问题 I installed PyCrypto and Paramiko (in their respective directories) with python3 setup.py install and both were installed successfully. However, when I try import paramiko in the 3.2.5 interpreter, I get this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packages/paramiko/__init__.py", line 64, in <module> from transport import SecurityOptions, Transport ImportError: No module named

问题 I use regularly the __name__ property of classes in my code (which works perfectly in Python) but PyDev is always marking it as an error ( Undefined variable from import ). I tried to add the __name__ to the bulletin imports but this did not remove the problem. When I use auto completion, PyDev finds a __class__ property when typing a . behind a class which is wrong. But if I use __class__ property anyway, PyDev finds the __name__ property. Is there any bug in PyDev that has to do with mixing

问题 I am doing bioinformatics that has biopython dependency. Biopython always give me the following error: I hope someone could help me with this issue. Thank you! 回答1: This can occur on Biopython version >= 1.72 and has been discussed on the biopython mailing list here. This error occurs when you try and import while inside the biopython/ directory, to fix the error simply move to another directory outside the source tree and then execute your code. If the error still occurs then likely the

问题 I have a folder structure like this: setup.py core/ __init__.py interpreter.py tests/ __init__.py test_ingest.py If I try to import core in test_ingest.py and run it, I get an ImportError saying that the core module can't be found. However, I can import core in setup.py without an issue. My IDE doesn't freak out, so why is this error occurring? 回答1: When you import your package, Python searches the directories on sys.path until it finds one of these: a file called "core.py", or a directory

问题 I just successfully installed PyEphem using pip in a pyenv. However, on import I receive: ImportError: /python2.7/site-packages/ephem/_libastro.so: undefined symbol: PyUnicodeUCS2_AsUTF8String In looking around I've seen it mentioned that some modules are built "against Python" in regards to Unicode and suggest recompiling. I'm quite new to Python and Ubuntu 14.04, and although I believe this is the answer to my issue, I do not know what recompiling means or how to do it. 回答1: The symbol

问题 This question was already asked: the type android.widget.Filter.FilterResults is not visible But there was no clear answer, and now I'm getting the same problem. In that discussion there was something mentioned about variables being marked as final when they shouldn't be for the getFilter... Well, here is my code: package com.example.project; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.Locale; import android.app.Activity; import

问题 I've been struggling for hours on a problem that is making me insane. I installed Python 2.7 with Cygwin and added Scipy, Numpy, Matplotlib (1.4.3) and Ipython.

问题 I'm having problems while running a compiled source code. The code itself is correct and if I run python file.py everything goes fine; if I compile it with pyinstaller or software like this, and then I run the compiled file it says ImportError: No module named _cffi_backend . But when I open python and import cffi and/or _cffi_backend python doesn't show error. Investigating in my code I found that the problem is just with padding from cryptography, so if I don't import padding the output
