tf api usage : stop_if_no_decrease_hook

will be helpful for those in need I wanna use stop_if_no_decrease_hook tf api in object detection.
code :
import numpy as np
import tensorflow as tf
import logging
from tensorflow.python.training import session_run_hook

class EarlyStoppingHook(session_run_hook.SessionRunHook):
"""Hook that requests stop at a specified step."""

  def __init__(self, monitor='val_loss', min_delta=0, patience=0,
             mode='auto'):

    self.monitor = monitor
    self.patience = patience
    self.min_delta = min_delta
    self.wait = 0
    if mode not in ['auto', 'min', 'max']:
        logging.warning('EarlyStopping mode %s is unknown, '
                        'fallback to auto mode.', mode, RuntimeWarning)
        mode = 'auto'

    if mode == 'min':
        self.monitor_op = np.less
    elif mode == 'max':
        self.monitor_op = np.greater
    else:
        if 'acc' in self.monitor:
            self.monitor_op = np.greater
        else:
            self.monitor_op = np.less

    if self.monitor_op == np.greater:
        self.min_delta *= 1
    else:
        self.min_delta *= -1

    self.best = np.Inf if self.monitor_op == np.less else -np.Inf

def begin(self):
    # Convert names to tensors if given
    graph = tf.get_default_graph()
    self.monitor = graph.as_graph_element(self.monitor)
    if isinstance(self.monitor, tf.Operation):
        self.monitor = self.monitor.outputs[0]

def before_run(self, run_context):  # pylint: disable=unused-argument
    return session_run_hook.SessionRunArgs(self.monitor)

def after_run(self, run_context, run_values):
    current = run_values.results

    if self.monitor_op(current - self.min_delta, self.best):
        self.best = current
        self.wait = 0
    else:
        self.wait += 1
        if self.wait >= self.patience:
            run_context.request_stop()

extracting CPU usage,Memory usage and network utilization using java on windows/linux

I hope this helps you . Memory used refer to the allocated memory size, actual memory used is the one which is actually used out of the allocated, it reduces some kernel and other areas memory from it.
For CPU, I also figured out values to be different and seen some blog where it suggest to multiply by 100. So I did, now the values are quite similar... http://code.google.com/p/starfire/source/browse/trunk/starfire/src/main/java/es/upm/dit/gsi/starfire/capability/systemMonitor/CpuMonitor.java?spec=svn279&r=279

hop of those help? NSPhotoLibraryUsageDescription is not Camera Usage. It is Photo Library usage. You still have not done what the error message is telling you to do. Add a Photo Library usage key-value pair to your Info.plist.

Get the memory usage, CPU usage, disk usage in windows 10 UWP C#

it should still fix some issue We can use the MemoryManager class, it provides access to information on an app's memory usage. And we can use ProcessDiagnosticInfo.CpuUsage and ProcessDiagnosticInfo.DiskUsage to get CPU usage, disk usage in current process.
ProcessCpuUsage class has no constructor, it provides access to data about the CPU usage of a process. And this class only has a GetReport method, which gets the ProcessCpuUsageReport for the process. With ProcessCpuUsageReport class, we can get KernelTime and UserTime consumed by the process.

around this issue I am the one who implemented the OSProcess class in OSHI that you are referencing, and have been communicating with you in an Issue on that project.
While OSHI does not currently provide all the functionality in the OSProcess interface, it does provide you access methods to the WMI classes which will provide you all the information you seek. If you take a look at the WindowsOperatingSystem class which implements the getProcess() method you're using, you can copy/modify the code using WMIUtil to directly fetch the bits of information that you need.

C++ warning when container destroyed/modified before its usage (usage via reference to an element or an iterator)

this one helps.
Is there a way to have compiler errors/warning while using an iterator/any reference to a container item after container modification (enlarges/shrinks)/destruction?
