Problem Description: my project was fine the day before yesterday. Suddenly, the following error was reported after opening it the next day
Error:Kotlin: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.16.
I didn’t use kotlin either. Finally, I recompiled the project when compiling
Done!
Error Messages:
Errorjava Compilation failed internal java compiler error
Solution:
1. view the project’s jdk (Ctrl+Alt+shift+S)
File ->Project Structure->Project Settings ->Project
2, view the project’s jdk (Ctrl+Alt+shift+S)
File ->Project Structure->Project Settings -> Modules -> (Name of the project to be modified) -> Sources ->
3. View Java configuration in idea
File ->Setting ->Build,Execution,Deployment -> Compiler -> Java Compiler
If the above three steps still fail
Clear IDEA cache Restart IDEA
File->Invalidate Caches/Restart

In the win7 system, under the command terminal, the two methods of installing pycallgraph report the exception of subprocess exited with error
Solution: downgrade setuptools
1. First check the current version of setuptools.
pip show setuptools
2. The version of setuptools has been downgraded. Here, I downgraded it to 57.5.0
pip install --upgrade setuptools==57.5.0
3. Try installing pycallgraph again

Problem description: When generating a dataloader, the training set can be run, but the test set has this error: RuntimeError: stack expects each tensor to be equal size, but got [200] at entry 0 and [116] at entry 1.
How to Solve: In generating the dataloader, I need to generate a dataset, so my error occurred because there is a minibatch in the dataset with a different number of data than the other minibatch, so I went into the custom dataset method to check, and through print debugging, I found that it was a problem with the dataset label.
Solution: Go into the dataset and print the output of the dataset.

After looking for the reason for a long time, I finally found that the final error was due to the wrong version of GCC and G + +. After changing GCC and g++ 5.5.0, I successfully compiled
Process for installing GCC and g++ version 5.5.0:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5
sudo apt-get install g++-5Change GCC and g++ versions
cd /usr/bin
sudo rm gcc
sudo ln -s gcc-5 gcc
sudo rm g++
sudo ln -s g++-5 g++Finally, check whether the modification is successful
gcc --version
g++ --versionRecompile:
catkin_make clean #Clear the front compile
catkin_make Problem Description:
The project started well in the morning, but not in the afternoon 😂 What is this situation… At first, the project could not be started because the HTTP resources would be filtered out after Maven version 3.8.1. Later, it was still impossible to change HTTP to HTTPS,
The best way is to modify the Maven version. I changed it to Maven version 3.6.3. After that, I can download the package. However, it didn’t take long before there was another problem. Malformed \uxxxx encoding.
Let’s start with this error report today: malformed \ uxxxx encoding (the problem encountered today has been solved for half an afternoon and the reason has finally been found…)
Solution Summary:
First of all, the solutions are nothing more than the following:
1, first check the project .properties, .yml, pom.xml, logback and other configurations, whether there is a path error in the use of
2, update the maven repository, re-download the jar package
3, delete the path-to-the-library or resolver-status.properties file
In either case, it is recommended to restart the editor. For idea, click the Invalidate Caches/ Restart button to clear the cache and restart the idea
After opening IDEA and updating the project to start.
1, suddenly found build failure reported a strange error: Malformed \uxxxx encoding.
2. The <project> tag in the pom.xml file is also marked in red with the error.
But but but the code in the pom is exactly the same as on master, others are fine, but not their own, some of the import classes in the file will also report an error Can’t find.
Reason: When updating the jar packages that the project depends on, the downloaded jar packages may be incomplete due to network problems.
Solution: Delete the downloaded jar package and download it again.
In fact, it is not necessary to delete and re-download the package in general, so I think there must be a way to find the problematic package. To do accurate deletion
The quick solution is:
# Use the -X parameter to type out the error file information
mvn pakage -X
# Check the log, then delete or change the name of the file with the error to something else
# This will allow you to re-download the wrong fileI solved this problem through method 3
(1) In the . /m2/ folder (modify as you see fit), find path-to-the-library and delete it (if this file is not present, you can simply ignore this step).
(2) In the . /m2/repository (modify according to your situation) folder, search globally for the file: resolver-status.properties, delete all the files found, and recompile.

