背景：

在使用tensorflow2.x的时候,当使用tf.linspace的时候会出现如下的报错：

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

import tensorflow as tf
from tensorflow import keras
import numpy as np

def out():
    # x = tf.constant(np.arange(12).reshape(2,6))
    x = tf.linspace(-6 , 6, 12)
    print(x)
    target = tf.sigmoid(x)
    print(target)


def __test_out__():
    out()


if __name__ == '__main__':
    __test_out__()

 解决方案：

查看官方文档：

https://www.tensorflow.org/api_docs/python/tf/linspacehttps://www.tensorflow.org/api_docs/python/tf/linspace

上面说的很清楚，start、stop必须是float类型的，

因此，代码修改如下：

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

import tensorflow as tf
from tensorflow import keras
import numpy as np

def out():
    # x = tf.constant(np.arange(12).reshape(2,6))
    x = tf.linspace(-6. , 6., 12)
    print(x)
    target = tf.sigmoid(x)
    print(target)


def __test_out__():
    out()


if __name__ == '__main__':
    __test_out__()

正常运行！！！
