那些遗忘过去的人注定要重蹈覆辙。——乔治•桑塔亚纳
- Authorized error
刚开始按作者 GitHub 上的指示，当运行环境配置好，并且 make 之后，因为生成的 decompose.py 是可执行文件，直接运行
bell2014/decompose.py ../../original.png
就出现了这样的错误
import: not authorized `pd' @ error/constitute.c/WriteImage/1028
看到有相关问题的解答中提到
这是python脚本，不应该把它当成shell脚本运行，当然会报错
突然反应过来，我们通常在终端直接运行的可执行文件一般由 /usr/bin/sh 来作为默认执行器
而 .py 脚本需要显式指出 python 解释器，这样就有了解决方案，直接用 python 来运行就可以了啊

- namespacepath error
AttributeError: '_NamespacePath' object has no attribute 'sort'
该错误好像与 pip 有关，可以使用以下命令解决
sudo pip3 install --upgrade setuptools
-
numpy error
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
造成这个问题的原因是各种库之间的版本不匹配，numpy版本不合适，只需要把numpy降级到刚好满足需要的版本，就可以了。
Python packages (newer packages will likely work, though these are the exact versions that I used): PIL==1.1.7 cython==0.19.2 numpy==1.8.0 scipy==0.13.2 scikit-image==0.9.3 scikit-learn==0.14.1
将所用到的库的版本均降低了一些，没有使用最高版本的，这样就解决了错误。
cv@cv:~ $ sudo pip3 uninstall numpy
cv@cv:~ $ sudo pip3 install numpy==1.8.2
目前的版本如下所示
cv@cv:~ $ python3 >>> Python 3.5.2 (default, Nov 12 2018, 13:43:14) >>> [GCC 5.4.0 20160609] on linux >>> Type "help", "copyright", "credits" or "license" for more information. >>> import numpy >>> import scipy >>> import skimage >>> import sklearn >>> import PIL >>> numpy.__version__ '1.8.2' >>> scipy.__version__ '1.0.0' >>> skimage.__version__ '0.9.3' >>> sklearn.__version__ '0.19.0' >>> PIL.__version__ '6.0.0'
- cPickle error
在 python3 中使用如下代码会报错：
import cPickle as pk ImportError: No module named 'cPickle'
原因： python2 有 cPickle ，但 python3 是没有的，其对应的是 pickle
解决办法：将cPickle改为pickle即可
import pickle as pk
编程时要特别注意一下版本问题，因为 python3 并不兼容 python2。
- Unicode Decode Error
文件中语句如下
self.density = pk.load(gzip.open(data_filename, "rb"))
执行过程中一直报错
Traceback (most recent call last): File "bell2014/decompose.py", line 125, in <module> solver = IntrinsicSolver(input, params) File "/home/cv/li/mycode/github/intrinsic_test/bell2014/solver.py", line 26,in __init__ self.energy = IntrinsicEnergy(self.input, params) File "/home/cv/li/mycode/github/intrinsic_test/bell2014/energy/energy.py", line 14, in __init__ self.prob_abs_r = ProbAbsoluteReflectance(params) File "/home/cv/li/mycode/github/intrinsic_test/bell2014/energy/prob_abs_r.py", line 16, in __init__ self._load() File "/home/cv/li/mycode/github/intrinsic_test/bell2014/energy/prob_abs_r.py", line 66, in _load self.density = pk.load(f) UnicodeDecodeError: 'ascii' codec can't decode byte 0xfe in position 0: ordinal not in range(128)
想了一下，同时 Google 查了 gzip 和 pickle 的基本使用方法
一般都是这样
# 解压gzip文件示例: import gzip f = gzip.open('file.txt.gz', 'rb') file_content = f.read() f.close() # 创建gzip文件: import gzip content = "Lots of content here" f = gzip.open('file.txt.gz', 'wb') f.write(content) f.close() # gzip压缩现有文件: import gzip f_in = open('file.txt', 'rb') f_out = gzip.open('file.txt.gz', 'wb') f_out.writelines(f_in) f_out.close() f_in.close()
就想着试了一下，先把文件打开然后操作，操作完成再关闭
f = gzip.open(data_filename, "rb") self.density = pk.load(f) f.close()
果然还是不行，报同样的错误
UnicodeDecodeError: 'ascii' codec can't decode byte 0xfe in position 0: ordinal not in range(128)
看起来是解码的问题，试一下 utf-8
f = gzip.open(data_filename, "rb") self.density = pk.load(f, encoding='utf-8') f.close()
有点转机，错误提示改变了
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfe in position 0: invalid start byte
再试一下 iso-8859-1
f = gzip.open(data_filename, "rb") self.density = pk.load(f, encoding='iso-8859-1') f.close()
我的天，竟然可以了！通过了！
参考博客Python3：pickle加载文件产生UnicodeDecodeError
- xrang error
运行某代码时，报错
NameError:name ‘xrange’ is not defined
原因：在 python 3 中， range() 与 xrange() 合并为 range( ) 。我的 python 版本为 python3.5。
解决办法：将 xrange( ) 函数全部换为 range( )
