tenforflow model prediction

[reclock]

Currently, I am using Tenforflow for image recognition testing, and this is my code and error

train_ds = tf.keras.utils.image_dataset_from_directory(
  data_dir,
  validation_split=0.2,
  subset="training",
  seed=123,
  image_size=(img_height, img_width),
  batch_size=batch_size)

val_ds_g = tf.keras.utils.image_dataset_from_directory(
  data_dir,
  validation_split=0.2,
  subset="validation",
  seed=123,
  image_size=(img_height, img_width),
  batch_size=batch_size)

SemLock and therefore the multiprocessing Python package are not supported in Gramine.

See:
