module 'tensorflow' has no attribute 'placeholder' error

[monistan]

Hi,
I keep getting stuck on this error when I try to run train.py
What is going on and how can I fix this?
ELI5 please because I'm new at this.

File "train.py", line 557, in
main()
File "train.py", line 388, in main
silence_threshold=args.silence_threshold)
File "~/audio_reader.py", line 64, in init
self.sample_placeholder = tf.placeholder(dtype=tf.float32, shape=None)
AttributeError: module 'tensorflow' has no attribute 'placeholder'
