solve:AttributeError: module 'tensorflow' has no attribute 'app'

Question

I got an error when I use the code in cmd by using the code:

python generate_tfrecord.py --csv_input=images\train_labels.csv --image_dir=images\train --output_path=train.record""
Usage:
  # From tensorflow/models/
  # Create train data:
  python generate_tfrecord.py --csv_input=data/train_labels.csv  --output_path=train.record

  # Create test data:
  python generate_tfrecord.py --csv_input=data/test_labels.csv  --output_path=test.record

The error message got was:

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

Can any one help me?

Answer 1

If you're using TensorFlow v2, app.run has been moved to tf.compat.v1.app.run, as shown here.

Answer 2

use abseil if you don't want to downgrade

from absl import app

if __name__ == '__main__':

    app.run(main)
