I am running sympy on an external computer, but when I do the simple command
我在外部计算机上运行同情,但是当我执行简单命令时
M=sympy.zeros((2,2))
I get the error
我收到了错误
Traceback (most recent call last):
File "test.py", line 8, in <module>
M=sp.zeros((2,2))

raise ValueError('%s is not an integer' % n)
TypeError: not all arguments converted during string formatting
However, when I run it on my own computer, there is no problem. How can I fix this?
但是,当我在自己的计算机上运行它时,没有问题。我怎样才能解决这个问题?
The version on my computer is 0.7.1.rc1, while the one on the cluster is 0.7.6. Should I ask them to install the (older?) version or is there an easier fix??
我的计算机上的版本是0.7.1.rc1,而群集上的版本是0.7.6。我应该要求他们安装(较旧的?)版本还是更容易修复?

If you want a 2x2 matrix with zeros, try this:
如果你想要一个带零的2x2矩阵,试试这个:
In [6]: zeros(2,2)
Out[6]:
Matrix([
[0, 0],
[0, 0]])
or
要么
In [7]: zeros(2)
Out[7]:
Matrix([
[0, 0],
[0, 0]])
