If you want to delete an element in an array, you can use the unset directly, but what I see today is a surprise to me. $arr = Array (' A ', ' B ', ' C ', ' d ');Unset ($arr [1]);Print_r ($arr);?>Print_r ($arr) After that, the result is not that, the end result is Array ([0] => a [2] => C [3] => D) So how do you get the missing elements to be filled and the array will be indexed again? The answer is Array_splice (): $arr = Array (' A ', ' B ', ' C ', ' d ');Array_splice ($arr, 1, 1);Print_r

usage of the byte stream and the character stream is the same, the difference is that the byte stream and the character stream operate the different data units--byte stream operation is 8 bits of bytes, character streamThe operation is a 16-bit character. Byte stream mainly consists of InputStream and OutputStream as base class, while character stream is mainly composed of reader and writer as base class.node stream and process flow: a node stream to read and write data from a specific data sou

: after loading the persistence model, there is no V1 variable node in the calculation diagram.At the same time, you use the v1=tf.get_variable (name= "v1", Shape=[1]) method to generate a new variable node v1_1 in the current code's calculation diagram, not the variable node V1 in the loaded persistence model. In this case, the function function is invalidated . That is, you want to invoke the Get_variable function so that the Python variable v1 and the variable node v1 in the calculation diagr
