python introduced its own package python error ModelNotFoundError

python error ModelNotFoundError

Probably because the working directory is not in sys.path, the system can not locate your default script file, you can solve the problem by following command:

Import SYS >>>
>>> sys.path.append ( 'D: \ python_test') # in parenthesis working folder path
>>> referenced module import mymodel #

 

Check the configuration of the path: the command line or in python .py file

import sys
sys.path

 

 

 

 

 

 Add the path by the command:

sys.path.append("C:\Users\DELL\Desktop\test")

In this way the path was added.

 

In python project, py file, we can use the following method

My file directory like this

pythonproject\main\data\test.py
pythonproject\main\common\mysqlutil.py

 

# test.py
import os

import sys
ProjectName = ' pythonproject ' 
# Get the current file 
curPath = os.path.abspath with (os.path.dirname ( __FILE__ ))
 # Print (curPath) 
# match project from the back 
# path curPath = [0: curPath.rfind (ProjectName)] 
rootPath curPath = [0: curPath.rindex (ProjectName)] + ProjectName
 Print (rootPath)
 # in parenthesis working folder path 
# modules referenced 
# sys.path.append (R & lt '\ path \ to \ file \ pythonproject \ main \ the Common ') 
# Import mysqlutil

# sys.path.append(r'\path\to\file\pythonproject')
# import main.common.mysqlutil
# from main.common import mysqlutil

# Sys.path.append (rootPath) 
sys.path.append (rootPath)
 # I own modules in the project are 
from main.common Import mysqlutil
