Error in Tensorflow 2.5.0 while using Colab TPU - NotFoundError: Could not find metadata file. [Op.DatasetCardinality]
Error in Tensorflow 2.5.0 while using Colab TPU - NotFoundError: Could not find metadata file. [Op.DatasetCardinality]
注意:这些相同的步骤在 Colab GPU 上没有任何错误。
请帮我解决这个问题。我创建了一个数据集并将其保存为文件
data = tf.data.Dataset.from_tensor_slices(( features, labels))
tf.data.experimental.save(data, myfile)
当我尝试加载它时
data = tf.data.experimental.load(myfile)
和 运行 数据上的任何函数,如 len(data)
、data.batch(16)
或 data.take(1)
然后我得到这个错误:
NotFoundError: Could not find metadata file. [Op:DatasetCardinality]
TPU 配置
resolver = tf.distribute.cluster_resolver.TPUClusterResolver(tpu='')
tf.config.experimental_connect_to_cluster(resolver)
# This is the TPU initialization code that has to be at the beginning.
tf.tpu.experimental.initialize_tpu_system(resolver)
是否与此类似TF1.14][TPU]Can not use custom TFrecord dataset on Colab using TPU?
经过更多调试后我得到了这个错误:
UnimplementedError: File system scheme '[local]' not implemented (file: './data/temp/2692738424590406024')
Encountered when executing an operation using EagerExecutor. This error cancels all future operations and poisons their output tensors. [Op:DatasetCardinality]
我找到了这个解释:
云 TPU 只能访问 GCS 中的数据,因为只注册了 GCS 文件系统。
