After confirming that all files in the crack file have been copied to the installation file of MATLAB. The MATLAB shortcut cannot be started after clicking on the desktop. Delete the shortcut of the desktop and enter matlab.com under the bin directory file of the installation file Exe file to start.
When I want to create a new branch and switch to the new branch,
execute git checkout -b #233_change_something,
prompt error: switch ‘B’ requires a value
guess that the branch name is caused by the beginning of #,
so try to put quotation marks on the branch name
git checkout -b "#233_change_something"
Done!
Solution:
1. Start – run – enter CMD
2. Enter CD% windir%\system32 (enter system32 folder of windows installation directory)
3. Enter Regsvr32 msxml3.dll
4. All the above faults are solved

RuntimeError: CUDA error: device-side assert triggered
CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
The root cause is that the category label is not numbered from 0:
there are actually three categories of targets to be identified, so the total number of categories set is 3 Then set the corresponding relationship between category labels and categories as follows:
cls_dict = {'holes':1, 'marker':2, 'band':3}.
When numbering category labels, they are actually numbered from 0. For a total of 3 categories, the label numbers are 0, 1 and 2 respectively In other words, there is no label = = 3 category Therefore, the above CLS_Dict is adopted, which will cause the number of band class to overflow It should be corrected as follows:
cls_dict = {'holes':0, 'marker':1, 'band':2}
This kind of problem is generally a compiler configuration problem, the solution:
[Environment] windows
1.Click files, delete cache;
2.Click configure again, click the corresponding configuration
3.It is best to manually select X86, the VS version may not necessarily automatically select the computer type.
Problem description
I use the downloaded latex template to run, and the following error messages appear
resolvent
Switch the default compilation method, because Chinese appears in in the content
1. Click Options–>Configure TeXstudio...
2. Click build ->Default Compiler
Switch to xelatex
OK, solve the problem
Controller code:
Front end Ajax request code:
The status code 200 indicates that the request is successful, but the pop-up window (data returned by the server) cannot be received
Question tips:
SyntaxError:JSON. parse:unexpected character at line 1 column 1 of the JSON data
It is speculated that there was an error in parsing JSON data. The server wanted to use the string as JSON, but the format conversion failed
The reason is that I set the datatype in the Ajax request to “JSON”. JQuery will convert the string in the resp to JSON format according to this, but the conversion fails. Just comment out this line.
After formatting the code, single quotation marks will be changed into double quotation marks, and a comma will be added at the end. The semicolon at the end will lead to three kinds of errors:
1 Strings must use singlequote Quotes – double quotes
2 Extra semicolon semi — semicolon at the end
3 Error unexpected trailing comma comma Dangle — comma

1、 Problem description
After the Clickhouse is started, it can be accessed by itself. There is no problem, and it can also be accessed externally. However, check its error log and find that there are always errors
tail -f clickhouse-server/clickhouse-server.err.log
output:

...
It doesn’t stop, so it’s embarrassing.
2. Problem-solving
After probing, the Clickhouse server may have been started twice before. Therefore, check the status file directly according to the log directory
cat /var/lib/clickhouse/status
ps -ef | grep clickhouse-server
Delete the corresponding clickhouse-server
kill -9 $pid
systemctl start clickhouse-server
Then, check the error log again, and it’s OK
tail -f clickhouse-server/clickhouse-server.err.log

he -class attribute was wrong when I submitted the jar package.
Incorrect:
