Unable to run pymicro.crystal.texture.Polefigure #1

Closed arunpksh closed 4 years ago

arunpksh commented 4 years ago

Dear pymicro team,

I am trying to understand pymicro and run the examples to plot pole figures. I am executing the examples:

Au_6grains_pole_figure.py Cu_111_pole_figure.py Cu_200_pole_figure.py

Specifically, I am executing the following commands:

from pymicro.crystal.microstructure import Microstructure, Grain, Orientation from pymicro.crystal.texture import PoleFigure from matplotlib import pyplot as plt, colors, cm

eulers = Orientation.read_euler_txt('examples/data/Cu_111.dat') micro = Microstructure(name='Cu_111') for index in eulers: micro.grains.append(Grain(index, eulers[index]))

pf = PoleFigure(hkl='111', proj='stereo', microstructure=micro, verbose=False)

After executing of the last command, I get the following error:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pymicro/crystal/texture.py", line 49, in __init__ self.set_hkl_poles(hkl) File "pymicro/crystal/texture.py", line 80, in set_hkl_poles hkl_planes = self.lattice.get_hkl_family(self.family) File "pymicro/crystal/lattice.py", line 747, in get_hkl_family planes = HklPlane.get_family(hkl, lattice=self, crystal_structure=self._symmetry) File "pymicro/crystal/lattice.py", line 1196, in get_family syms = Lattice.symmetry(crystal_structure) File "pymicro/crystal/lattice.py", line 340, in symmetry return crystal_structure.symmetry_operators() AttributeError: 'str' object has no attribute 'symmetry_operators'

If I now run the command by explicitly specifying the crystal lattice as

pf = PoleFigure(hkl='111', proj='stereo', lattice='cubic',microstructure=micro, verbose=False)

I obtain the following error message:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pymicro/crystal/texture.py", line 49, in __init__ self.set_hkl_poles(hkl) File "pymicro/crystal/texture.py", line 80, in set_hkl_poles hkl_planes = self.lattice.get_hkl_family(self.family) AttributeError: 'str' object has no attribute 'get_hkl_family'

I am not sure how to proceed, since the hkl family has been provided to the command.

Could you please help me.

Rgds, Arun Prakash

Dear Arun,

Thank you for your report, this was due to a bug introduced recently and that has been fixed since then. Could you confirm that this is working now with the latest version ?

Best regards Henry
