Altium designer 18: failed to export

Problem description:

use AD18 in PCB with export has been unable to export the 3 d step, prompt unable to export.

Cause of the problem:
It is due to 3D packaging model error, here is the terminal 3D error caused

Solution:
Simple solution to
select export PCB selected to export the selected 3 d models,

although can’t see all of the components but can you give export board shape and hole to thoroughly solve the
click on the 3 d assembly model to check 3 d properties, 3 d model will be deleted only keep screen printing

Remember a mybatis error org.apache.ibatis . session.defaults.DefaultSqlSession

Today, MyBatis was used to insert a hop record into the database, and the error was reported as follows:
SqlSession [org. Apache. Ibatis. Session. Defaults. DefaultSqlSession @ 74794994] was not registered for synchronization because synchronization is not active
The error is due to the fact that one of my fields is NULL, but the database design, this field cannot be NULL, so the error is to change the input field not NULL, to solve the error.
Welcome to pay attention to my public number, learn together, exchange.

 

[solved] closingontransa ctionalSqlSessionorg.apache.ibatis . session.defaults.DefaultSqlSession @20] No information after that.

Today in learning to follow the teacher learning Mybatis – plus technology found god in the use of the test class testing to add and delete operation, display Closing non transactional SqlSession [org. Apache. Ibatis. Session. Defaults. DefaultSqlSession @ 656922 a0] after no information feedback, no results after searching for some information.

The solution
Eventually find the main class does not start: @ MapperScan (com. Kuang. "mapper")
pay attention to the point, we need to start class up to scan our mapper package of all interface

to add @ MapperScan (" com. Kuang. Mapper ") scans we mapper under UserMapper interface inheritance parent class BaseMapper< User> . In order to identify all methods in the parent class.

import org.mybatis.spring.annotation.MapperScan;
@MapperScan("com.kuang.mapper")

Then test the class again and find that the data is present and the information is fed back.

Build your own resnet18 network and load torch vision’s own weight 

import torch
import torchvision
import cv2 as cv
from utils.utils import letter_box
from model.backbone import ResNet18


model1 = ResNet18(1)
model2 = torchvision.models.resnet18(progress=False)
fc = model2.fc
model2.fc = torch.nn.Linear(512, 1)
# print(model)
model_dict1 = model1.state_dict()
model_dict2 = torch.load('resnet18.pth')
model_list1 = list(model_dict1.keys())
model_list2 = list(model_dict2.keys())
len1 = len(model_list1)
len2 = len(model_list2)
minlen = min(len1, len2)
for n in range(minlen):
    if model_dict1[model_list1[n]].shape != model_dict2[model_list2[n]].shape:
        continue
    model_dict1[model_list1[n]] = model_dict2[model_list2[n]]

model1.load_state_dict(model_dict1)
missing, unspected = model2.load_state_dict(model_dict2)
image = cv.imread('zhn1.jpg')
image = letter_box(image, 224)
image = image[:, :, ::-1].transpose(2, 0, 1)
print('Network loading complete.')
model1.eval()
model2.eval()
with torch.no_grad():
    image = torch.tensor(image/256, dtype=torch.float32).unsqueeze(0)
    predict1 = model1(image)
    predict2 = model2(image)
print('finished')
# torch.save(model.state_dict(), 'resnet18.pth')

Property ‘style’ does not exist on type ‘element‘

Property ‘style’ does not exist on type ‘element’ property does not exist on type ‘element’
Reason: This is caused by TypeScript type checking, which requires a type assertion in front of the querySelector method.

let frameContainObj = document.getElementById("model_view_container")
let iframeObj= <HTMLElement>frameContainObj.querySelector("#modelView");
iframeObj.style.height = document.documentElement.clientHeight* 0.65 + "px";

Extensions: When using QuerySelectorAll, the following scenario can be used:

let block = document.querySelectorAll(".block") as NodeListOf<HTMLElement>;

Tells the TypeScript compiler to pass this code by setting assertions

Modify the custom keyboard shortcut of visual studio code

Many IDEs, such as Eclipse and Visual Studio Code’s Auto Completion Intellisense shortcut key, use Ctrl + Space, which conflicts with Chinese developers’ cases of switching Chinese and English input methods, which is very annoying.
How to toggle IntelliSense shortcut key definitions in Visual Studio Code:
File-> Preferences-> Settings Enter the Settings menu:

Go to the Trigger Suggest’s original button Settings: Ctrl + Space

I changed it to a different combination: Ctrl + L

Now press Ctrl + L to trigger the autocomplete function, which will no longer interfere with the Chinese/English input method.

Successfully solved the problem that visual studio code could not go to the definition, and there was no mouse prompt

Visual Studio Code does not prompt the definition I can not solve

Today suddenly found my vscode without prompt, not even to the definition of function, it was like a TXT text reader, then I have been to install a plug-in, even put vscode uninstall reinstall is useless, I finally in a prompt window to set the configuration file that I have a set of changes over the

the picture intelliSenseEngine was transformed to Disable, lead to code doesn’t provide context awareness, Then change to Default according to the selection prompt

Encapsulation of Ajax JSON / fromdata request in native JS

ajaxPost

function ajaxPost(url,json,cb){
	var xhr = new XMLHttpRequest();
	xhr.open('post',url);
	xhr.setRequestHeader("content-type","application/json");
	xhr.send(JSON.stringify(json));
	xhr.onload = function(){
		cb(JSON.parse(xhr.responseText));
	}
}

Posting pictures

function ajaxPic(formObj,url,cb){
	var formData = new FormData(formObj);
	console.log(formData);
	var xhr = new XMLHttpRequest();
	xhr.open('post',url);
	xhr.send(formData);
	xhr.onload = function(formData){
		cb(JSON.parse(xhr.responseText));

java.lang.IllegalArgumentException : URI is not absolute error

Problem phenomena:
After the framework uses SSO (Spring Security OAuth2.0), the Token has been produced. When using the Token to call the interface in Postman, the console appears URI is not absolute error
Analysis of the problem:
Use breakpoints to discover that the URI received in createRequest is empty when the request is created. The first reaction is that there is a problem with the configuration. After checking the YML file, no problem is found

 
In this file, see

@Bean
protected JwtAccessTokenConverter jwtTokenConverter() {
   JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
   converter.setSigningKey("test");
   return converter;
}

After the new step is commented out, add a symmetric key to the corresponding resource service, and use the PostMan call to succeed magically.
Actual reasons for follow-up research…

java.lang.IllegalArgumentException : URI scheme is not “file” error resolution

Java. Lang. IllegalArgumentException: URI scheme is not “file” error

The code in
Map side setup is as follows

        URI[] uris = context.getCacheFiles();
        File file = new File(uris[0]);
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));

Code cached in the Driver phase

job.addCacheFile(new URI("/MR/job/input/com.txt"));

After thinking about it and looking for some forums on the Internet, I thought it might be what I wanted to do, but I could not do it with File, so I should do it with Stream.
file f = new file (UI)
le f = new file (UI)
file f = new file (UI)
file f = new file (UI); The file protocol
is now the URL(” http://… “) ) it is impossible to document
so will some changes have been made the setup phase of the code

        URI[] cacheFiles = context.getCacheFiles();
        FileSystem fileSystem = FileSystem.get(cacheFiles[0], context.getConfiguration());
        FSDataInputStream inputStream = fileSystem.open(new Path(cacheFiles[0]));
        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));

Found that after the change was really good
