Problem Description
When using vscode to connect to a remote linux server ssh login suddenly fails to connect, showing Resolver error: Error
Personal solution:
1. Use other remote connection software to log in to the server, the blogger used Tabby
2. Use the command to find your own related processes: ps -ef | grep user_name
3. Find the pid of the process corresponding to .vscode, end the corresponding process: kill -9 $pid
4. vscode reconnect
Note:
For the time being, we do not know the reason for this frequent problem, but the above method can solve the connection failure problem.

Solution:
Compared with other similar services
it is found that
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
<!-- <version>2.2.7.RELEASE</version>-->
</dependency>
The version of openfeign is redundant and can be run after being commented out
During the actual operation of the recommendation system, the following errors occur when executing the featureengineering (Scala) file:
ERROR SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: System memory 259522560 must be at least 471859200
Solution:
1. Click Edit configurations
2 If your setting interface has the following red box, paste the following text directly
-Xms128m -Xms512m -XX:MaxPermSize=300m -ea
3. If not, click Modify options first, then add VM options, as shown in the figure below, and then complete the second step
this problem should be solved.
#Importing the openpyxl module
import openpyxl
## Create a workbook##
#1. Create a workbook
workbook=openpyxl.Workbook('.. /Excel_Data/data1.xlsx')
#2. create a sheet page (form)
sheet_name=workbook.create_sheet('sheet1')
#3. Write a data
sheet_name.cell(row=2,column=2,value="data written")
#4. Save
workbook.save('../Excel_Data/data1.xlsx')
Error in execution result:
AttributeError: ‘WriteOnlyWorksheet’ object has no attribute ‘cell’
reason:
The problem should be that the workbook cannot be written at the same time when it is created, so you can create and save the workbook first, and then open it, and the data can be written.
Crime scene
When using git to push the local code to the remote warehouse, the push fails (using the HTTP protocol). The error message is as follows:
$ git push
Enumerating objects: 3383, done.
Counting objects: 100% (3383/3383), done.

Compressing objects: 100% (1216/1216), done.

error: RPC failed; HTTP 413 curl 22 The requested URL returned error: 413
send-pack: unexpected disconnect while reading sideband packet
fatal: the remote end hung up unexpectedly
Everything up-to-date
Solution:
The data size of this push is 17m.
1. To solve the problem from the perspective of GIT, you can add the size of http.postBuffer
git config http.postBuffer 524288000
2. Because my Gitlab service is using Nginx as a domain proxy, it is possible that the client_max_body_size of nginx is limited and can be adjusted as follows.
client_max_body_size 1024m;
Background
In a timed task, the remote interface is called every hour for data synchronization. At first, the implementation method was to call the remote interface in a loop and pass in a single record each time, because each time we need to complete the operation of establishing a connection, data transfer, and disconnection, which is more expensive network and connection resources; later, after testing no problem, we changed to pass in a list for bulk operation after the loop is completed, and then the problem appeared.

Version information of openfeign :
Problem analysis
feign is configured as follows:
# feign
feign:
sentinel:
enabled: true
okhttp:
enabled: true
httpclient:
enabled: false
client:
config:
default:
connectTimeout: 10000
readTimeout: 10000
compression:
request:
enabled: true
response:
enabled: true
From the configuration, we can understand that the current configuration enables the request and response compression function. We know that when the compression is actually related to the size of the request body, if the requested data body itself is small, it can be transmitted directly without compression, which can save CPU resources for compression; there is a possible reason: compression is a threshold value, more than a certain threshold will be compressed. This can explain the previous question: why is it OK to transfer one piece of data at a time, but there is an error when transferring the list?
Solution:
Just turn compression off.
Note: Due to the change to bulk transfer, the business processing takes longer and errors like “Timed out…” may appear at the request initiation side. The configuration here changes the timeout of HTTP connection from 10s to 60s; when the data synchronization is finished, change it back.
Error reason:
The code uses GPU accelerated torch, but I downloaded the C + + version of torch. Use PIP list to find packages as follows:
Solution:
Uninstall torch and torchvision, and then use command pip install torch==1.7.0+cu110 torchvision==0.8.0+cu110 torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html to install it.
/**

