python-3.x - 解决:AttributeError:模块'tensorflow'没有属性'app'
问题描述
当我通过使用代码在 cmd 中使用代码时出现错误:
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

谁能帮我?
解决方案
如果您使用的是 TensorFlow v2,app.run
则已移至,如此处tf.compat.v1.app.run
