问题 I'm using JSON Spirit to parse and generate json. I cannot use using namespace json_spirit because another library uses conflicting names.

Tensorflow: how to swap variables between scopes and set variables in scope from another

由 折月煮酒 提交于 2019-12-11 07:55:57
问题 I have different scopes and they have variables with same names but with different values. I want to swap values of these variables between scopes. Example: with tf.variable_scope('sc1'): a1 = tf.Variable(0, name='test_var1') b1 = tf.Variable(1, name='test_var2') with tf.variable_scope('sc2'): a2 = tf.Variable(2, name='test_var1') b2 = tf.Variable(3, name='test_var2') I want to set a2 to 0, b2 to 1, a1 to 2 and b1 to 3. I was thinking about getting needed variables with tf.get_collection_ref

How does variable scoping work in a POE session?

由 元气小坏坏 提交于 2019-12-11 07:49:12
问题 Can anyone explain how variable scoping works within a POE session? What is the proper way to pass state within the session, without impacting other sessions? Thanks Josh 回答1: Scoping is unaffected by POE. You can use POE's heap (accessible through $_[HEAP] ) to pass data around between your various handlers. According to the docs, the heap is distinct between sessions by default, but it is possible to override this so that different sessions share a heap. sub my_state_handler { $_[HEAP]{some

问题 I have an ErrorLog class, that is used to write and modify log files. I'd like to write to it before and after major events for debugging purposes and I only want to use one instance of the ErrorLog class for the entire application. I tried declaring an ErrorLog object as a global by placing ErrorLog exe_log; into a header file so it is accessbile to other files, but I keep getting an error saying it is already defined. Is there a correct way to defing global objects? 回答1: You need a

PHP Variable Scope

问题 Is there a way to declare a variable so it is available in all functions. Basically I want to call: Global $varName; automatically for every function. And no, I can't use a constant. I don't think its possible but wanted to ask anyway. Thanks! :D 回答1: That's pretty oldschool and not recommended. If you want to use variables whereever you want consider using sessions of passing through variables if you're on an object oriented tour ;) 回答2: There is a $GLOBALS variable and a globals keyword
