Steps
Step 1
Check if the following installation packages are installed, if they are missing, please install them.
| libcgroup-0.41-8.el7.x86_64.rpm libcgroup-tools-0.41-8.el7.x86_64.rpm |
Step 2
Set up the cgroup service to start on boot after installation.
| systemctl enable cgconfig.service |
Step 3
Start the cgconfig service.
| systemctl start cgconfig.service |
Error description
error: unknown type name ‘bool’; did you mean ‘_Bool’?
Cause of error
Unknown type name: ‘bool’, because the boolean type is not defined in the C standard (C89), so it will report an error. C99 provides a header file that defines bool, true for 1 and false for 0. Just import stdbool.h and you can manipulate boolean types very easily.
Solution:
//add the header file
#include <stdbool.h>This is the most depressing thing I encountered in learning ArcGIS pro. The error is reported as follows. This is the most depressing thing I encountered in learning ArcGIS pro. The error is reported as follows
This error occurs when using jupyter notbook because “Due to repeated uninstallation of anaconda or too many python versions installed, the path of the notbook kernel startup is confused and needs to be manually adjusted by yourself”. The solution is simple, open Python Prompt and type python -m ipykernel install -user, reinstall the kernel and restart.
I changed the version, I reinstalled Arcgis Pro2.5, and the above problem was solved wonderfully
1. Error reporting:
Use the journalctl – xefu kubelet command to view the kubelet log. The following errors are found:
cannot find network namespace for the terminated container
2. Solution:
# docker system prune
# systemctl restart kubelet
Instructions for using docker system:
# docker system -h
Flag shorthand -h has been deprecated, please use –help
Usage: docker system COMMAND
Manage Docker
Commands:
df Show docker disk usage
Check the usage of docker space.
events Get real time events from the server
View live events.
info Display system-wide information
View system information.
prune Remove unused data
Docker cleans the stopped container, and there is no network, image and cache used by the container.
Publisher confirms = true reports an error
When rabbitmq connectionfactory is defined in the configuration file, publisher-confirm will report error
Solution: the new version of confirm-type=”CORRELATED” replaces the old version of publisher-confirm=“true”
There are two solutions to solve Error: Could not determine java version from '11.0.8'.
Method 1: downgrade Android Studio and use the historical version of Android Studio environment;
Method 2: upgrade Gradle version;
1. Error reporting information
Open an old project and report the following error:
Could not determine java version from '11.0.8'.
The project uses Gradle version which is incompatible with Studio running on Java 10 or newer.
See details at https://github.com/gradle/gradle/issues/8431
Possible solution:
- Upgrade Gradle wrapper to 4.8.1 version and re-import the project
Select the “menu bar/file/Project Structure” option,
Check that the Android Gradle plug-in version of the Android project is 3.2.0 and the Gradle version is 4.6. This is the version used a few years ago. At present, the project cannot be compiled using the latest Android studio;
2. Solution
Select the menu bar/file/project structure option,
In the pop-up project structure dialog box, update the Android gradle plug-in version to 4.2.1 and the gradle plug-in version to 6.7.1;
DevTools failed to load SourceMap: Could not load content
What it means here is that the dev tool failed to load the source mapping: it couldn’t load the content. The focus is on the part after the for.
The hint I encountered was something like this
DevTools failed to load SourceMap: Could not load content for chrome extension://ncennffkjdiamlpmcbajkmaiiiddgioo/js/xl-content.js.map
That is, the part of the chrome extension tool, the mapping failed to load successfully.
After inquiry, the latter link is caused by the opening of the Xunlei extension tool in chrome, but it does not affect normal operation, you can also consider disabling the tool in the extension program
After installing opencv with PIP3, an error is reported when importing CV2 through Python 3, as follows:
from .cv2 import *
ImportError: numpy.core.multiarray failed to import
Beacuse the version of NumPy library is too low or too high, which is not suitable for the newly installed opencv version
if we use pip to install the latest version of OpenCV, that is, the installation command:
pip3 install opencv-python
pip3 install opencv_contrib-python
It means that the numpy version is too low, so we should install the latest version:
Command: pip3 install -U numpy
After installation, you can import OpenCV
Maven released jar package
error: failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy
Cause: missing configuration
Solution: Add configuration to the Maven configuration file settings.xml
Open the file settings.xml under the directory …apache-maven-3.2.3-binapache-maven-3.2.3conf and add the configuration.

DLL load failed while importing rdBaseThe rdkit package may be damaged, so you can reinstall the rdkit. The installation code is as follows
conda install -c rdkit rdkitHowever, it is recommended to install deepchem in a separate virtual environment, it will affect many of the previously installed packages, such as numpy and so on
