Function "addcyclic": IndexError

[Yixin]

Hi, I am using "addcyclic" function and encounter the Index Error. Error details are:

IndexError Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_11852/1134487354.py in
6 m.drawmeridians(np.arange(0.,360.,90.),linewidth=0.4,color='gray',labels=[True,True,True,True])
7 #在Py3.7下使用basemap==1.2.0，在循环填白addcyclic时可能会报错
----> 8 psi_p1,lon1=addcyclic(np.array(psi_p),np.array(lon))
9 lonsn, latsn = np.meshgrid(lon1, lat)
10 x_cyc,y_cyc=m(lonsn,latsn) #建立投影坐标映射

5101 return _addcyclic_lon(arr[-1])
5102 else:

5086 raise ValueError('The specified axis does not correspond to an '
5087 'array dimension.')
-> 5088 return npsel.concatenate((a,a[slicer]),axis=axis)
5089 def _addcyclic_lon(a):
5090 """addcyclic function for a single longitude array"""

IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices

The code is:
psi_p1,lon1=addcyclic(np.array(psi_p),np.array(lon))

Here is the variable psi_p: https://box.nju.edu.cn/f/64583aedd0c24eae909d/
lon: https://box.nju.edu.cn/f/a273d137b454468c8007/

Software and module versions are: Python 3.8.8, numpy 1.23.5, basemap: 1.2.2

I am wondering whether it is due to inconsistency of package version? Is it possible to fix the bug without reinstall python or modules due to interdependence of a lot of my other modules. Thanks a lot!!

Hi @YixinNJU! This error sounds like #555, which was solved for basemap release 1.3.5. Can you try upgrading to the latest basemap version (currently 1.3.7)? The version 1.2.2 is a bit outdated. The version 1.3.7 is available at conda-forge for Windows x64 (presumably your OS and architecture).

Thank you for your reply! I upgraded basemap to 1.3.7 and re-import the module, the same Index Error still exists.
