Error in writing new simulation to file

[xinyuewu21]

In the In[7] cell of the document notebook detector_response, an error appears.

The code is:

E_per_V_1kpc =  E_per_V * ccsn.progenitor_distance.to(u.kpc).value**2
try:
    io.save(conf, E_per_V_1kpc)
except FileExistsError as e:
    print(e)

The error is:
