python - os.path.relpath not returning a relative path when using drive as start point -

-

why os.path.relpath, on windows, not returning proper relative path when using drive start point, either explicit or implied (current directory)

>>> os.getcwd() 'u:\\projects' >>> os.path.relpath(r'd:\foo\something', r"d:\\") '..\\foo\\something' >>> os.chdir("d:\\") >>> os.getcwd() 'd:\\' >>> os.path.relpath(r'd:\foo\something') '..\\foo\\something'     >>> os.path.relpath(r'd:\foo\something', r"d:\\foo") 'something'

i expecting see

'foo\\something'

or

'.\\foo\\something'

does have os.path.join note on windows?

note on windows, since there current directory each drive, os.path.join("c:", "foo") represents path relative current directory on drive

i using python 2.7

issue fixed under python 2.7.1

issue #5117: fixed root directory related issue on posixpath.relpath() , ntpath.relpath().

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
