how to use angr to solve ctf problem while the target elf has PIE?

I try to solve this ctf challenage with angr,but find it has PIE with checksec,I try to solve it with below code,but it does not give me the answer,can you help me?

import angr

main = 0xe04
find = (0x10c8,)
avoid = (0x10bc,)

p = angr.Project('./my_secret')
#state = p.factory.entry_state()
state= p.factory.blank_state(addr=main)
state.posix.files[0].read_from(30)
pg = p.factory.simgr(state, threads=8)
ex = pg.explore(find=find, avoid=avoid)
#ex=pg.explore(find=lambda s:"it is my secret" in s.posix.dumps(1))

output = ex.found[0].posix.dumps(1)
print(output)
inp = ex.found[0].posix.files[0].all_bytes()  
print ex.found[0].solver.eval(inp,cast_to = str)

angr automatically loads PIE binaries at 0x400000. angr has no trouble dealing with PIE binaries.

I think the more pressing issue after “angr cannot just solve this binary outright” is that you’re using addresses copied from IDA - in the case of PIEs, IDA will load the binary at a base address of 0 while angr will load it at a base address of 0x400000. You see a warning about this when loading a PIE in angr.
