TypeError: Value passed to parameter 'shape' has DataType float32 not in list of allowed values: int32, int64
 

Solution

將x或者x.values轉換為dtype # tensor a is [1.8, 2.2], dtype=tf.float # tf.cast(a, tf.int32) ==> [1, 2]，dtype=tf.int32 tf.cast(x, dtype, name=None)

將傳給shape的變數變成int32的==》tf.cast(shape, tf.int32)
