A error will arise when use a slice of a neuron group as post group of a synapse.

A error will arise when use a slice of a neuron group as post group of a synapse.
This error will not arise when jit is set toFalse.

self.E2E = bp.synapses.Exponential(self.E, self.E[:100], bp.conn.FixedProb(0.02),
                                       output=bp.synouts.COBA(E=0.), g_max=we,
                                       tau=5., method=method)
self.E2I = bp.synapses.Exponential(self.E, self.I[:100], bp.conn.FixedProb(0.02),
                                       output=bp.synouts.COBA(E=0.), g_max=we,

Dear @Dong-Jiahuan, this is a very good question. I have figured out what's wrong.
