Cause analysis:

I remember converting the suffixes of properties files to YML files directly according to the video, and then the Chinese comments on the page became garbled, so I naturally converted them to GBK format, and then the above error was reported

The first possibility is that there is a problem with the encoding format of your application.yml file, which is changed to UTF-8
the second possibility is that your application.yml file is generated by directly changing the suffix of other types of files to YML. At this time, you need to copy all the contents in application.yml, delete them, and then create a new application.yml file, Copy the copied content into it and then run the project, and no error will be reported.

Solution:

Find file coding in the setting of idea

Convert GBK to UTF-8, and then rewrite the Chinese annotation to run normally

I’m not a professional, and my English is not good. I can’t understand what’s wrong. I have seen that there is no missing value in the date column of the file, and there is no date that does not conform to the format… This is very strange, welcome to leave a message, thanks in advance!

Solution

When converting, add a parameter errors ='coerce '.

reader = pd.read_csv(f'new_files/2020-12-22-5-10.csv', usecols=['passCarTime'],dtype={'passCarTime':'string'})
reader.passCarTime = pd.to_datetime(reader.passCarTime,errors='coerce') 
reader.passCarTime.head()

When installing pyaudio, an error is reported: failed error: portaudio. H: there is no such file or directory

When installing pyaudio, an error is reported: failed error: portaudio. H: there is no such file or directory

 
The operation of pyaudio depends on the portaudio library. You should first install a portaudio library

Portaudio installation steps:

A) Download PortAudio Library http://portaudio.com/download.html , select the latest tgz, upload it to Linux or termux and place it where you want to install it. Termux: I put it in/data/data/com.termux/files/usr/share, and CD it to this directory

B) tar – zxvf file name         Unzip the downloaded files without tar, such as apt get install tar

C) enter the decompressed portaudio file and execute the following commands in turn:

　　　　./configure

(configure command)

This step is generally used to generate makefile to prepare for the next step of compilation. You can control the installation by adding parameters after configure. For example, the code:./configure – prefix =/usr means to install the software under/usr, and the executable file will be installed in/usr/bin (instead of the default/usr/local/bin), The resource file will be installed in/usr/share (instead of the default/usr/local/share). At the same time, some software configuration files can be set by specifying the – sys config = parameter. Some software can also add – with, – enable, – without, – disable and other parameters to control the compilation. You can view the detailed instructions and help by allowing./configure – help.

In termux, this step is set to

./configure –prefix=/data/data/com.termux/files/usr

）

　　　　make     compile

　　　　make install     Installation

4. Install pyaudio library, PIP3 install pyaudio

Appium step pit summary — solution

1. There are appium command version and appium desktop version in the computer, After opening appium desktop version, the script will run with an error:
selenium.common.exceptions.webdriverexception: Message: an unknown server-side error occurred while processing the command. Original error: cannot start the ‘com. XXXX’ application.
main meaning: an unknown server-side error occurred while processing the command

Check:
I found that the command line version (1.20.2) is inconsistent with the desktop version (1.14.1), appium – V, view version

Solution:
close the desktop version, enter appium in the CMD to execute the command line version, execute the script, and it can run successfully
solution 2: upgrade the desktop appium version or reduce the appium command line version

Error: not found; no service started

Sometimes it’s a headache to report an error. If you have a problem with your own code, you can still solve it. However, if there is a problem with the as tool, it’s embarrassing!
I’ve heard that as2.3 has its own bug before, but I haven’t encountered it. Fortunately, I did today! All kinds of search information, over the wall!
The error is as follows:

Starting service: Intent 
{ act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] 
cmp=com.xxx.xxx.constrain/com.android.tools.fd.runtime.InstantRunService }
Error: Not found; no service started.

Solution:
first, simply and crudely re install as2.3 (I use version 2.3)
Second, upgrade as in the case of upgrade. At present, my as is upgraded from 2.3 to 2.3.1
and above, and all the problems can be solved

Attributeerror: object has no attribute

Error report: in the front-end test, the interface sends a put request, the error report occurs on the interface, the request cannot respond, and the server status code is 500.

Error analysis: semantically, “the object does not have a XXX attribute.”.

Look up most of the information, most of the problems with Python. The front end of this project uses react, and the back end uses the djongo framework of Python.

The main reason for asking the back-end colleagues is that the data type of the parameters passed by the front-end is incorrect. The back end needs a string “true”, but the front end passes a Boolean “true”, which causes the above problem.

In case of such a problem, the error code returned by the server is 500. For such a problem, usually ask the back-end colleagues to check the log for common analysis.

Solution of running error reporting attributeerror: ‘rectangle’ object has no property ‘normalized’

Have a problem

When running the code, the following error prompt appears:

AttributeError:'Rectangle' object has no property 'normed'

resolvent

The reason is that the library has been updated and there is no such attribute. Delete the normal in the code (no error, but it seems that it can’t be drawn)

Replace the normal attribute in the code with density , and add an attribute stacked = true .

Thank you for your comments.

insufficient permission for adding an object to repository database 

Because the. Git directory of the project has the permission of root,

The solution is to switch to the root super administrator and modify the user of the file as the current computer user
