Why do I get AttributeError: module 'tensorflow' has no attribute 'placeholder'?

Question

I was able to run my python program three weeks ago but now every time I try to run it, I get the following error:

AttributeError: module 'tensorflow' has no attribute 'placeholder'

I have tensorflow installed (version '2.0.0-alpha0'). I have read a couple of posts related to this issue. They say I should uninstall TensorFlow and re-install it again. The problem is that I am running this on a cluster computer and I do not have sudo permissions.

Any idea?

Answer 1

After including the tensorflow compat v1 libraries:

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()`

use the v1 syntax like this:

X = tf.compat.v1.placeholder(dtype="float",shape=[None, n_H0, n_W0, n_C0])
Y = tf.compat.v1.placeholder(dtype="float",shape=[None, n_y]) 

Answer 2

In addition to the @Vishnuvardhan Janapati's answer, you can update folders ("*TREE") and/or files to version 2 of TensorFlow. The upgrade tool tf_upgrade_v2 is automatically included in TensorFlow 1.13 and later.

tf_upgrade_v2 [-h] [--infile INPUT_FILE] [--outfile OUTPUT_FILE]
                   [--intree INPUT_TREE] [--outtree OUTPUT_TREE]
                   [--copyotherfiles COPY_OTHER_FILES] [--inplace]
                   [--reportfile REPORT_FILENAME] [--mode {DEFAULT,SAFETY}]
                   [--print_all]

An illustration of how the conversion fixed the "placeholder" error:

Note: this fixes similar complaints module 'tensorflow' has no attribute 'xxxxx' (not just the "placeholder").
