Installing QGIS

Question

I installed QGIS and I am having this message when I start qgis

Python error: Couldn't load plugin 'rastertool' due to an error when calling its classFactory() method See message log (Python Error) for more details."

Because of it I think I cannot make many processes when I use raster tools. I have tried to fix it but I cannot.

Do you know how I can fix it??

I use QGIS for windows and I use QGIS 3.4.14 version "Medeira"

Below is the whole error.

Couldn't load plugin 'rastertool' due to an error when calling its classFactory() method 

ModuleNotFoundError: No module named 'pandas'

"ModuleNotFoundError: No module named 'pandas'"

In order to solve your problem, you need to install the python module pandas. You can follow the following steps:

1. Find python.exe which is in your QGIS folder. (Example: C:\OSGEO4~1\apps\Python37)
2. Opens a command prompt
3. Type the following command: cd C:\OSGEO4~1\apps\Python37 & python -m pip install pandas

Tell me if the installation of the module is done correctly and if your problem is solved.
