TensorFlow: generating a random constant

阅读更多关于 TensorFlow: generating a random constant

问题 In ipython I imported tensorflow as tf and numpy as np and created an TensorFlow InteractiveSession . When I am running or initializing some normal distribution with numpy input, everything runs fine: some_test = tf.constant(np.random.normal(loc=0.0, scale=1.0, size=(2, 2))) session.run(some_test) Returns: array([[-0.04152317, 0.19786302], [-0.68232622, -0.23439092]]) Just as expected. ...but when I use the Tensorflow normal distribution function: some_test = tf.constant(tf.random_normal([2,

Get active sessions with wmi (Win32_LogonSession returns also inactive/old sessions)

阅读更多关于 Get active sessions with wmi (Win32_LogonSession returns also inactive/old sessions)

问题 Is there a way to show only active sessions with wmi? The problem is that Win32_LogonSession shows also inactive/disconnected sessions. ManagementScope scope = new ManagementScope(ManagementPath.DefaultPath); SelectQuery query = new SelectQuery("Win32_LogonSession"); ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query); ManagementObjectCollection results = searcher.Get(); foreach (ManagementObject mo in results) { PrintWmiObject(mo); } The output of this is something

Is there a way to automatically suppress Matlab from printing big matrices in command window?

阅读更多关于 Is there a way to automatically suppress Matlab from printing big matrices in command window?

问题 Is there an option in matlab or a plugin/app or a trick such that if you are in an interactive command session, every time it would print out a matrix way too big for a human to look through, it redacts the output to either a warning of how big the matrix is or a summary (only a few rows and columns) of the matrix? There are many times where I want to examine a matrix in the command window, but I didn't realize how big it was, so I accidentally printed the whole thing out. Or some place

How to save a Python interactive session?

阅读更多关于 How to save a Python interactive session?

问题 I find myself frequently using Python\'s interpreter to work with databases, files, etc -- basically a lot of manual formatting of semi-structured data. I don\'t properly save and clean up the useful bits as often as I would like. Is there a way to save my input into the shell (db connections, variable assignments, little for loops and bits of logic) -- some history of the interactive session? If I use something like script I get too much stdout noise. I don\'t really need to pickle all the
