minpy.numpy.sqrt() error

[jacklxc]

I was using OnlyNumpyPolicy in older version of minpy. After updating minpy, I could not use OnlyNumpyPolicy anymore. As a result, basic operations such as

import minpy.numpy as np
a = np.sqrt(2)

Causes errror:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/lixiangci/minpy/minpy/primitive.py", line 134, in __call__
    return self.call(args, kwargs)
  File "/Users/lixiangci/minpy/minpy/primitive.py", line 221, in call
    result_value = self._func(*arg_values, **kwarg_values)
  File "/Users/lixiangci/mxnet/python/mxnet/_ctypes/ndarray.py", line 104, in generic_ndarray_function
    raise ValueError("Too many positional arguments")
ValueError: Too many positional arguments

Personally I suggest developers to enable OnlyNumpyPolicy again to solve this problem.

Thank you.

This is because MXNet's sqrt call does not accept single scalar as argument. We will PR to MXNet to fix this problem.

@jermainewang Many functions in minpy don't accept scalar and list arguments, however numpy does. I think minpy should be consistent with that in numpy.

@wangg12 The fix is still on the way.
