The solution to this problem eventually returns to the problem of version synchronization
The versions at the two arrows should be consistent.

[Solved] Odoo Cannot log in error after the Database is Recovered
Many odoo users have encountered the problem that the backed up database cannot be restored
You can self-check in the following ways
1. Is the odoo version correct? Different versions of odoo cannot be restored directly, for example, odoo13 cannot be restored directly to odoo15
2. Whether the database version is correct, postgres may have problems when it is backward compatible. It is recommended to migrate to the same version.
3. Whether the code is migrated correctly, inconsistent codes on both sides will also cause an error, which is common in the conf file without specifying the code location.
If you confirm that the above content is correct, you can try the following methods
1. Add -d database name -i base when starting odoo through the command line, this method is to select the database to force the update of the base module; because all odoo modules are dependent on this, the mandatory update will be all the modules installed in the database after the base Will be upgraded.
2. Enter postgres, enter the following command
su postgres; # Switch postgres users
psql; # Enter the postgres command line
\c; database name # specify database instance
DELETE FROM ir_attachment WHERE url LIKE '/web/content/%'; # Delete the front-end files cached in the data tableGenerally, most problems can be solved through the above two steps.

Import CV2 & Numpy report red Warning and Error [How to Solve]
Usually the red report after import is because there is no module, use pip install cv2 to download the module, it will appear:
Could not find a version that satisfies the requirement cv2 (from versions: )
No matching distribution found for cv2
You are using pip version 18.1, however version 19.0.2 is available.
You should consider upgrading via the ‘python -m pip install –upgrade pip’ command.
At this point you need to type python -m pip install –upgrade pip
When the installation is complete, run this line “pip install opencv-python”, this line is to install the cv2 module, wait until the download is complete
To install the numpy module, you only need to pip install numpy
The summary is as follows:
python -m pip install --upgrade pip
pip install opencv-python

How to Solve Error: Error no module “Tkinter”
Error no module “Tkinter”
Principle:
Import Tkinter in python3 import Tkinter in python2
It’s just the difference in the case of the beginning in the python version.
Therefore, we can modify the startup version of Python. One is to directly modify the system version, and the other is to modify the specified version of Python file
here we mainly talk about how to modify the specified version of Python files.
Add the following two lines at the beginning of the .Py file:
#! /usr/bin/python2.7
# -*- coding utf-8 -*-
How to Solve QGIS installation paddy GPU error
QGIS installation paddy GPU error
Error content
Use the following code to check whether the paddle GPU is installed successfully
import paddle
paddle.utils.run_check()
Get the following error reports
RuntimeError: (PreconditionNotMet) The third-party dynamic library (cublas64_102.dll;cublas64_10.dll) that Paddle depends on is not configured correctly. (error code is 126)
Suggestions:
1. Check if the third-party dynamic library (e.g. CUDA, CUDNN) is installed correctly and its version is matched with paddlepaddle you installed.
2. Configure third-party dynamic library environment variables as follows:
- Linux: set LD_LIBRARY_PATH by `export LD_LIBRARY_PATH=...`
- Windows: set PATH by `set PATH=XXX; (at C:\home\workspace\Paddle_release\paddle\fluid\platform\dynload\dynamic_loader.cc:265)
It is found that other CONDA environments can be used normally, CUDA installation and environment variable configuration are correct, and the environment variable is checked in QGIS. It is found that there is no C: \program files\NVIDIA GPU computing toolkit\CUDA\v10.2\bin in path.
Solution:
For the desktop, you can add C:\program files\NVIDIA GPU computing toolkit\CUDA\v10.2\bin
after the path in QGIS\bin\qgis-ltr-bin.env. For plug-ins developed in vscode, you can add o4w in the same folder, Change set path to set path =% osgeo4w in env.bat_ROOT%\bin;% WINDIR%\system32;% WINDIR%;% WINDIR%\system32\WBem;% CUDA_BIN_PATH%
