在 spyder anaconda 中。
我已经通过 anaconda Prompt 安装了软件包 simpleitk,system,os 。
from __future__ import print_function
import SimpleITK as sitk
import sys
import os
def command_iteration(method) :
print("{0:3} = {1:10.5f} : {2}".format(method.GetOptimizerIteration(),
method.GetMetricValue(),
method.GetOptimizerPosition()))
if len ( sys.argv ) < 4:
print( "Usage: {0} <fixedImageFilter> <movingImageFile> <outputTransformFile>".format(sys.argv[0]))
cc
fixed = sitk.ReadImage(sys.argv[1], sitk.sitkFloat32)
print(sys.argv[1])
moving = sitk.ReadImage(sys.argv[2], sitk.sitkFloat32)
R = sitk.ImageRegistrationMethod()
R.SetMetricAsMeanSquares()
R.SetOptimizerAsRegularStepGradientDescent(4.0, .01, 200 )
R.SetInitialTransform(sitk.TranslationTransform(fixed.GetDimension()))
R.SetInterpolator(sitk.sitkLinear)
R.AddCommand( sitk.sitkIterationEvent, lambda: command_iteration(R) )
outTx = R.Execute(fixed, moving)
print("-------")
print(outTx)
print("Optimizer stop condition: {0}".format(R.GetOptimizerStopConditionDescription()))
print(" Iteration: {0}".format(R.GetOptimizerIteration()))
print(" Metric value: {0}".format(R.GetMetricValue()))
sitk.WriteTransform(outTx, sys.argv[3])
if ( not "SITK_NOSHOW" in os.environ ):
resampler = sitk.ResampleImageFilter()
resampler.SetReferenceImage(fixed);
resampler.SetInterpolator(sitk.sitkLinear)
resampler.SetDefaultPixelValue(100)
resampler.SetTransform(outTx)
out = resampler.Execute(moving)
simg1 = sitk.Cast(sitk.RescaleIntensity(fixed), sitk.sitkUInt8)
simg2 = sitk.Cast(sitk.RescaleIntensity(out), sitk.sitkUInt8)
cimg = sitk.Compose(simg1, simg2, simg1//2.+simg2//2.)
sitk.Show( cimg, "ImageRegistration1 Composition" )
在运行此代码时,它给我以下错误用法:E:/registration/simpleitk.py 发生异常,使用 %tb 查看完整的回溯。
系统退出:1
C:\Users\aBC\AppData\Local\Continuum\anaconda3\lib\site-packages\IPython\core\interactiveshell.py:3275:用户警告:要退出:使用“退出”、“退出”或 Ctrl-D。warn("要退出:使用 'exit'、'quit' 或 Ctrl-D。", stacklevel=1)
我怎样才能纠正这个错误?
