ValueError: default logger already configured

[GayatriPurandharT]

I am using tensorboard logger with pytorch. I have this error when i write:
configure("runs/run-1234", flush_secs=5)

for step in range(1000):
log_value('v1', epoch, step)
log_value('v2', D_cost.data, step)

what could have gone wrong?

@GayatriPurandharT most likely, configure was already called once, and it's complaining that the logger is already configured. You can either find and remove a second call to configure, or use tensorboard_logger.Logger object and not configure a global logger.
