yc,
    )
    assert len(g.grid_lines) == 8190
    assert g.nnodes == g.ncpl == 2730

Yes, the error comes at: tri.add_polygon(domainpoly)

def test_triangle_unstructured_grid(): maximum_area = 30000.0 extent = (214270.0, 221720.0, 4366610.0, 4373510.0) domainpoly = [ (extent[0], extent[2]), (extent[1], extent[2]), (extent[1], extent[3]), (extent[0], extent[3]), ] tri = Triangle(maximum_area=maximum_area, angle=30, model_ws=tpth) tri.add_polygon(domainpoly)

Exception has occurred: AttributeError

We can run the same autotest on my machine without any problems. Does this work in a python interpreter?

python
>>> import shapefile
>>> shapefile.__version__

[jdhughes-usgs]

I can reproduce the error if I have a file called shapefile.py with any function in it in the same directory as the script I am running. If you do have such a file you need to rename the script to something else.

[bafleck]

Yes, many thanks this was the reason. Barbara
