The solution to this problem is to reduce the version of NVIDIA tensorrt [2021-8-27]
reference link: https://github.com/NVIDIA-AI-IOT/torch2trt/issues/557

pip install nvidia-tensorrt==7.2.* --index-url https://pypi.ngc.nvidia.com

Finally, with the following command, the model conversion was successful. It took 10 minutes, which was outrageous

=====================================================

I encountered this problem in a project where the front-end and back-end are separated
The front-end input data is “payTime”: “NULL”,
“tradeNum”: “null”,
“updateTime”: “2021-08-17 16:39:50”,

The console reports this error
====================================================
The reason for the error: the type of payTime is not correct, this capital NULL is the data I copied from the database and put in every too much attention, it should be consistent with the following null.

 

[Solved] Android Error: AAPT: error: unescaped apostrophe in string；Multiple substitutions specified in non-positi

I. AAPT: error: unescaped apostrophe in string </ font>

Cause analysis of error reporting

When doing the internationalization multilingual function, I defined some strings in the arrays.xml file as follows

<item>My name's Lisa</item>

The error report is translated as the apostrophe
that is not replaced by the string. Therefore, I thought that the error report may be caused by ', so I replaced the above code with the following code to solve the error report.

<item>My name&quot;s Lisa</item>

Error reporting solution

apostrophe ' available & amp; quot； replacement, such as: <item> My name& quot; s Lisa you can use double quotation marks to enclose string resources, such as: <item>" My name's Lisa" escape characters can be used before apostrophe ', such as: <item> My name\'s Lisa

II. Multiple substitutions specified in non positive format

Cause analysis of error reporting

First, I defined some strings in the string. XML file

<string name = "upgrade_time"> Driver board: %s\t\t signal version.%s</string>

Error reporting translates to multiple substitutions specified in a non location format. The error reporting prompt mentions setting formatted = "false" , so I change the above code to the following one, so I won’t run error reporting.

<string name = "upgrade_time" formatted="false"> Driver board: %s\t\t signal version.%s</string>

Error resolution
After reviewing some blog posts and trying it out myself, there are these ways to fix the above error.
Add formatted="false" attribute in the string with %% to indicate a %
Third, some common HTML special character encoding
In the Android xml file, involving some special characters may be reported in the display of the error, you need to use HTML special characters to convert.

Special symbols HTML encoding

Error while loading error while loading shared libraries [How to Solve]

Error while loading error while loading shared libraries solution

If it’s missing, find it and put it back

Distribution: archlinux
as stated in the title, take the yaourt encountered before writing this article as an example:

➜  ~ yaourt -Ss uswsusp
yaourt: error while loading shared libraries: libalpm.so.12

After looking at the in the system, I found that libalpm. So has been upgraded to 13 

➜  ~ ls -l /usr/lib/libalpm.so*
lrwxrwxrwx 1 root root     13 Jul 16 03:26 /usr/lib/libalpm.so -> libalpm.so.13
lrwxrwxrwx 1 root root     17 Jul 16 03:26 /usr/lib/libalpm.so.13 -> libalpm.so.13.0.0
-rwxr-xr-x 1 root root 243608 Jul 16 03:26 /usr/lib/libalpm.so.13.0.0

Well, the problem is very simple. The library has been upgraded, but the dependent software developers have not upgraded.

Next, only three steps are required:
confirm the software from libalpm. So and download the old version (which may contain 12 generally open the package. You can directly find the corresponding link library and copy it to under /usr/Lib My detailed steps:
the search discovery may be in the Pacman package

➜  ~ pacman -Ss libalpm
core/pacman 6.0.0-5 (base-devel) [installed]
    A library-based package manager with dependency support
extra/pyalpm 0.10.6-1
    Python 3 bindings for libalpm
(..... Other insignificant packages)

To download the old software package of archlinux, you need to find it in arch archive.

In the /packages/P/Pacman/ directory, I tried to download the previous version of the current version (v6.0.0), pacman-5.2.2-4-x86_ 64.pkg.tar.zst

Open it directly and find libalpm. So. 12

finally, copy the extracted libalpm. So. * to /usr/lib （ Be careful not to copy the one without version suffix ( libalpm. So )

error: initializer element is not constant [How to Solve]

1. Background

C language compilation error: error: initializer element is not constant. The error code is as follows:

    char *info = (char *)malloc(len);
    static char *info_t = info;

The above error is caused by trying to initialize a static variable with the memory pointer allocated by malloc.

2. Error reason

Static variable is a global variable. The value of the global variable cannot be determined at compile time, but at run time (compilation principle). Therefore, the global variable cannot be initialized directly with the return value of malloc at the time of declaration. Replace with the following:

    char *info = (char *)malloc(len);
    static char *info_t; 
    info_t = info;

Compilation passed.

SSL error when connecting to the Jack server. Try 'jack-diagnose'

The problem remains the same, so the focus is still on SSL communication:
finally, it is solved by the following methods:

1. Edit/etc/java-8-openjdk/security/java.security 
#
# Algorithm restrictions for Secure Socket Layer/Transport Layer Security
# (SSL/TLS) processing
#
# In some environments, certain algorithms or key lengths may be undesirable
# when using SSL/TLS.  This section describes the mechanism for disabling
# algorithms during SSL/TLS security parameters negotiation, including
# protocol version negotiation, cipher suites selection, peer authentication
# and key exchange mechanisms.
#
# Disabled algorithms will not be negotiated for SSL/TLS connections, even
# if they are enabled explicitly in an application.
#
# For PKI-based peer authentication and key exchange mechanisms, this list
# of disabled algorithms will also be checked during certification path
# building and validation, including algorithms used in certificates, as
# well as revocation information such as CRLs and signed OCSP Responses.
# This is in addition to the jdk.certpath.disabledAlgorithms property above.
#
# See the specification of "jdk.certpath.disabledAlgorithms" for the
# syntax of the disabled algorithm string.
#
# Note: The algorithm restrictions do not apply to trust anchors or
# self-signed certificates.
#
# Note: This property is currently used by the JDK Reference implementation.
# It is not guaranteed to be examined and used by other implementations.
#
# Example:
#   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves




2. Find the line of TLSv1, delete TLSv1, TLSv1.1, and save it.

3. switch to the Android compiled source project directory: prebuilts/sdk/tools/

4. Run.

./jack-admin kill-server 

./jack-admin start-server

Error querying database.Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource.

Record the problems encountered in the learning process of Java mybatis framework

1. An exception occurred while building the first mybatis project:

Exception in thread "main" org.apache.ibatis.exceptions.PersistenceException: 

Error querying database. Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource. 
Cause: java.lang.ClassNotFoundException: Cannot find class: com.mysql.cj.jdbc.Driver

Solution: the MySQL connector Java driver version is used incorrectly
I use MySQL version 8.0.22

import the driver of version 5.1.23, and the dependency declared in pom.xml file is

<dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.23</version>
    </dependency>

The two versions do not correspond, so the driver error cannot be found.
the solution is to download the driver of version relative to, that is, the driver of version 8.0.22. The official website address is version 8.0.22
and then change the dependency in the POM file to:

<!--MySQL-->
<dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>8.0.22</version>
    </dependency>

Another point is that the POM file should include not only driver dependencies, but also mybatis dependencies

<!--mybatis-->
<dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.5</version>
    </dependency>
