问题 How do you pass a parameter to an Azure CLI Task in Azure DevOps? Take the very basic example of showing basic info about a VM. A basic CLI command would be: az vm show --name myVM --resource-group dev -o table Now if I wanted to parameterize that command, so that I could pass in the VM Name, who would i do it? I've tried creating a CLI Task as both an in-line script and a file, passing parameters using the Azure DevOps Argument builder, but nothing seems to work. The parameter looks like

问题 I'm training a VGG-16 model from scratch using a dataset containing 3k images. I use Tensorflow platform and 8 cpus without any gpu. Training rate - 0.01, Weight decay - 0.0005, Momentum - 0.9, Batch size - 64, I've kept training for about three days. But the training accuracy has been unchanged, around 15%-20% after 20 epochs. Could anyone give me some hints to improve the accuracy? 回答1: It seems like I have used too large learning rate. Or weight decay does not work as it promises. After I

问题 in variable-length parameters function, the '...' must be place last. And default value enabled parameters must be last, too. so, how about both needed in the same one function? Now I have a log utility: void MyPrint(int32_t logLevel, const char *format, ...), which used to print log according to 'logLevel'. However, sometimes I hope it can be used as: MyPrint("Log test number%d", number), without 'logLevel' needed. The question: Default arguments and variadic functions didn't help. 回答1: In

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Does Java support default parameter values? Suppose I want to make default parameter value in C++, then we can express it as below. void functionName(char *param1, int param2=2); But if I want to make this in Java, then is it possible. Currently I am doing as below public functionName(String param1) { this(param1, 2); } public functionName(String param1, int param2) { .......... } 回答1: It is not possible in Java

问题 In pgadmin3, I would like to use parameterized queries (to faster debugging, just copy & paste the query from my php file). But I haven't found an option to add the values of the $1 , $2 ... parameters. Is it possible? This is the query I'm building in a loop, following the suggestion for NULL testing from here: SELECT EXISTS(SELECT 1 FROM tax WHERE (addby=$1 or addby<>$1) AND (adddate=$2 or adddate<>$2) AND ($3 IS NULL AND nome IS NULL OR nome=$3) AND ($4 IS NULL AND rank IS NULL OR rank=$4)
