The shandite compounds (chemical formula ${M}_{3}{A}_{2}{B}_{2}$) with a kagome structure have recently attracted significant interest due to their novel quantum topological states, such as the ferromagnetic Weyl semimetal in ${\mathrm{Co}}_{3}{\mathrm{Sn}}_{2}{\mathrm{S}}_{2}$, and endless Dirac nodal lines in ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{S}}_{2}$. In this study, we successfully grew ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$ crystal, a sister compound of ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{S}}_{2}$, and investigated its possible topological state and physical properties. Temperature-dependent resistivity measurements of ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$ demonstrate metallic behavior, which can be accurately described by the Bloch-Gr\"uneisen model. This suggests that electron-phonon scattering dominates the electrical transport in ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$, which is also supported by Kohler's rule analysis. The Hall resistivity characterizations reveal the coexistence of both electrons and holes in ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$. Meanwhile, systematic analysis of the de Haas--van Alphen oscillation suggests that there are three Fermi pockets in ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$, and extracted Berry phases are null. Combining first-principles calculation and experimental analysis, we propose that ${\mathrm{Ni}}_{3}{\mathrm{In}}_{2}{\mathrm{Se}}_{2}$ is...
