Tensorflow:TypeError: pred must not be a Python bool

這個問題常見且不小心就會遇到,記錄下O(∩_∩)O哈！

TypeError: pred must not be a Python bool

貼出一段先嚇一下小夥伴們,有些小夥伴可能剛接觸代碼沒有很久,碰到error就會非常煩躁,甚至直接就give up了,但是作爲祖國花朵的我們怎麼能說放棄就放棄呢?其實看着這段報錯很嚇人,有用的只有最後一行!!

TypeError: pred must not be a Python bool

其實就是個類型錯誤,或者不兼容的問題,
LZ直接定義is_training = True,因爲定義的is_training=True不是tf.bool類型,所以導致不兼容,只要定義的時候加上type就行了,舉個例子:

is_training = tf.cast(True, tf.bool)

調代碼就還是得慢慢來,切勿心浮氣躁,小夥伴們加油!哈哈,順便祝下自己生日快樂,Felaim每天要加油,開心O(∩_∩)O~~
