Prerequisites

Premise: Make sure the dependencies in Maven are correct, Don’t make mistakes such as missing letters.
If you are worried, you can go to the official website to search, and copy and paste it again.
Official website link: https://mvnrepository.com/

scene

Importing a new project,or other reasons,maven refresh is also useless, it reports error as show below：

Solution:

1. First, Clear the cache, Click and restart IDEA.

2. Close IDEA, Open the project folder

Find .idea in the project, delete workspace.xml

3. Re-open IDEA， find Maven on the right

Find install under maven again, Double-click it and the download log shown below will appear.

Wait it over, and BUILD SUCCESS will appear:

Click the Reload button in the Maven component again, wait for the bottom progress bar to end

4. Solve the Dependencis report in Maven

First, Open the file pom.xml

Then delete the content in the tag dependencies [recommended to use Ctrl + x]

Click the Reload button in the Maven component again, wait for the bottom progress bar to finish. [dependencies disappears at this time]

Then in pom.xml, use the shortcut key Ctrl + z to return

（If you are using Ctrl + x ， you can use Ctrl + v to paste）

Let the dependencies content appear again，return to the previous state.

Final effect：

Finally, it is solved.

[Solved] ONNXImporter::handleNode DNN/ONNX和create layer “onnx::Gather_384“ of type “NonMaxSuppression“

Today I encountered a lot of OpenCV loading model errors when debugging the yolov7 model conversion and loading problemm There is no way to fully display it due to the title length limit, I will post it here in its entirety.

[ERROR:0] global D:\opencv-python\opencv\modules\dnn\src\onnx\onnx_importer.cpp (720) cv::dnn::dnn4_v20211004: :ONNXImporter::handleNode DNN/ONNX: ERROR during processing node with 5 inputs and 1 outputs: [NonMaxSuppression]:(onnx::Gather_384)

At this time, I think of a way to compare my own model with the official model one by one,Comparison of one node and one node, Finally found the problem at the end.

[Official Model]

[My own model]

Seeing this, I’m wondering if there is such a big difference?？It shouldn’t be，It’s all models built from the same code，So I started to trace the source，Sure enough Problem found.

At the position of my red frame, the official model ends here, and there is a large string of, tensor shapes for debugging both by printing, I guess that there may be a problem with the parameter settings during the model export process, So I tried to verify basically all the uncertain parameters, I found the problem.

In order to facilitate your understanding, I am giving my original conversion operation command here：

python export.py --weights best.pt --grid --end2end --simplify --topk-all 100 --iou-thres 0.65 --conf-thres 0.35 --img-size 640 640 --max-wh 640

This is the command after：

python38 export.py --weights best.pt --grid --simplify --topk-all 100 --iou-thres 0.65 --conf-thres 0.35 --img -size 640 640 --max-wh 640

See the difference, In fact, it is caused by the parameter end2end, After the modification, my model is as follows：

Because what I am doing here is the detection of the category, so the final output is: 1x25200x6, and the official one is: 1x25200x85.

Gephi cannot find Java 1.8 or higher [How to Solve]

Leave a reply

Previously installed Gephi and configured the Java environment, but not used for more than a year, recently opened Gephi reported an error:

cannot find Java 1.8 or higher

I followed the [online tutorial] to set the jdkhome variable in Gephi.conf as follows:

jdkhome="C:/Users/username/AppData/LocalLow/Oracle/Java/jdk11.0.9_x64& #34;

Another error was reported:

Cannot locate java installation in specified jdkhome

I read a bunch of posts on the Internet again, guess that my Java is not installed in the default path, but installed in the D drive, And the Gephi.conf file should only use Associate to the installation path of Java to, reconfigure：

jdkhome="D:/Program Files/JAVA sdk"

Gephi can be opened normally.

[Solved] Mac Notebook M1 Chip Install Hashlips library npm error

Mac notebook M1 chip installs Hashlips library npm error problem

Foreword

When generating NFT， we often prepare all the materials needed for NFT, and then stack each material on the same canvas to generate an NFT， but if we manually It’s too troublesome to stack one by one, because NFTs are often issued in thousands of ten thousand， so manual generation is unrealistic， So what can we do to generate It, Is to use the computer, There are many similar tools on the Internet, There are graphical and pure code, And many use Paython to generate NFT, But there is a node abroad The script tool Hashlips can directly use node to generate， and it is very convenient and powerful to use, There was no problem when using the windows system before, After changing the MBP later, I found that Hashlips reported an error when executing npm install

image-20220913144839078

Cause Analysis

After various searches and research, I found that Hashlip is implemented with canvas canvas, Then I touched the node-canvas library, There is a very similar problem in the issue of this library, which probably means that the Mac with m1 chip cannot directly use npm to install the library to node-canvas, You need to use Homebrewto install what you need.

image-20220913145139869

Solution

Official solution

In fact, both node-canvas and hasllips have released solutions one after another，The solution is actually the same，The following is hasllips The method approved in the official issue

The correct method is as follows:

1. Download and install Node.js "Current" version, as opposed to the "LTS" (Long Term Support) version. This is now v18.0.0 as of the time of this post , but 17.x will work as well:
2. Ensure you have homebrew installed. You can go to or just use this command: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install .sh)" to install Homebrew.
3. Install the dependencies via Homebrew using this command: arch -arm64 brew install pkg-config cairo pango jpeg giflib librsvg
4. In your root folder for the art engine project, install the project: npm install

The correct way is as follows：

1. Download and install the latest version of Node.js ， instead of the "LTS" （Long Term Support） version.
2. Install Homebrew.
3. Install dependencies via Homebrew using the following command ：arch -arm64 brew install pkg-config cairo pango jpeg giflib librsvg
4. In the root folder of your art engine project ，install the project：npm install

My solution

Combined with the above solution, The landlord did not upgrade the node version to the latest version, but used the LTS long-term support version of Node16.6， then Directly use Homebrew to execute the command brew install pkg-config cairo pango libpng jpeg giflib librsvg pixmaninstall

Wait for the above installation to complete,npm install or yarn install directly in the project

How to Solve Xcode 14 Pod Signature Error

Leave a reply

Background：

After pod install with Xcode 14, If there are bundle resource files in the library, an error will be reported during compilation, error: “igning for “xxxxx” requires a development team. Select a development team in the Signing & Capabilities editor.”

Solution：

Option 1：
Set the bundle identifier and team for the pod library that reported the error one by one.

Disadvantages: Our configuration will disappear after each execution of pod install, Need to manually set it again

Option 2：

Add the following configuration in Podfile, add and then re-pod update

post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings["DEVELOPMENT_TEAM"] = " Your Team ID &# 34;
         end
    end
  end
end

If you don’t want to set a specific team ID, try the following configuration：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle" 
      target.build_configurations.each do |config|
          config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
      end
    end
  end
end

[Solved] Android Compile and Package Error: Invalid keystore format

Leave a reply

Problem description

Running an old open source project, compiles the following error.

java.io.IOException: Invalid keystore format
Execution failed for task ':app:transformDexWithInstantRunDependenciesApkForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.signing.KeytoolException: Failed to read key AndroidDebugKey from store "C:\Users\a do\.android\debug.keystore": Invalide keystore format

Solution

According to the error message, there is a problem with the debug signature format.

We only need to open the c drive, in the current user’s directory, there is a .android directory, delete the debug.keystore inside.

If it prompts that the process is occupied, exit Android Studio first. Then delete it again.

Finally re-running the project, will automatically generate debug.keystore.
