Maskrcnn-benchmark Error: KeyError “Non-existent config key: MODEL.BACKBONE.OUT_CHANNELS“

When trying to extract visual features using VQA maskrcnn benchmark: files · master · vedanuj Goswami/VQA maskrcnn benchmark · gitlab,

After compiling maskrcnn benchmark according to the instructions of install, run

python script/extract_features.py ...

An error occurred:

KeyError "Non-existent config key: MODEL.BACKBONE.OUT_CHANNELS"

The problem is: instead of compiling maskrcnn benchmark, you can compile setup.py under VQA maskrcnn benchmark

PS: the author has made corresponding fine adjustments to the network structure and code. The structure in the original maskrcnn library does not correspond to config

kafka Error: Error while fetching metadata with correlation

Kafka report error

Server.log output:
error when handling request {topics = [indexing]} (Kafka. Server. Kafkaapis)
kafka.admin.adminoperationexception: replication factor: 1 larger than available brokers: 0

Run kafka-console-producer.sh output

WARN Error while fetching metadata with correlation id 0 : {enrichments=LEADER_ NOT_ AVAILABLE} (org.apache.kafka.clients.NetworkClient)

Run kafka-console-consumer.sh to swipe the screen

{metadata.broker.list=node01.bdp:6667, request.timeout.ms=30000, client.id=console-consumer-73407, security.protocol=PLAINTEXT}

The general solution on the Internet points to Kafka. Due to the wrong configuration of server.properties, it is unable to connect to zookeeper correctly. The root cause is that Kafka and zookeeper cannot communicate normally. Repeated restart of Kafka is still invalid

After restarting zookeeper, Kafka is normal

[Solved] Vsync Error: this error in animationcontroller in fluent

When using animation, it is usually written like this

  AnimationController _controller;
  Animation<double> _animation;
  Animation<Offset> _offsetAnimation;


  @override
  void initState() {
    super.initState();
    _controller =
    AnimationController(vsync: this, duration: Duration(seconds: 2))
      ..repeat(reverse: true);
    _animation = CurvedAnimation(parent: _controller, curve: Curves.easeIn);
    _offsetAnimation = Tween<Offset>(begin: Offset.zero, end: Offset(1.5, 0.0))
        .animate(_controller);
  }

However, Vsync: this in the animationcontroller will report an error (when Vsync exists, it will prevent off screen animation (when the UI of the animation is not on the current screen) from consuming unnecessary resources.)

Here, we need to add singletickerproviderstatemixin to the class definition, and use the statefulwidget class object as the value of this in Vsync. If you want to use a custom state object as Vsync, you can also use tickerproviderstatemixin

Writing method I

class DemoSizeTransition extends StatefulWidget {
  @override
  _DemoSizeTransitionState createState() => _DemoSizeTransitionState();
}

class _DemoSizeTransitionState extends State<DemoSizeTransition>
{
	with SingleTickerProviderStateMixin {
	.....//
	}
}

Writing method 2

import 'package:flutter/material.dart';
class DemoSizeTransition extends StatefulWidget {
  @override
  _DemoSizeTransitionState createState() => _DemoSizeTransitionState();
}

class _DemoSizeTransitionState extends State<DemoSizeTransition> with SingleTickerProviderStateMixin
{

  AnimationController _controller;
  Animation<double> _animation;
  Animation<Offset> _offsetAnimation;


  @override
  void initState() {
    super.initState();
    _controller =
    AnimationController(vsync: this, duration: Duration(seconds: 2))
      ..repeat(reverse: true);
    _animation = CurvedAnimation(parent: _controller, curve: Curves.easeIn);
    _offsetAnimation = Tween<Offset>(begin: Offset.zero, end: Offset(1.5, 0.0))
        .animate(_controller);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            FadeTransition(
              opacity: _animation,
              child: FlutterLogo(
                size: 150,
              ),
            ),
            SlideTransition(
              position: _offsetAnimation,
              child: FlutterLogo(
                size: 150,
              ),
            ),
          ],
        ),
      ),
    );
  }
}

It’s already running
java -jar ***.jar When the log comes out, pressing enter doesn’t actually end the process, so starting it again will report this error. After reinstalling jdk, it must not be running anymore, and it must be OK to start the project again.

ps -ef｜grep ***.jar to find the process number
Kill the process, then restart the project.

[Solved] Project Package Error: Javascript heap out of memory

Project package error:JavaScript heap out of memory
1、Modify package.json add –max_old_space_size=8192

"pro": "cross-env NODE_ENV=production node --max_old_space_size=8192 ./dist/server/server.js",

2. Execute increase memory limit


// global install
npm i -g increase-memory-limit

// into the project
increase-memory-limit

Error JavaScript heap out of memory means that the JavaScript heap is out of memory. JavaScript here refers to node. We all know that node is based on V8 engine. In general back-end development languages, there are no restrictions on the use of basic memory. However, when using memory through JavaScript in node, only part of the memory can be used (about 1.4 GB in 64 bit system and about 0.7 GB in 32-bit system). If the front-end project is too large, webpack compilation will occupy a lot of system resources. When it exceeds the default memory limit of V8 for node, memory leakage will occur.

MySQL (version 8.0) connection error: 1251 [How to Solve]

1. Error reporting

2. Reasons for error reporting

Because the encryption method of MySQL 8.0 is different from that of MySQL 5.0, an error will be reported when connecting

3. Solutions

You need to change the encryption method to connect successfully (follow the steps below).

1. Enter the DOS command and execute the following code to enter the database

mysql -uroot -proot //-u(database account) -p（database password）

2. Execute the following command

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password set during mysql installation';

You can also change the password with this command: change the password in the command to the new one

After completing the above two steps, there will be no error when connecting again.
