[project SDK is not defined] error resolution

Error analysis:

First of all, read the reason for the error. The error message shows that the project SDK is not defined. It prompts me to install the SDK. Some novice friends are a little confused at this time. They only know that JDK is a java development kit. So what is the SDK? I have never used it before. How can I prompt me to install it at this time. At this time, don’t worry, guys. In fact, SDK refers to the software development kit (abbreviation: SDK, full name of foreign language: software development kit). It is generally a collection of development tools used by some software engineers to build application software for specific software packages, software frameworks, hardware platforms, operating systems, etc. here, SDK refers to our JDK, that is to say, this The project could not find the dependent JDK. At this time, we go to check the project environment configuration and find the following situation:

Sure enough, there is a problem with the JDK environment configuration, and then the problem is solved by choosing our JDK environment path.

In the above error log, we know which 9-patch images are problematic, and then find them one by one. The operation is as follows:

Hold down Ctrl or shift, click the left mouse button, and adjust the black part on the boundary pixel until we need the area and do not report an error.

After the completion of sync, clean it.

Tensorflow tf.train.exponential_ Decay function (exponential decay method)

one

In tensorflow, exponential decay method is provided to solve the problem of setting learning rate.

adopt tf.train.exponential_ The decay function realizes the exponential decay learning rate.

Steps: 1. First, use a larger learning rate (purpose: to get a better solution quickly);

Secondly, the learning rate is gradually reduced by iteration;

Code implementation:

[html]

view plain

copy

decayed_ learning_ rate=learining_ rate*decay_ rate^(global_ step/decay_ steps)

Among them, decayed_ learning_ Rate is the learning rate used in each round of optimization;

learning_ Rate is the preset initial learning rate;

decay_ Rate is the attenuation coefficient;

decay_ Steps is the decay rate.

and tf.train.exponential_ For the decay function, you can use the stair case (the default value is false; when it is true, the global_ step/decay_ Steps) are converted to integers, and different attenuation methods are selected.

Code example:

[html]

view plain

copy

global_ step = tf.Variable (0) learning_ rate = tf.train.exponential_ decay(0.1, global_ Step, 100, 0.96, stair case = true) # generating learning rate # learning_ step = tf.train.GradientDescentOptimizer (learning_ rate).minimize(….., global_ step=global_ Step) # use exponential decay learning rate

learning_ Rate: 0.1; stair case = true; then multiply by 0.96 after every 100 rounds of training

Generally, the setting of initial learning rate, attenuation coefficient and attenuation speed is subjective (i.e. empirical setting), while the decreasing speed of loss function is not necessarily related to the loss after iteration,

So the effect of neural network can’t be compared by the falling speed of loss function in previous rounds.

two

tf.train.exponential_ decay(learning_ rate, global_ , decay_ steps, decay_ rate, staircase=True/False)

For example:

[python]

view plain

copy

import tensorflow as tf; import numpy as np; import matplotlib.pyplot as plt; learning_ rate = 0.1 decay_ rate = 0.96 global_ steps = 1000 decay_ steps = 100 global_ = tf.Variable ( tf.constant (0)) c = tf.train.exponential_ decay(learning_ rate, global_ , decay_ steps, decay_ rate, staircase=True) d = tf.train.exponential_ decay(learning_ rate, global_ , decay_ steps, decay_ rate, staircase=False) T_ C = [] F_ D = [] with tf.Session () as sess: for i in range(global_ steps): T_ c = sess.run (c,feed_ dict={global_ : i}) T_ C.append(T_ c) F_ d = sess.run (d,feed_ dict={global_ : i}) F_ D.append(F_ d) plt.figure (1) plt.plot (range(global_ steps), F_ D, ‘r-‘) plt.plot (range(global_ steps), T_ C, ‘b-‘) plt.show ()

Analysis:

The initial learning rate is 0.1, and the total number of iterations is 1000. If stair case = true, it means every decade_ Steps calculates the change of learning rate and updates the original learning rate. If it is false, it means that each step updates the learning rate. Red means false and green means true.

results:

UIStackView before iOS 9.0

A friend encountered a problem today ＂ uistackview before IOS 9.0 ＂

This is because uistackview cannot be used under IOS 9. The solution is stack flow

Check inProject Targets-> Deployment info -> Deployment Target.If it’s not 9.0 change it to 9.0.

You need to change the deployment target of your application’s target to iOS 9. Otherwise the app supports down to whatever OS that your deployment target is set to.

Not solved?? Check out for other reason??? Check this:

If your Deployment target is already set to 9.0 and you still get this error then try then check your project File inspector-> Project Document -> Project Format and check if its Xcode-6.3-compatible or not.If its not then set it to Xcode-6.3-compatible.

The other reason is may be you accidentally add UIStackView and thats why you encounter the problem. UIStackView supports 9.0 and later and your deployment target doesn’t allow that. So just check if you accidentally add UIStackView and if you added and you don’t want it than just remove it.

2. To use uistackview under IOS, someone has mined this method.

Why can I use uistackview under IOS 9 through fdstackview

The following results are the test conclusions.

Isactive in hierachy is equivalent to whether a GameObject is active or not, which is the same as a simple understanding.

Isactive andenabled requires three conditions:

The isactiveinheerachy of

GameObject is true, and onenable is being or has been called

So:

in onenable of a script, isactive andenabled is always true. In ondisable of a script, isactive andenabled is always false

Test example: place a GameObject in the scene and two scripts below. Set GameObject and scripts to be active. In the process of running the scenario, in the script that calls onenable first, you can find that your isactive andenabled is true, but another script’s isactive andenabled is false.

So: there is no script to call onenable, though gameObject.isActiveInHierachy Is true, and enabled is true, but isactive andenabled is false.

Today, as always, I opened the web page. At first, there was nothing wrong with it, and then it suddenly appeared:

An error occurred.

Sorry, the page you are looking for is currently unavailable.
Please try again later.

If you are the system administrator of this resource then you should check the error log for details.
Faithfully yours, nginx.

Is it a familiar mistake?

Check out the error page of nginx.

This 50x. Html is found to be the error on the web page.

Then check the port
through the command: netstat – tnlp to view the opened TCP port.
Found that the 9000 port PHP is not on.
Then restart the PHP service, and the problem is solved.
