      abstract     = {Context. The origin of the astrophysical neutrino flux
                      discovered by IceCube remains largely unknown. Several
                      individual neutrino source candidates were observed. Among
                      them is the gamma-ray flaring blazar TXS 0506+056. A similar
                      coincidence of a high-energy neutrino and a gamma-ray flare
                      was found in blazar PKS 0735+178.Aims. By modeling the
                      spectral energy distributions of PKS 0735+178, we aimed to
                      explore the physical conditions that lead to neutrino
                      production at different stages of the source's
                      activity.Methods. We analyzed the multiwavelength data from
                      the selected time periods. Using numerical simulations of
                      radiation processes in the source, we explored the parameter
                      space of one-zone leptonic and leptohadronic models to find
                      the best-fit solutions that explain the observed photon
                      fluxes.Results. We demonstrated how model parameter
                      degeneracy affected the prediction of neutrino spectra. We
                      showed that the available multiwavelength data were
                      insufficient to predict the neutrino spectrum unambiguously.
                      However, under the condition of neutrino rates maximization,
                      we proposed a scenario in which 0.1 neutrino events were
                      produced during the 50-day flare.Key words: neutrinos /
