Question

我尝试通过pip install在Windows 7中安装库PyDSTool。安装版本PyDSTool == 0.90.2。在此之前，我安装了依赖numpy和scipy。当我尝试将模块PyDSTool导入IDE python时，我收到类似这样的错误：

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    import PyDSTool
  File "C:\Python27\lib\site-packages\PyDSTool\__init__.py", line 77, in <module>
    raise RuntimeError("SciPy v0.5.1 or above is required")
RuntimeError: SciPy v0.5.1 or above is required

我更正了文件中的代码（C：\ Python27 \ lib \ site-packages \ PyDSTool__init __。py＆＃34;，第77行），以便

if tuple(vernums) < tuple([int(n) for n in "0.5.1".split(".")]):
    raise RuntimeError("SciPy v0.5.1 or above is required")
#if vernums[1] < 5:
#    raise RuntimeError("SciPy v0.5.1 or above is required")

因为scipy的版本= 1.0.0＆gt; 0.5.1 SciPy 1.0.0发布于2017-10-25

导入模块的下一次尝试给出了下一个异常

Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    import PyDSTool
  File "C:\Python27\lib\site-packages\PyDSTool\__init__.py", line 87, in <module>
    from .Events import *
  File "C:\Python27\lib\site-packages\PyDSTool\Events.py", line 13, in <module>
    from .Variable import *
  File "C:\Python27\lib\site-packages\PyDSTool\Variable.py", line 15, in <module>
    from .FuncSpec import ImpFuncSpec
  File "C:\Python27\lib\site-packages\PyDSTool\FuncSpec.py", line 17, in <module>
    from .Symbolic import QuantSpec, allmathnames_symbolic
  File "C:\Python27\lib\site-packages\PyDSTool\Symbolic.py", line 178, in <module>
    funcnames = [n for n in allmathnames if hasattr(eval(modlookup[n]+n),
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'sph_jn'

我玩了打印功能，发现 scipy.special 没有hava attr ＆＃34; sph_jn＆＃34; ，当python尝试eval时会出现此异常下一个代码

funcnames = [n for n in allmathnames if hasattr(eval(modlookup[n]+n), "__call__")]

任何人都可以帮我解决这个问题吗？

Answer 1

正如Warren已建议的那样，在parseUtils.py

中替换以下2行（第46-47行）

'h2vp', 'sph_jn', 'sph_yn', 'sph_jnyn', 'sph_in',
'sph_kn', 'sph_inkn', 'riccati_jn', 'riccati_yn',

到

'h2vp', 'spherical_jn', 'spherical_yn', 'spherical_in',
'spherical_kn', 'riccati_jn', 'riccati_yn',

将解决您的问题。

导入包PyDSTool不起作用
