This must be a trivial question:
I have "import numpy as np" in the python startup file.
A file called mod1.py contains "def myfn..."
and inside myfn there is a call to, say, "np.convolve".
Interactively:
python
.... (numpy imported as np)
import mod1
mod1.myfn(...)
Error: global name "np" is not known.

Why is "np" not known to functions in an imported module ?

I can fix this by including "import numpy as np" in any module that uses numpy
functions -- but then what is the point of having a startup file?
That "fix" is indeed the way things are done. Modules only know about what
they import or create*.
The point of the startup file is to have things ready for interactive investigation -- if you use numpy *alot* then
having it already there beats the heck out of typing `import numpy as np` every time you start the interpreter.
