Method 1: it may be due to heap memory problems
In setting — & gt; Build,Execution,Deployment–> Build process heap size (Mbytes) found in compiler: 700 changed to 1024 (as appropriate)
Method 2: it may be due to project coding
PS: I can compile it by changing it to GBK. The system default GBK format is invalid and needs to be manually changed to GBK
When downloading the dataset on the pytorch official website, an error is reported in sslcertverificationerror: [SSL: certificate_verify_failed]. The following is my solution.
Error reason: when opening HTTPS link with urllib, SSL certificate will be checked once. When the target website uses a self signed certificate, it will throw the error of urlib2.urlerror.
Solution: cancel certificate validation globally
Import SSL
SSL_ create_ default_ https_ context = ssl._ create_ unverified_ context

Today, after I used message queue, mailbox, ADC and multiple serial port threads at the same time, the system produced a series of errors.
The error contents are as follows:
After continuous attempts, I found a solution, which is recorded here.
Reduce the thread stack size of main thread and fishsh shell thread to 1024 (the value is for reference only).

Problem:
in the problem of handling Anaconda’s Navigator
involves upgrading the navigator
command: CONDA update Anaconda navigator
solution:
Add Anaconda Python free warehouse:
conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config –set show_ channel_ URLs yes
then upgrade again. (the first one already exists and will be prompted.)

Solution: install NVIDIA modprobe package:
sudo apt-get install nvidia-modprobeWhen NPM runs build, an error is reported: fatal error: ineffective mark compacts near heap limit allocation failed. Most of the answers are found on the Internet:
NPM install – G increase memory limit
enter the project directory and execute:
increase memory limit
this configuration is invalid. Then he said he wanted to put node_ Remove the double quotation marks in “XXX” under the modules folder (XXX forgot something). It’s also invalid
the last feasible solution:
open the CMD window and enter the command: setx node_ OPTIONS –max_ old_ space_ size=10240。 Then close the command window and rerun NPM run build. success!!!
When installing a debug package, the prompt is as follows
C:\Users\test>adb install "C:\Users\test\Downloads\test.apk"
Performing Streamed Install
adb: failed to install C:\Users\test\Downloads\test.apk: Failure [INSTALL_FAILED_TEST_ONLY: installPackageLI]
Solution:
adb install -t "C:\Users\test\Downloads\test.apk"
ADB install has lrtsdg six options
-L lock the application
– R replace the existing application, that is, force installation
– t allow the test package
– s to install the application on the SD card
– D allow it to be installed, that is, the installed version is lower than that on the mobile phone
– G grant all runtime permissions to the application

After checking the relevant information on the Internet, the reason for the error should be the problem of font recognition by uniapp,
that is, the problem caused by the following fonts:
src:url(https://img.yzcdn.cn/vant/vant-icon-96970a.woff2) format("woff2"),url(https://img.yzcdn.cn/vant/vant-icon-96970a.woff) format("woff"), url(https://img.yzcdn.cn/vant/vant-icon-96970a.ttf) format("truetype")}
These fonts are in the wxcomponents/vant/dist/icon/index.wxss file
in the wxcomponents/vant/dist/icon/index.wxss file, Ctrl + F, enter the icon number 96970a in the error report (my error report icon number here is 96970a, you can search according to your own error report icon number), then add a space before the second and third URLs respectively, and finally save the current file. (key to problem solving)
Rerun the compiled project or release the packaged project and it will be solved successfully
