[英]TypeError: Input 'b' of 'MatMul' Op has type float32 that does not match type int32 of argument 'a' - even after casting
[英]TypeError: Tensors in list passed to 'values' of 'Pack' Op have types [string, float32] that don't all match. error from CSV tutorial
我在 TensorFlow 中获得了自己的训练数据等。 我从 Colab 上的 TensorFlow获得了Load CSV Data 教程,我更改了一些变量的配置以匹配我的数据。 当我运行程序时,我收到了这个错误:
/tensorflow-2.0.0/python3.6/tensorflow_core/python/autograph/impl/api.py in wrapper(*args, **kwargs)
235 except Exception as e: # pylint:disable=broad-except
236 if hasattr(e, 'ag_error_metadata'):
--> 237 raise e.ag_error_metadata.to_exception(e)
238 else:
239 raise
TypeError: in converted code:

raise TypeError("%s that don't all match." % prefix)
TypeError: Tensors in list passed to 'values' of 'Pack' Op have types [string, float32] that don't all match.
该块的整个输出可在 Pastebin 上获得。
教程中运行的块是:
packed_dataset = temp_dataset.map(pack)
for features, labels in packed_dataset.take(1):
print(features.numpy())
print()
print(labels.numpy())
我解决了我的问题。
我不小心忘记了我的第一列不是数字,所以我从列表中删除了它。
# Before Stuff
After Stuff
# SELECT_COLUMNS = ['sid', 'dist', 'microtime']
SELECT_COLUMNS = ['dist', 'microtime']
# DEFAULTS = ['a_r_d_b_id', 0.0, 0.0]
DEFAULTS = [0.0, 0.0]
temp_dataset = get_dataset(train_file_path,
select_columns=SELECT_COLUMNS,
column_defaults = DEFAULTS)
show_batch(temp_dataset)
example_batch, labels_batch = next(iter(temp_dataset))
def pack(features, label):
return tf.stack(list(features.values()), axis=-1), label
packed_dataset = temp_dataset.map(pack)
for features, labels in packed_dataset.take(1):
print(features.numpy())
print()
print(labels.numpy())
