failed to create cublas handle: CUBLAS_STATUS_ALLOC_FAILED

failed to create cublas handle: CUBLAS_STATUS_ALLOC_FAILED problem causes and solutions

when running a program using tensorflow’s gpu, this error is reported because the gpu has been occupied by another python script or because the gpu is repeatedly called by your own program. There are three types of situations in which individuals find this problem occurring, two of which are common, and one of which may be difficult to reach.
case 1: you already have a python program running on the gpu. If you run your own program, you will report this error.
solution: you can only turn off python programs that already use the gpu, and then run your own.
case 2: if the program is written by yourself, you may have the problem of repeatedly defining sessions, which is equivalent to calling the gpu again, so the error is reported.
solution: think about where another session has been defined, look for it yourself, and remove it.
case 3: the emergence of this situation, difficult to see, because we usually use a framework to deal with problems, such as tensorflow, but I also use the pytorch, problems arise in pytorch build datasets can’t occupy gpu calls when the gpu cause tensorflow
the solution: the problem in another framework will call the gpu, don’t let it use

JS Ajax request is successful, the response displays “failed to load response data”

# accident site

js ajax request succeeds, response shows “failed to load response data”

# reason

server returns too much data, resulting in data cannot be displayed;

# view the returned data by “open in new TAB “


note:
if this request is a Get request, that’s ok;
if the request is posted and has form data, then open in new TAB only opens the url of the request, without the form data information.

So,

, how do you do , open in new TAB , with formdata?The solution: use firefox firefox

tried many times and finally found the problem

because the table name HOMEpage_section cannot automatically become Entity’s table name. So I use @table (name=”HOMEpage_section”), but I feel in repository that the jpa resolution does not indicate that entity class name should be placed after the select

alias will solve the problem 

 @Query("select h from HomepageSection as h where parent_id = :parentid and del_flag = '0'")
    List<HomepageSection> findChildrenSectionsByParent(@Param("parentid") String parentid);


ExecutableNotFound: failed to execute [‘dot’, ‘-Tsvg’], make sure the Graphviz executables are on yo

problem occurs

has a problem drawing using the built-in features of xgboost 

ExecutableNotFound: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables are on your systems' PATH

looking for reasons

reason: graphviz itself was software, needed an extra download, and added its bin to the environment variable.

solution

download kit

Ubuntu can directly sudo apt install graphviz. If not, please go to graphviz’s official website to download or you can directly click this link to ubuntu to search graphviz package

environment dependencies refer to — several solutions for installing dependencies under Ubuntu

view file details (Windows, Linux common command)

after downloading, use dot-verison command to query the bin folder address,

at the white bar in the figure
Add the environment variable in Ubuntu

then add the environment variable, source /etc/profile to make it take effect. 

export PATH=$PATH:/usr/lib/x86_64-linux-gnu/graphviz

at this point the error is resolved and you can continue running the xgboost code.

[problem solving] Error:failed to get canonical path of /cow

this blog runs in Ubuntu18.04

problem description:
Error:failed to get canonical path of /cow

solution

use the recovery software boot-repair(after installing the Chinese system, look for “boot repair” in Dash) :

we need to use the system CD or U disk to enter the system, and then click “Try Ubuntu”

to install boot-repair, you need to add Ubuntu’s boot-repair PPA source and update the apt library. 

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update

Cannot add PPA if the error is reported… , can see: https://blog.csdn.net/weixin_44436677/article/details/107133371

below is the installation: 

sudo apt-get install -y boot-repair

use boot-repair to repair:

use boot-repair on the command line or click open in Dash, and then fix automatically in the software window or select advanced mode to set accordingly.

, wait a little, and restart.

Synergy Ubuntu 18 + win7 timed out or new client is unresponsive

how to install these two software, please move to this article:

https://blog.csdn.net/weixin_41995979/article/details/81990179

, that’s all I want to talk about, but what I want to talk about is the problem I had.

first, install synergy in Ubuntu. If you use the sudo apt-get install synergy command, you get 1.8.8. This can be checked by yourself after installation.

In the synergy interface, download. Deb version is not available in Ubuntu18. Therefore, it is recommended to use only

in Ubuntu18

sudo apt-get install synergy.

Ubuntu 16 can be downloaded. The deb version is self-installed.

the problem occurred when installing synergy in Ubuntu, which has been bothering me for a long time.

Ubuntu as the client side, win as the server side, the problem occurred: NOTE: new client is unresponsive

Ubuntu as the server and win as the client had the following problem: WARNING: failed to connect to server: Timed out

suggested that you check the setting of sunergy edit -, SSL that check off, should be able to solve.

Another problem with

is checking to see if the ports in the Settings are the same.

https://members.symless.com/forums/topic/4057-warning-failed-to-connect-to-server-timed-out/

and this is the way I saw it for this problem.

Compiling OBS studio on MAC and windos platforms

1. Under MAC xcode compiles obs-studio

1. Preparation

  • install brew
  • install other tools 
brew install ffmpeg x264 qt5
  • download code 
git clone --recursive https://github.com/obsproject/obs-studio.git

2. Generate xcode project 

1. cd obs-studio
2. mkdir -p builds/xcode
3. cd builds/xcode
4. CMAKE_PREFIX_PATH=/usr/local/Cellar/qt/5.11.1/ cmake ../../ -G Xcode

3. FAQ
set the working directory to {obs-studio build dir}build/rundir/Deubug(or Release)/bin, and set the method to Product-> Scheme-> Edit Scheme-> options-> working diectory.

Obs-studio

is compiled by visual studio under Windows 2017
1. Preparation

  • install cmake- GUI
  • download dependency
    • vs2017 dependency 
      https://obsproject.com/downloads/dependencies2017.zip

    • download QT 
      http://download.qt.io/archive/qt/5.11/5.11.1/qt-opensource-windows-x86-5.11.1.exe
    • download code 
      git clone --recursive https://github.com/obsproject/obs-studio.git //--recursive 会下载依赖包

2. Generate project

  • configure cmake and Add Entry 
    1. 添加 DepsPath 路径为下载vs2017依赖
2. 添加 QTDIR 为 msvc2017_64路径
3. 配置生成工程即可，然后指定目录打开sln文件编译即可。
  • start project set to ALL_BUILD can step debugging, do not set to obs project, that will lead to step debugging.
