399309171 MDU6SXNzdWUzOTkzMDkxNzE= 2676 Reshape function works only for numpy array and raise error with xarray variable. 15742456 closed 0     11 2019-01-15T11:46:56Z 2021-06-09T15:10:03Z 2021-06-09T15:10:03Z NONE      

Code Sample. raw is xarray.Variable (time: 12784, lat: 73, lon: 144). I am trying to reshape it.

```python

tmp= np.reshape(raw,(np.shape(raw)[0],np.shape(raw)[1]*np.shape(raw)[2])); Traceback (most recent call last):

File "<ipython-input-29-745611cba19c>", line 1, in <module> tmp= np.reshape(raw,(np.shape(raw)[0],np.shape(raw)[1]*np.shape(raw)[2]));

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/numpy/core/fromnumeric.py", line 257, in reshape return _wrapfunc(a, 'reshape', newshape, order=order)

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/numpy/core/fromnumeric.py", line 62, in _wrapfunc return _wrapit(obj, method, args, *kwds)

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/numpy/core/fromnumeric.py", line 46, in _wrapit result = wrap(result)

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/xarray/core/variable.py", line 1639, in array_wrap return Variable(self.dims, obj)

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/xarray/core/variable.py", line 259, in init self._dims = self._parse_dimensions(dims)

File "/Users/ahmedlasheen/anaconda2/lib/python2.7/site-packages/xarray/core/variable.py", line 420, in _parse_dimensions % (dims, self.ndim))

ValueError: dimensions (u'time', u'lat', u'lon') must have the same length as the number of data dimensions, ndim=2

```

Problem description

I got the previous error, which disappears once I use np.numpy(raw) instead of raw.

Expected Output

Output of xr.show_versions()
