我无法为python 2.7.12安装scikit-image
。
我第一次尝试安装scikit-image
是通过运行以下命令:
$ pip install -U scikit-image
但是,我收到一条错误消息:
对于Python 2.7,请使用以下命令安装0.14.x长期支持: $ pip安装'scikit-image <0.15'
我运行了上面的命令,但是对python 3.5有依赖性:
$ pip install 'scikit-image<0.15'

使用python 2.7安装scikit-image
是否必须安装<0.15 ...版本,但该版本需要python 3.5才有意义吗?
答案 0 :(得分:0)
尝试一下:
pip install scikit-image==0.14.1
答案 1 :(得分:0)
Scikit-image 0.15.0
的最新版本Python 2
不存在。
有关支持Python 2
的某些较旧版本,请参见软件包的pypi repository。另外,请检查您是否使用了正确的pip
。

如果同一台计算机上有两个Python版本,则应明确指定pip版本:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int count, /* integer amount from user */
odd_count = 0, /* odd count (initialized zero) */
even_count = 0, /* even count (initialized zero)*/
*number, /* declare pointers */
*evens,
*odds;
/* read in integer count from user (VALIDATE every input) */
printf("enter the amount of numbers: ");
if (scanf("%d", &count) != 1) {
fputs ("error: invalid integer input.\n", stderr);
return 1;
}
/* allocate count integers each pointer (VALIDATE every allocation) */
if ((number = malloc (count * sizeof *number)) == NULL) {
perror ("malloc-number");
return 1;
}
if ((evens = malloc (count * sizeof *evens)) == NULL) {
perror ("malloc-evens");
return 1;
}
if ((odds = malloc (count * sizeof *odds)) == NULL) {
perror ("malloc-odds");
return 1;
}
for (int i = 0; i < count; i++) { /* loop count times for input */
printf ("enter number %2d: ", i + 1);
if (scanf ("%d", &number[i]) != 1) { /* validate EVERY input */
fputs ("error: invalid integer input.\n", stderr);
return 1;
}
if (number[i] % 2 == 0) /* assign, increment evens count */
evens[even_count++] = number[i];
else /* same for odds */
odds[odd_count++] = number[i];
}
puts ("\n numbers\n--------"); /* output each array on its own */
for (int i = 0; i < count; i++)
printf ("%8d\n", number[i]);
puts ("\n evens\n--------");
for (int i = 0; i < even_count; i++)
printf ("%8d\n", evens[i]);
puts ("\n odds\n--------");
for (int i = 0; i < odd_count; i++)
printf ("%8d\n", odds[i]);
/* output all arrays together */
puts ("\nnumbers even odd\n-------- -------- --------");
for (int i = 0; i < count; i++) { /* loop printing number */
printf ("%8d", number[i]);
if (i < even_count) { /* if i < even_count */
printf (" %8d", evens[i]); /* output evens */
if (i < odd_count) /* if odds too, output them */
printf (" %8d\n", odds[i]);
else
putchar ('\n'); /* no more odds output '\n' */
}
else if (i < odd_count) /* if only odds left, output */
printf ("%18d\n", odds[i]);
else
putchar ('\n');
}
free (number); /* don't forget to free what you allocated */
free (evens);
free (odds);
}
为我工作的是2.7.15

提示出在您的错误消息中:
Collecting scipy>=0.17.0 (from scikit-image<0.15)

Complete output from command python setup.py egg_info:

raise RuntimeError("Python version >= 3.5 required.")
RuntimeError: Python version >= 3.5 required.
您获得了正确的scikit映像(0.14.2),但是现在SciPy收到的更新也与2.7不兼容,因此它本身会引发错误(请参见文件{{1}中的引发) }。)因此,您应该尝试.../scipy/setup.py
。
随着越来越多的软件包仅成为Py3.5 +,您可能需要再执行几个周期。

最合适:python2.7 -m pip install scipy==1.2.3
然后:python2.7 -m pip install PyWavelets==1.0.3
然后:python2.7 -m pip install scikit-image==0.14.5
