Question

张量流，我读不到字符串，长，只允许短浮点数？为什么？

import tensorflow as tf
import numpy as np

# Data sets
IRIS_TRAINING = "seRelFeatures.csv"
IRIS_TEST = "seRelFeatures.csv"

# Load datasets.
training_set = tf.contrib.learn.datasets.base.load_csv(filename=IRIS_TRAINING, target_dtype=np.int)
test_set = tf.contrib.learn.datasets.base.load_csv(filename=IRIS_TEST, target_dtype=np.int)

这是错误

ValueError: invalid literal for long() with base 10: ''

Answer 1

您的错误是ValueError: invalid literal for long() with base 10: ''。它只是输入空字符串而不是整数（或整数的字符串表示）。我会检查CSV文件中的数据。

Answer 2

其实我自己解决了这个问题，这个错误意味着

ValueError: invalid literal for long() with base 10: ''

我有一些空单元格，但实际上我没有查看。我检查后，它通过我删除最后一列，但我只是删除内容没有删除单元格，所以从视图中找不到任何空
