ValueError: Kpoint weights should sum up to one while sum_weights is 0.000

[ghost]

I try to plot DOS+BANDS from my GSR file, and i give in pycharm this error:

ValueError: Kpoint weights should sum up to one while sum_weights is 0.000
The list of kpoints does not represent a homogeneous sampling of the BZ
<class 'abipy.core.kpoints.Kpath'>
K-path contains 3 lines. Number of k-points in each line: [11, 13, 17]

To compute a DOS, you need to evaluate an 3d integral in the BZ.
In your case, you ebands object contains k-points along a high-symmetry path.
You can plot a band structure along the k-path by calling ebands.plot() but it's not possible to obtain the DOS from the same ebands object.

To get the DOS, you need a second ebands object with energies in the IBZ.
You can obtain this ebands_kmesh from the GSR.nc file produced by the GS run.
