[英]py2exe with import pyfits cause error
当使用导入pyfits在py文件中执行py2exe时,会导致错误。
如何避免这个错误?
我准备了test.py和test_setup.py(用于py2exe),如下所示。
test.py是一个简单的程序,用于显示参数指定的fitsfile数据。
在cmd.exe上:
\python test_setup.py py2exe
=>成功
\python test.py test.fits
[[[574 574 579 ..., 579 585 581]
[574 582 583 ..., 582 579 577]
[581 583 578 ..., 572 580 580]
...,
[584 585 580 ..., 584 582 579]
[585 583 582 ..., 586 575 578]
[584 580 583 ..., 585 585 589]]]
=>成功
\dist\test.exe test.fits
Traceback (most recent call last):

test.py
# -*- coding: utf-8 -*-
import sys
import pyfits
def showfits(path):
hdulist = pyfits.open(path)
imgs = hdulist[0].data
hdulist.close()
print imgs
if __name__ == "__main__":
showfits(sys.argv[1])
test_setup.py
# -*- coding: utf-8 -*-
from distutils.core import setup
import py2exe
option = {
"compressed" : 1 ,
"optimize" : 2 ,
"bundle_files" : 3
}
setup(
options = {
"py2exe" : option
},
console = [
{
"script" : "test.py"
}
],
zipfile = None
)
看这行崩溃了 :
dump.__doc__ += _tdump_file_format.replace('\n', '\n ')
似乎pyfits正在做一些类级别的docstring操作。 这可以合理地认为是一个错误,因为不能总是假定方法的__doc__
将是一个字符串,例如在使用优化编译的情况下(如您所愿),它可以去除所有docstring。
我认为最简单的解决方法是至少到现在为止禁用优化,或者修补pyfits以删除该行及其类似内容。
