dtype=np.int error: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`.

Leave a reply

There is a line of code c = np.fromfile(“b.dat”, dtype=np.int, sep=”,”) when running Error，The content is as follows：

DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20 .0-notes.html#deprecations
c = np.fromfile(“b.dat”, dtype=np.int, sep=”,”)

Reason: numpy1.20 has deprecated np.int, checked my version

The numpy version has reached 1.23.2

Solution: Change to np.int16/np.int32 directly to specific bytes or change to np.int_

Run again, problem-solved!

[Solved] JNI Error: Fatal signal 11 (SIGSEGV)

2022-09-14 09:19:01.092 3562-3580/com.derry.opengl A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x24 in tid 3580 (GLThread 103)

I often encounter this kind of error report, making me very bummed.

I tried a solution (rooted phone or emulator, otherwise the error log file can not be found): 1.

1. find the file where the logs are located: data/tombstones

2. Find the file with this latest date

3. save the file to the desktop (I did not encounter problems with permissions using the emulator, so I can export directly) If you encounter insufficient permissions, you need to use su superuser permissions (chmod 777 xxxxx)

4. open the log file: there are error logs inside (this point is not enough permissions for me) specific analysis of the problem, this point is mainly to explain how to view this log file

How to Solve linq Statement IsNullOrWhiteSpace Error

Leave a reply

Using the IsNullOrWhiteSpace method in a linq statement will report an error，

Error message: System.NotSupportedException: ‘LINQ to Entities does not recognize the method ‘Boolean lsNullOrWhiteSpace(System.String)’ method, and this method cannot be translated into a store expression.’

You can use the method below to solve:

You can also use IsNullOrEmpty, IsNullOrEmpty method does not report an error, normal operation

The following figure is the analysis of these two methods:

Can’t resolve ‘ansi-html-community’ & Cannot find module ‘is-docker (vuex-persistedstate Installed)

Leave a reply

When the following error occurs in the console，it means that the plug-in is installed incorrectly

Can’t resolve ‘ansi-html-community’

Cannot find module ‘is-docker

Don’t use npm install

npm i vuex-persistedstate

But the environment you use is yarn, so you need to use yarn to install the plugin

yarn add vuex-persistedstate

Then the problem can be solved smoothly

tuxedo Compile Background Common Error [How to Fix]

Leave a reply

Error 1: When compiling the service written by Proc, the header file cannot be found

Solution：

Check whether the language configurations such as nls under the .bash_profile file are the same as the oracle user’s .bash_profile.

Error 6: When compiling background source files, prompt buildserver related errors

Solution：

Check whether the configuration and order related to tuxedo under the .bash_profile file are correct (Compare with the actual path).

Error 7: Compile background source files, prompt “You do not have a valid SDK license”

Solution：

Maybe the license of tuxedo is incorrect. Check whether the lic.txt under /home/tuxedo/Tuxedo 8.1/bealic has been overwritten, or check whether the TYPE= SDK in lic is correct, and the value of type is SDK.

[Solved] Flutter Error: fluwx:compileDebugKotlin

Leave a reply

Flutter reports an error fluwx:compileDebugKotlin

Cause Analysis

The reason for this exception found on the Internet is basically that the kotlin version does not conform to the cause, Maybe the kotlin version will also cause this error.
But my error is not due to the kotlin version problem, but due to the conflict of the component cache version pulled down by the pub command, as shown below:
insert picture description here
fluwx-3.9.1 and 3.9.2, delete and yml file Inconsistent versions resolve this exception.

Summary

Component name: There may be two reasons for the exception of compileDebugKotlin:
1. The kotlin version often said on the Internet does not conform to
2. There are different versions of the components in the pub cache and they conflict

TS Failed to Use hasOwnProperty Method [How to Fix]

Leave a reply

Determine whether the obj object contains the children attribute, but the following error occurs

Do not access Object.prototype method ‘hasOwnProperty’ from target object.

Cannot directly access methods on Object prototype

Reason：

It is not safe to call hasOwnProperty directly on the result object，If the obj object itself has the hasOwnProperty property，there will be some unexpected problems when calling it. If someone with intentions takes advantage of ，set the property in obj to malicious code， will cause some security issues.

Workaround：

Use call to change the call point

const hasChild = Object.prototype.hasOwnProperty.call(obj, 'children');
