Hello,
I am getting this error while trying to run this part of the code.

def main(unused_argv):
if FLAGS.trace == “”:
raise Exception(“OUT_DIR must be specified”)
print('Constructing models and inputs.')

if FLAGS.mode == "depthflow":  # stage 3: train depth and flow together
    Model = Model_depthflow
    Model_eval = Model_eval_depthflow

    opt.eval_flow = True
    opt.eval_depth = True
    opt.eval_mask = True
elif FLAGS.mode == "depth":  # stage 2: train depth
    Model = Model_depth
    Model_eval = Model_eval_depth

    opt.eval_flow = True
    opt.eval_depth = True
    opt.eval_mask = False
elif FLAGS.mode == "flow":  # stage 1: train flow
    Model = Model_flow
    Model_eval = Model_eval_flow

    opt.eval_flow = True
    opt.eval_depth = False
    opt.eval_mask = False
elif FLAGS.mode == "stereo":
    Model = Model_stereo
    Model_eval = Model_eval_stereo

    opt.eval_flow = False
    opt.eval_depth = True
    opt.eval_mask = False
else:
    raise Exception("mode must be one of flow, depth, depthflow or stereo")


This is the error I am getting:

Can anyone please tell me where I should correct? And, what is this error?
Thanks very much!
