|
| ## Loading the Dataset |
|
|
| ```python |
| import tensorflow as tf |
| |
| # Load TFRecords |
| dataset = tf.data.TFRecordDataset([ |
| 'fastumi_test/1.0.0/fastumi_test-train.tfrecord-00000-of-00001' |
| ]) |
| |
| # Parse function |
| def parse_episode(serialized): |
| features = { |
| 'episode_id': tf.io.FixedLenFeature([], tf.string), |
| 'num_steps': tf.io.FixedLenFeature([], tf.int64), |
| 'steps/observation/image': tf.io.VarLenFeature(tf.string), |
| 'steps/observation/state': tf.io.VarLenFeature(tf.float32), |
| 'steps/action': tf.io.VarLenFeature(tf.float32), |
| 'steps/reward': tf.io.VarLenFeature(tf.float32), |
| 'steps/is_first': tf.io.VarLenFeature(tf.int64), |
| 'steps/is_last': tf.io.VarLenFeature(tf.int64), |
| 'steps/language_instruction': tf.io.VarLenFeature(tf.string), |
| } |
| return tf.io.parse_single_example(serialized, features) |
| |
| dataset = dataset.map(parse_episode) |
