Numpy单元测试错误

Question

I have two unit test errors in numpy which i can't seem to decipher: I'm running Ubuntu 16.4

> Running unit tests for numpy
NumPy version 1.11.0
NumPy relaxed strides checking option: False
NumPy is installed in /usr/lib/python2.7/dist-packages/numpy
Python version 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]
nose version 1.3.

and then the errors are:

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/nose/loader.py", line 418, in        loadTestsFromName
addr.filename, addr.module)
File "/usr/lib/python2.7/dist-packages/nose/importer.py", line 47, in importFromPath
return self.importFromDir(dir_path, fqname)
File "/usr/lib/python2.7/dist-packages/nose/importer.py", line 94, in importFromDir
mod = load_module(part_fqname, fh, filename, desc)

ERROR: Failure: OSError (no file with expected extension)

Does anyone have an idea what might be the problem?

I had exactly the same error happening for numpy 1.11.0 and Ubuntu 16.04. I upgraded numpy to the most recent one [sudo] pip install --upgrade numpy , and then the tests worked.
