I am trying to import a module from a particular directory.
The problem is that if I use sys.path.append(mod_directory)
to append the path and then open the python interpreter, the directory mod_directory
gets added to the end of the list sys.path. If I export the PYTHONPATH
variable before opening the python interpreter, the directory gets added to the start of the list. In the latter case I can import the module but in the former, I cannot.
Can somebody explain why this is happening and give me a solution to add the mod_directory
to the start, inside a python script ?
This question is related to

pythonpath
When running a Python script from Powershell under Windows, this should work:
$pathToSourceRoot = "C:/Users/Steve/YourCode"
$env:PYTHONPATH = "$($pathToSourceRoot);$($pathToSourceRoot)/subdirs_if_required"
# Now run the actual script
python your_script.py
Temporarily changing dirs works well for importing:
cwd = os.getcwd()
os.chdir(<module_path>)
import <module>
os.chdir(cwd)
You could use:
import os
path = 'the path you want'
os.environ['PATH'] += ':'+path
As to me, i need to caffe to my python path. I can add it's path to the file
/home/xy/.bashrc
by add
export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH
.
to my /home/xy/.bashrc
file.
But when I use pycharm, the path is still not in.
So I can add path to PYTHONPATH
variable, by run -> edit Configuration.
