Create a Pourbaix diagram object:

pd = PourbaixDiagram(entries)

>>> Traceback (most recent call last)
~\AppData\Local\Temp\ipykernel_18612\515482332.py in <module>
      1 # Create the Pourbaix diagram object
----> 2 pd = PourbaixDiagram(entries)

D:\Install\anaconda\lib\site-packages\pymatgen\analysis\pourbaix_diagram.py in __init__(self, entries, comp_dict, conc_dict, filter_solids, nproc)
    510             self.pourbaix_elements = self.pbx_elts
    511 
--> 512             solid_entries = [entry for entry in entries if entry.phase_type == "Solid"]
    513             ion_entries = [entry for entry in entries if entry.phase_type == "Ion"]
    514 

D:\Install\anaconda\lib\site-packages\pymatgen\analysis\pourbaix_diagram.py in <listcomp>(.0)
    510             self.pourbaix_elements = self.pbx_elts
    511 
--> 512             solid_entries = [entry for entry in entries if entry.phase_type == "Solid"]
    513             ion_entries = [entry for entry in entries if entry.phase_type == "Ion"]
    514 

AttributeError: 'ComputedStructureEntry' object has no attribute 'phase_type'
