WKWebView needs to be reloaded on a particular occasion, but goes directly back to the failed proxy method and reports the following error
Error Domain=WebKitErrorDomain Code=102 “Frame load interrupted”
After looking through the data and testing it, the conclusion is that WebView can reload and succeed when it loads links like “http:\\www.baidu.com”, but loading HTML data is unsuccessful and has not been solved yet.The way to solve the problem remains to be verified.
Summary
Not many people have a thorough understanding of the internal structure and patterns of GPIO (General Purpose Input and Output) processors. Recently, Baidu has searched for a large amount of information on this part, and there is no consensus on many of these issues.This article lists all the questions that IO involves as far as possible, explains clearly the questions that have definite answers, and puts forward the questions where there are still questions for discussion.
Generally speaking, IO’s functional modes can be roughly divided into three categories: input, output and ...
Potentiometers are often used for parameter calibration, such as adjustable power supply, amplifier gain regulation, adjustable filter, LCD backlight regulation, noise-free adjustment of sound, etc. There are mechanical and digital types.
Mechanical advantages are: fixed after power on, high voltage and high current resistance, but poor temperature characteristics, greatly affected by mechanical vibration
Electronic: digital control can be changed, good stability, good temperature characteristics, the shortcomings are narrow voltage and current range, narrow bandwidth. The output range and cu...

First, an overview
When it comes to concurrency, you have to talk about ReentrantLock; when it comes to ReentrantLock, you have to talk about AbstractQueued Synchronizer (AQS)!
Class is its name.Abstract queue synchronizer，AQSA set of definitions is defined.Multithreaded access to shared resourcesSynchronizer framework，Many synchronous class implementations rely on it.，Such as commonly used ReentrantLock/Semaphore/CountDownLatch…。

After we train the model with keras, we usually save the model format type as hdf5, that is. H5 file.
But if we want to migrate to the mobile end, especially the one supported by tensorflow, we need to convert it to tflite.
How to convert? In tensorflow1.9 and above versions, it is convenient to convert by command line.
tflite_convert --output_file=/home/yourname/Documents/tensorflow/images/500pics2/model/my_model.tflite --keras_model_file=/home/yourname/Documents/tensorflow/images/500pics2/model/my_model.h5

My computer has several versions of jdk, JDK1.6 and jdk1.8, but my environment variables are set to jdk1.6. However, opening CMD to see Java version shows 1.8, which makes me puzzled. Later, problems were discovered.
Problem: under the path variable, JDK1.8 automatically generates variables for us, covering 1.7 of the original version.
Solution: 1. remove the C:\ProgramData\Oracle\Java\javapath in the path variable.
2.Move the%JAVA_HOME%/bin in the environment variable Path to the front end.
At this time, the Java -version again in CMD will display the information o...
