Hey guys, when i add interesting vector import my code, i display that error : TypeError: unsupported operand type(s) for +=: 'NoneType' and 'NoneType'
from sympy.vector import CoordSys3D, curl, divergence, gradient
from sympy.vector import *

These two imports do not cause me a problem in the current development version.

Sorry I couldn't explain. The SymPy(vectors) does work great at me as well. I meant on mobile phone. on mobile
SymPy ver==1.1.1
I can't update latest ver(1.10.1) yet. When I update SymPy 1.1.1 to 1.10.1 I display some '.rej' file with errors on my log.

If you are interested in manipulating vectors the following package built using sympy might be of interest -
https://galgebra.readthedocs.io/en/latest/
especially the way that the different products and derivatives
are implemented (the gradient of a scalar function f is simply
grad*f and the divergence of a vector function F is grad|F). It
will run in Juypter notebook. You define the type of coordinate
system you want by inputting a metrics tensor (rectangular,
cylindrical, and spherical are in the examples).

Yes I saw it. But I need sympy.vector in SymPy for usage mobile phone.

For what it is worth:
I use the free app Carnets Plus on my iPad ( and my iPhone ) and it works very well on my iPad!
I assume it should work on an iPhone, too - but I never really used it on my iPhone.

My problem is sympy.vector in SymPy 1.1.1 I guess. My package use SymPy 1.1.1 if I upgrade to SymPy 1.10.1(latest) occour a few errors during compile.

If you are getting errors just from imports, it is most likely that
the issue has to do with your installation. I would try removing SymPy
and reinstalling it. For instance, perhaps when upgrading somehow
files from the old version have been left around and are messing with
the new version.

I tried it... Actually while i following with usb debugging i see some errors these just from "from sympy.vector import ...."
My compiling using base library SymPy 1.1.1 in it. When I out off to "from sympy.vector import ...." from my main code everything is well.
Yes again some structures doesn't work, example: evaluate=True, plot3d(_one variable graph). But these unimportance to me.
As a natural I thought this problem cause by old SymPy version. Therefore I updating SymPy 1.1.1 to 1.10.1 or another 1.9... I display that error during compile:
STDOUT:
patching file sympy/utilities/timeutils.py
Hunk #1 FAILED at 8.
1 out of 1 hunk FAILED -- saving rejects to file sympy/utilities/timeutils.py.rej

It's not clear what you mean by "compile" (SymPy is pure Python and

does not need to be compiled), or what program you are using that
produces the above output (it looks like it is coming from 'patch' or
'git' maybe?).
Without more context, it's impossible to know what is going wrong.
None of the errors you have shown look like they are coming from SymPy
itself, but rather from a broken installation of it. I would repeat my
advice from before that usually your best bet when this sort of thing
happens is to just delete the environment and recreate it from
scratch.

Yes I found. Problem is by Compiler. it is pinning SymPy 1.1.1 and while I upgrade to up version it s giving some patching errors. Unfortunately this problem need editing to according to new SymPy version in patch.
