The $me variable was initially an Int32, but Windows PowerShell changed it to a String when the value "Don" was added. Windows PowerShell can change the type of a variable as needed, provided the variable hasn't already been explicitly set to a specific type. ...
There is already a pipeline set up that does training and evaluation, and it is easy to execute training and prediction jobs for various models of interest. The appropriate metrics have been selected and implemented. These should be as representative as possible of what would be measured in the...
On scale setups, if you send generic class queries to the Cisco APIC that result in a large set of managed objects, the queries intermittently fail due to a timeout with error code 503 and the following error message: ...
I use the AddInParameter method of the DBCommandWrapper to set the values of the parameters that I used in the UPDATE SQL statement. I could have used the AddParameter method as well, which allows a little more flexibility since you can specify the direction. However, in this case the Add...
