Python Error: Process finished with exit code -1073740791 (0xC0000409)

Case 1 is also the case of more on-line): (graphics card) insufficient memory

At this time, we can adjust the memory in pycharm:
Press Shift + Ctrl + A to search for

where:
XMS in xms128m refers to the memory required for program startup, 128M is the size
xmx1011m in Xmx, Xmx refers to the memory required for program running, 1011m is the size
increase it. Of course, your hardware should be able to withstand this setting

[Solved] NoClassDefFoundError: jline/console/completer/ArgumentCompleter$ArgumentDelimiter

An error occurs when importing data using sqoop:

Exception in thread “main” java.lang.NoClassDefFoundError: jline/console/completer/ArgumentCompleter$ArgumentDelimiter

Caused by: java.lang.ClassNotFoundException: jline.console.completer.ArgumentCompleter$ArgumentDelimiter

Hadoop cannot find the jline package. Go to the Lib directory of hive to find jline.jar, put it in/share/Hadoop/yarn/Lib in Hadoop, and then execute it.

Echarts Partially introduced error: TypeError: Cannot read property ‘findAxisModel’ of undefined

When introducing dependencies locally in echarts, if there are dependencies that need to be used, an error will be reported if they are not introduced. For example, when using histogram + polar coordinates to display a ring chart, if Ploar is not introduced, an error will be reported in the title. At this time, just introduce this dependency:

require("echarts/lib/component/polar")

[Solved] Mac Cmake Complie openmp Error: fatal error: ‘omp.h‘ file not found

Mac OS 11.5.2, cmake default compiler appleclang 12.0.5

Make keeps reporting errors after compiling

fatal error: 'omp.h' file not found
#include<omp.h>

The reason is that a.cpp file introduces OpenMP, OMP.H

It can be compiled successfully through G + +, but the make default clang compilation in MAcc is not successful. In other words, it cannot be compiled through cmake on Mac

Try to resolve:

Adding before the project line of cmake has no effect

SET(CMAKE_C_COMPILER "/usr/bin/gcc")
SET(CMAKE_CXX_COMPILER "/usr/bin/g++")

On the command line, the export cxx = “usr/bin/G + +” variable also has no effect

Solution

Brew install libomp

brew install libomp

Change the path corresponding to OMP. H where. CPP introduces OMP. H

#include</usr/local/opt/libomp/include/omp.h>

Scala Flink Watermarker Error: Static Methods in interface require -target:jvm-1.8

explain

Gradle project + Scala 2.11 + java8 + Flink 1.12

Error code:

kafkaSource.assignTimestampsAndWatermarks(WatermarkStrategy
      .forBoundedOutOfOrderness[JSONObject](Duration.ofSeconds(10)))

Error message: static methods in interface require – target: jvm-1.8

From the perspective of error reporting, it is an error reported by Scala trying to call a static method in the java interface. However, JDK1.8 is used for compiling and packaging in the idea configuration

Modifying the following idea configuration is not valid:

So think about another breakthrough and add the following configuration to the build.gradle file to solve the problem.

project.tasks.compileScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]
project.tasks.compileTestScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]

Django project running service reported an error NameError: name ‘OS’ is not defined

Existing problems:
after Django creates a new project, when running the service command “Python manage. Py runserver”, an error is reported: NameError: name ‘OS’ is not defined

Solution:
find the setting.py file in the new project path and add “import OS” to it

Note: the method to judge whether the project is successfully created is if something similar to“ http://127.0.0.1:8000/ ”The project address, and “the install worked successfully! Integrations!” is displayed in the browser.

Using the TP framework, an error is reported sqlstate [08004] [1040] too many connections

Use
when MySQL inserts a large amount of data and needs to compare and duplicate          Db($table)-> where($where)-> find();

In this case, an error will be reported: sqlstate [08004] [1040] too many connections

This is mainly due to too many database connections

resolvent:

        Introduce DB class

                 use think\Db;

        The query statement is changed to:

                 Db::table($table)-> where($where)-> find();

That’s it
