我尝试在Google App Engine上导入PyML作为另一个库的要求,但是我收到以下导入错误:
File "/base/data/home/apps/s~myapp/uno.385079313378714244/PyML/__init__.py", line 4, in <module>
from PyML.containers import *
File "/base/data/home/apps/s~myapp/uno.385079313378714244/PyML/containers/__init__.py", line 3, in <module>
VectorDataSet = __import__('PyML.containers.vectorDatasets', fromlist=['']).VectorDataSet
File "/base/data/home/apps/s~myapp/uno.385079313378714244/PyML/containers/vectorDatasets.py", line 5, in <module>

File "/base/data/home/apps/s~myapp/uno.385079313378714244/PyML/containers/ext/ckernel.py", line 25, in <module>
_ckernel = swig_import_helper()
File "/base/data/home/apps/s~myapp/uno.385079313378714244/PyML/containers/ext/ckernel.py", line 17, in swig_import_helper
import _ckernel
ImportError: No module named _ckernel
我在网上搜索过这个错误,可以找到其他有问题的人,但没有给出答案。
UPDATE 导致错误的代码:
from sys import version_info
if version_info >= (2,6,0):
def swig_import_helper():
from os.path import dirname
import imp
fp = None
try:
fp, pathname, description = imp.find_module('_ckernel', [dirname(__file__)])
except ImportError:
import _ckernel
return _ckernel
if fp is not None:
try:
_mod = imp.load_module('_ckernel', fp, pathname, description)
finally:
fp.close()
return _mod
_ckernel = swig_import_helper()
del swig_import_helper
else:
import _ckernel
del version_info
答案 0 :(得分:1)
该代码似乎正在使用swig。 Appengine运行时沙箱将基于“c”的二进制库限制为受支持的集合。 Swig通常意味着用Python包装的编译C / C ++。所以看起来这不能在appengine上运行,除非他们有一个纯python选项。
您可以在托管VM下运行它。
您应该回过头来阅读有关Python沙盒的信息,以及它的局限性和直接支持第三方库的内容。
