问题 I have the following directory: mydirectory ├── __init__.py ├── file1.py └── file2.py I have a function f defined in file1.py. If, in file2.py, I do from .file1 import f I get the following error: SystemError: Parent module '' not loaded, cannot perform relative import Why? And how to make it work? 回答1: since file1 and file2 are in the same directory, you don't even need to have an __init__.py file. If you're going to be scaling up, then leave it there. To import something in a file in the

问题 To preface, I think I may have figured out how to get this code working (based on Changing module variables after import), but my question is really about why the following behavior occurs so I can understand what to not do in the future. I have three files. The first is mod1.py: # mod1.py import mod2 var1A = None def func1A(): global var1 var1 = 'A' mod2.func2() def func1B(): global var1 print var1 if __name__ == '__main__': func1A() Next I have mod2.py: # mod2.py import mod1 def func2():

问题 Follow up to this I want to source scripts inside a given environment, like in sys.source , but "exporting" only some functions and keeping the others private . I created this function: source2=function(script){ ps=paste0(script, "_") assign(ps, new.env(parent=baseenv())) assign(script, new.env(parent=get(ps))) private=function(f){ fn=deparse(substitute(f)) assign(fn, f, parent.env(parent.frame())) rm(list=fn, envir=parent.frame()) } assign("private", private, get(script)) sys.source(paste0

问题 I have a simple module like this: #define MODULE #include <linux/kernel.h> #include <linux/module.h> #include <linux/init.h> int init_module(void) { struct inode { int i_ino; }; struct dentry { struct inode *d_inode; }; struct dentry *f_dentry; f_dentry = NULL; struct inode * p = f_dentry->d_inode; return 0; } void cleanup_module(void) { printk("Goodbye world\n"); } And my Makefile is like this: obj-m += oops.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C

问题 I have a simple C DLL that exposes functions from a static library. The DLL compiles without errors and I can run DUMPBIN on it to see the exports. However, when I attempt to load it with DllImport in C#, it says this: System.DllNotFoundException: Unable to load DLL 'ei.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). It's in the correct directory, for sure. So, I read that it might be a good idea to try Dependency Walker, in case I need to include

问题 For some reason, when I compile my app with Pyinstaller, it gives me an error when run: Traceback (most recent call last): File "<string>", line 2, in <module> AttributeError: 'module' object has no attribute 'activex' And the top of my code (the code itself is extremely long). I've also removed a whole load of arrays at the top, which contain text for the app. from wxPython.wx import * from wx import * from wx.lib.wordwrap import wordwrap import sys, os, re class CheatulousFrame(wxFrame):

问题 Ok, this is my files: memberDB.ts module MemberDB { interface Member { name: string; age: number; hobbies: string[]; } class Database { private members: Member[]; constructor(first ? : Member) { this.add(first); } add(member: Member) { this.members.push(member); } logMembers() { for (var member in this.members) { console.log(member); } } } } app.js ///<reference path="memberDB.ts"/> var db = MemberDB.Database; var Frank = { name: "Frank Arne", age: 38, hobbies: ['Baking', 'Swimming'] } db.add
