ImportError: No module named utils
I'm trying to import a utilities file but running into a weird error only when I run the code through a script.
When I run test.py
location: /home/amourav/Python/proj/test.py
code:
import os
os.chdir(r'/home/amourav/Python/')
print os.listdir(os.getcwd())
print os.getcwd()
from UTILS import *
The output is:
['UTILS_local.py','UTILS.py', 'proj', 'UTILS.pyc']
/home/amourav/Python
Traceback (most recent call last): File "UNET_2D_AUG17.py", line 11, in from UTILS import * ImportError: No module named UTILS
but when I run the code through the bash terminal, it seems to work fine
bash-4.1$ python
>>> import os
>>> os.chdir(r'/home/amourav/Python/')
>>> print os.listdir(os.getcwd())
['UTILS_local.py','UTILS.py', 'proj', 'UTILS.pyc']
>>> from UTILS import *
blah blah -everything is fine- blah blah
I'm running Python 2.7.10 on a linux machine
Your project looks like this:
+- proj
| +- test.py
+- UTILS.py
+- ...
If you like to import UTILS.py, you can choose:
(1) add the path to sys.path in test.py
import os, sys
sys.path.append(os.path.join(os.path.dirname(__file__), ".."))
# now you may get a problem with what I wrote below.
import UTILS
(2) create a package (imports only)
Python
+- proj
| +- test.py
| +- __init__.py
+- UTILS.py
+- __init__.py
+- ...
Now, you can write this in test.py if you import Python.proj.test
:
from .. import UTILS
WRONG ANSWER
I had this error several times. I think, I remember.
Fix: do not run test.py
, run ./test.py
.
If you have a look at sys.path
, you can see that there is an empty string inside which is the path of the file executed.
test.py
adds ''
to sys.path
./test.py
adds '.'
to sys.path
Imports can only be performed from "."
, I think.