Solution:
Runtime problems
Permission Denied | Can not find directory…
Problem Analysis: The command is incorrectly run with the root user when git clone or install dependencies, resulting in the personal user not having any modification rights.
Solution: In the root directory of OpenFPGA
sudo chown -hR {user name}:{user group, usually same as user name} . /
# Change all file owners to individual users
In the yosys shell, when the show command views the circuit diagram, it prompts an error
Problem: lack of dot matrix graphic display tool
solution: try running sudo apt-get install xdot
The first problem encountered was that the BR file could not be found
Log: unresolved reference: BR
Reason: the plug-in developed by kotlin does not support cross module, so the reference of databinding when using APT Technology br file does not determine the directory, so the error (unresolved reference: be) is caused, so it needs to be completed by kapt
Solution:
apply plugin: 'kotlin-kapt'
kapt {
generateStubs = true
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
//The version should be the same as the gradle version
kapt "com.android.databinding:compiler:3.5.0"
}New problem: Class not found Custom generated class can not be generated.
Reason: If you already have kapt, you need to replace it with kapt
Solution: In Kotlin, you need to add the kotlin-kapt plugin to activate kapt and replace the annotationProcessor with kapt.
ArrayList.add() and aslist().add() problem
using aslist().add() report an error: UnsupportedOperationException
Cause and analysis
asList() is using the internal class ArrayList of Arrays, this internal class does not override the add() method, so the add method used here is the parent class abstract class of the ArrayList class, the add() method here by default is to throw an exception: UnsupportedOperationException
Internal class of arrays
private static class ArrayList<E> extends AbstractList<E>
implements RandomAccess, java.io.Serializable
{
private static final long serialVersionUID = -2764017481108945198L;
private final E[] a;
ArrayList(E[] array) {
a = Objects.requireNonNull(array);
}
@Override
public int size() {
return a.length;
}
@Override
public Object[] toArray() {
return a.clone();
}
@Override
@SuppressWarnings("unchecked")
public <T> T[] toArray(T[] a) {
int size = size();
if (a.length < size)
return Arrays.copyOf(this.a, size,
(Class<?extends T[]>) a.getClass());
System.arraycopy(this.a, 0, a, 0, size);
if (a.length > size)
a[size] = null;
return a;
}
@Override
public E get(int index) {
return a[index];
}
@Override
public E set(int index, E element) {
E oldValue = a[index];
a[index] = element;
return oldValue;
}
@Override
public int indexOf(Object o) {
E[] a = this.a;
if (o == null) {
for (int i = 0; i < a.length; i++)
if (a[i] == null)
return i;
} else {
for (int i = 0; i < a.length; i++)
if (o.equals(a[i]))
return i;
}
return -1;
}
@Override
public boolean contains(Object o) {
return indexOf(o) != -1;
}
@Override
public Spliterator<E> spliterator() {
return Spliterators.spliterator(a, Spliterator.ORDERED);
}
@Override
public void forEach(Consumer<?super E> action) {
Objects.requireNonNull(action);
for (E e : a) {
action.accept(e);
}
}
@Override
public void replaceAll(UnaryOperator<E> operator) {
Objects.requireNonNull(operator);
E[] a = this.a;
for (int i = 0; i < a.length; i++) {
a[i] = operator.apply(a[i]);
}
}
@Override
public void sort(Comparator<?super E> c) {
Arrays.sort(a, c);
}
}
Add method of ArrayList() class
public boolean add(E e) {
ensureCapacityInternal(size + 1); // Increments modCount!!
elementData[size++] = e;
return true;
}
Add method of AbstractList class
Aslist() uses this method
public void add(int index, E element) {
throw new UnsupportedOperationException();//This is where the exception is thrown
}[Solved] Vue Error: Error in v-on handler (Promise/async): “[object object]“
Solution:
Use try_ catch package async… await function
/**
* export

async download () { // export
try {
const { parkName } = this.formInline
const res:any = await exportInvoice({ parkName })
this.downSteam(res)