//#define av_err2str(errnum) \
// av_make_error_string((char[AV_ERROR_MAX_STRING_SIZE]){0}, AV_ERROR_MAX_STRING_SIZE, errnum)
//Modify as the following:

{
static char str[AV_ERROR_MAX_STRING_SIZE];
memset(str, 0, sizeof(str));
return av_make_error_string(str, AV_ERROR_MAX_STRING_SIZE, errnum);
}
Modify libavutil/error.h:132 as the above.
Python parses a JSON string and directly calls JSON.Loads error:
NameError: name 'false' is not defined
Solution:
use Python’s raw strings, that is, add R'''before the JSON string, and then add '' '. For example:
>>> import json
>>> json_string = r'''{"created_at":"Thu Jul 10 20:02:00 +0000 2014","id":487325888950710272,"id_str":"487325888950710272","text":"\u5f81\u9678\u300c\u5de6\u8155\u306e\u7fa9\u624b\u306f\u30db\u30ed\u3060\u300d","source":"\u003ca href=\"http:\/\/twittbot.net\/\" rel=\"nofollow\"\u003etwittbot.net\u003c\/a\u003e","truncated":false,"in_reply_to_status_id":null,"in_reply_to_status_id_str":null,"in_reply_to_user_id":null,"in_reply_to_user_id_str":null,"in_reply_to_screen_name":null,"user":{"id":1429838018,"id_str":"1429838018","name":"\u3053\u3093\u306a\uff30\uff30\u306f\u5acc\u3060\u3002","screen_name":"iyada_pp","location":"\u516c\u5b89\u5c40\u306e\u3069\u3053\u304b\u3002","url":null,"description":"\u3010\u3053\u3093\u306aPSYCHO-PASS\u306f\u5acc\u3060\u306a\u3011\u3068\u3044\u3046\u304f\u3060\u3089\u306a\u3044\u5984\u60f3bot\u3067\u3059\u3002\u30ad\u30e3\u30e9\u5d29\u58ca\u304c\u6fc0\u3057\u3044\u306e\u3067\u3054\u6ce8\u610f\u304f\u3060\u3055\u3044\u3002","protected":false,"followers_count":99,"friends_count":98,"listed_count":5,"created_at":"Wed May 15 07:52:33 +0000 2013","favourites_count":0,"utc_offset":null,"time_zone":null,"geo_enabled":false,"verified":false,"statuses_count":12584,"lang":"ja","contributors_enabled":false,"is_translator":false,"is_translation_enabled":false,"profile_background_color":"C0DEED","profile_background_image_url":"http:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png","profile_background_image_url_https":"https:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png","profile_background_tile":false,"profile_image_url":"http:\/\/pbs.twimg.com\/profile_images\/3661872276\/ab7201283dac5dc1789bb6dfa9b6abe4_normal.jpeg","profile_image_url_https":"https:\/\/pbs.twimg.com\/profile_images\/3661872276\/ab7201283dac5dc1789bb6dfa9b6abe4_normal.jpeg","profile_link_color":"0084B4","profile_sidebar_border_color":"C0DEED","profile_sidebar_fill_color":"DDEEF6","profile_text_color":"333333","profile_use_background_image":true,"default_profile":true,"default_profile_image":false,"following":null,"follow_request_sent":null,"notifications":null},"geo":null,"coordinates":null,"place":null,"contributors":null,"retweet_count":0,"favorite_count":0,"entities":{"hashtags":[],"symbols":[],"urls":[],"user_mentions":[]},"favorited":false,"retweeted":false,"filter_level":"medium","lang":"ja"}'''

Solution:
Call the initialization package manually: go to sqlplus as administrator
1. sqlplus / as sysdba
2. check the current auto task belongs to the user already exists, if not then initialize the package
3. EXEC dbms_stats.init_package();
4. Confirm again
