[Solved] SpringBoot Error: Caused by: org.yaml.snakeyaml.error.YAMLException: java.nio.charset.Malforme

Springboot error prompt application YML error

The main error messages are as follows:

Caused by: org. yaml. snakeyaml.error.YAMLException: java.nio.charset.Malforme

Caused by: org.yaml.snakeyaml.error.YAMLException: java.nio.charset. MalformedInputException: Input length = 1

I don’t understand the meaning of the second sentence now, but because I modify the application directly The suffix of the properties file has been changed to application yml

Solution:

Create a new file: application.yml, and then copy the old content, it is done!

Cause analysis

I previously delegated the build of the code to Maven through setup.

So when I click Run, idea will not use the built-in build function to build, but use Maven to build.

When you click the run configuration, you will find that the behavior before startup is build .

Looking at the log, we can see that Maven will only build the current module, so the dependencies of other modules cannot be found.

Solution:

Modify the run configuration and build project before running.

Click Run. You can see from the log that Maven has built other modules. The problem has been solved.

[Solved] java.io.IOException: error constructing MAC: java.lang.SecurityException: JCE cannot authenticate the provider BC

[Solved] DCNv2 Compile Error: error: identifier “THCudaBlas_SgemmBatched” is undefined

Solution:

Reduce pytorch version to 1.7.0;

#Uninstall the original torch and torch vision first

pip uninstall torch
pip uninstall torchvision

#Install pytorh1.7

pip install torch==1.7.0+cu110 torchvision==0.8.1+cu110 -f https://download.pytorch.org/whl/torch_stable.html

Recompile.

Pytorch Install Error: OSError: [WinError 126] Could not Find the Module, Error loading “xx\lib\site-packages\torch\lib\asmjit.dl 

conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch

The installation can be completed normally, but an error occurred in the import torch vision:

C:\Users\xuyic\anaconda3\envs\pytorch\lib\site-packages\torchvision\io\image.py:11: UserWarning: Failed to load image Python extension: [WinError 126] 找不到指定的模块。
  warn(f"Failed to load image Python extension: {e}")

Solution:

1. From cuda10.2 to 11.3

2. Reduce the version of torchvision, such as 1.3.0

VBox install Ubuntu 16.04 shared folder suddenly fails Error: error: unrecognized command line option ‘- fstack protector strong’

Cause investigation

#gcc -v

Found version 4.7.7

but

Installing the above enhanced software requires the gcc5.0 provided with 16.04 Version 4

Solution:

1  sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 100
2  sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 50
3  sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-5 100
4  sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.7 50
Then Re-install
#./autorun.sh
Done!

[Solved] typescript:error TS2531: Object is possibly ‘null’.

Why? Yes, the TS compiler diagnosed document at compile time Getelementbyid (‘test ‘) may be null, so a prompt is given: the object may be null. The solution is as follows:

document.getElementById('test')!.innerHTML = greeter(user);

Add one!, What does the exclamation point mean?It is actually a not null assertion operator. It does not perform runtime check and tells the compiler that it only needs to know this thing
