execute python script question

[Gabriel Rossetti]

Hello,

I have been developping something in python that has the following 
hierarchy :

project/src/myPackage/
project/src/myPackage/__init__.py
project/src/myPackage/module1.py
project/src/myPackage/module2.py
project/src/myPackage/test/
project/src/myPackage/test/__init__.py
project/src/myPackage/test/test_module1.py
project/src/myPackage/test/test_module2.py
project/src/myPackage/mySubPackage/__init__.py
project/src/myPackage/mySubPackage/module1.py
project/src/myPackage/mySubPackage/test/
project/src/myPackage/mySubPackage/test/__init__.py
project/src/myPackage/mySubPackage/test/module1.py
...

up until now, I had been executing my modules from inside 
project/src/myPackage/
but I realised that that is wrong (while implementing the test suite) 
and that since all my modules had relative imports (if module2 needed 
module1, it would just say : import module1) I changed them to 
myPackage.module1 for example. Now my test suite is happy, I can say : 
test.sh myPackage.test and it tests everything. The only problem now is 
that I can't execute the scripts from inside or outside the myPackage 
dir, I get this :

from outside :

Traceback (most recent call last):
  File "myPackage/module1.py", line 15, in <module>
    from myPackage import constants, utils
ImportError: No module named myPackage

or if from inside it :

Traceback (most recent call last):
  File "module1.py", line 15, in <module>
    from myPackage import constants, utils
ImportError: No module named myPackage

can anybody please help me? I don't think I understood the whole 
package/module thing I think... I think some people do some sort of 
importing in the __init__.py files but I'm not sure this helps in this case.

Thanks,
Gabriel
