Getting error "tensorflow.python.framework.errors_impl.InternalError: Failed to create session"

[kapitsa2811]

When I run the code I get an error at line

    estimator.train(input.input_fn(train_input,
                                   input_label_dir=train_labels_input,
                                   num_epochs=training_params.evaluate_every_epoch,
                                   batch_size=training_params.batch_size,
                                   data_augmentation=training_params.data_augmentation,
                                   make_patches=training_params.make_patches,
                                   image_summaries=True,
                                   params=_config,
                                   num_threads=32))

The error is:
