指定相互依存的链接库的顺序是错误的。
如果库相互依赖,则链接的库的顺序确实很重要。通常,如果库a
取决于库b
,则liba
必须在libb 在链接标志中。
例如:
// B.h
#ifndef B_H
#define B_H
struct B {
B(int);
int x;
};
#endif
// B.cpp
#include "B.h"
B::B(int xx) : x(xx) {}
// A.h
#include "B.h"
struct A {
A(int x);
B b;
};
// A.cpp
#include "A.h"
A::A(int x) : b(x) {}
// main.cpp
#include "A.h"
int main() {
A a(5);
return 0;
};
创建库:
$ g++ -c A.cpp
$ g++ -c B.cpp
$ ar rvs libA.a A.o
ar: creating libA.a
a - A.o
$ ar rvs libB.a B.o
ar: creating libB.a
a - B.o
编译:
$ g++ main.cpp -L. -lB -lA
./libA.a(A.o): In function `A::A(int)':
A.cpp:(.text+0x1c): undefined reference to `B::B(int)'
collect2: error: ld returned 1 exit status
$ g++ main.cpp -L. -lA -lB
$ ./a.out
为了重复重复,顺序做很重要!
加载文档后,在所有扩展的节点上触发conscl()
折叠它们:
$(document).ready(function(){
$('#tree').find('.sim-icon-d').each(function(){
$(this).click()
})
});
这应该是

您以错误的方式初始化的神秘性的,而
let myStyle = { color:'white', backgroundColor:'black' }
在DIV内部的样式参考时,
let myStyle { color:'white', backgroundColor:'balck' }
对于几个divs来说也是错误的,但它应该是样式的,但
也有一个div丢失,但可能是由于复制粘贴而引起的错误
阅读&amp;用初始化的var编写程序:)
尝试此代码以查看是否可以提供帮助 - 它简化了读取和处理
,并使其更可读
(用于维护和调试)。
有时,我们想打动人们并制作单线或紧凑的代码,从而牺牲可读性。我不建议这样做。
import itertools as it
K, M = map(int, input(), split())
# reading the K lines and appending lists to LL
LL = []
for i in range(K):
ll = list(map(int, input().strip().split()))
LL.append(ll[1:]) # skip the first num
MAX = -1
# looping thr Cartesian Product of LL lists and get the max now
for i in it.product(*LL):
MAX = max(sum(map(lambda x: x**2, i)) % M, MAX)
print(MAX)
鉴于您的规格我试图重现一个最小的例子。
您可以尝试做类似的事情:
#!/usr/bin/env bash
k="Y"
nr_0=("R" "R" "Y" "Y")
nr_1=("R" "Y" "Y" "Y")
nr_2=("Y" "R" "Y" "Y")
nr_3=("Y" "Y" "R" "Y")
nr_4=("Y" "Y" "Y" "R")
nr_5=("Y" "Y" "Y" "Y") # the winner
nr_6=("Y" "R" "Y" "Y")
for j in {0..6}; do
tmp_array_name="nr_$j[@]"
tmp_array=("${!tmp_array_name}")
if [ "${tmp_array[0]}" == "$k" ] && [ "${tmp_array[1]}" == "$k" ] && [ "${tmp_array[2]}" == "$k" ] && [ "${tmp_array[3]}" == "$k" ]; then
echo "The winner is $tmp_array_name - ${tmp_array[*]}"
fi
done
使用此输出:获胜者是NR_5 [@] -YYY Y
x,y,z坐标后的列是占用率。一个是0.74,另一个为0.31。作为具有构象的分子的一部分。如果在所有结构中都找到了它,则值将为1.00
编辑:
我在Python中使用CCTBX。我必须道歉,它实际上是在两天前工作,但是当我去给您写一个例子时,该包并未得到认可。我一直在遇到问题,让它再次工作。我正在使用Windows,而我只是移至Linux解决此问题。 CCTBX有过滤器,您可以在其中分开这些集合。 A,B等是Altloc位置。
基本格式是打开文件。隔离层,提取原子,用搜索创建真相表,然后在真相表上选择。
我没有明确地做到这一点,但是您应该能够在Altloc搜索
参考:
from __future__ import absolute_import, division, print_function`
from iotbx.data_manager import DataManager`
import pandas as pd`
dm = DataManager() # Initialize the DataManager and call it dm
dm.set_overwrite(True) # tell the DataManager to overwrite files with the same name
model_filename = "./files/1vir.pdb" # Name of model file`
m = dm.get_model(om_model_filename1) # Deliver model object with model info
pdb_hierarchy = m.get_hierarchy() # Get hierarchy object
pdb_atoms = pdb_hierarchy.atoms() # get atoms
sites_cart = m.get_sites_cart() # get atom list
sel_cache = pdb_hierarchy.atom_selection_cache()
#this next line may not be exactly right but along these lines, see reference
c_alpha_alpha_protein = sel_cache.selection("altloc A") # extract truth table
protein = sites_cart.select(c_alpha_sel_protein)
protein = sites_cart.select(c_alpha_sel_protein)
protein = pd.DataFrame( [i for i in protein], columns=['x', 'y', 'z'] )
# other examples that I know work`
# you can use other search parameters to set to isolate other components like solvents, ligands, etc.
c_alpha_sel_non_protein = sel_cache.selection("hetero") # isolate all non protein atom (ligand, H2O, AcOH...) XXX not case sensitive!
c_alpha_sel_proteinplus_not_ligand = sel_cache.selection("not resname 2ow") # XXX not case sensitive!
c_alpha_sel_ligand = sel_cache.selection("resname 2ow") # extract ligand truth table object
还有其他人做了自己的Python版本。只是浏览尚未使用:
prody如果您届时还没有得到一个示例,我将尝试将其放在一起。
之所以发生,是因为您的CSS选择器是错误的,它仅适用于桌子而不是项目。另外,您可以删除尝试以外的
,如果是“无”,则可以给链接一个默认值。
import scrapy
class ActaSpider(scrapy.Spider):
name = 'acta_spider'
start_urls = ['https://www.fcf.cat/acta/2022/futbol-11/cadet-primera-divisio/grup-2/1c/la-salle-bonanova-ce-a/1c/lhospitalet-centre-esports-b']
def parse(self, response):
for actaelements in response.css('table.acta-table tbody tr'):
yield {
'name': actaelements.css('a::text').get(),
'link': actaelements.css('a::attr(href)').get(default='Link Error'),
}
您可以使用.ondismiss()
使用类似的方法。
然后,使用ImageConverter
将您的ImageSlected
转换为base64字符串。
在profileView
中,
.sheet(isPresented: $openCameraRoll, onDismiss: didDismiss) {
ImagePicker(selectedImage: $imageSelected, sourceType: .camera)
}
func didDismiss() {
let b64Str = imageManager.imageToBase64(imageSelected)
print("\n---> b64Str: \(b64Str?.count) \n")
}
还删除ZSTACK
,或通过vstack
edit-1替换它:在这里,一些对我有用的示例代码:
struct ProfileView: View {
let imageManager = ImageConverter()
@State var changeProfileImage = false
@State var openCameraRoll = false
@State var imageSelected = UIImage()
var body: some View {
VStack {
Button(action: {
openCameraRoll = true
}, label: {
Image(systemName: "plus")
// .profileImageMod()
})
if changeProfileImage {
Image(uiImage: imageSelected)
.resizable() // <-- here
.frame(width: 222, height: 222)
.foregroundColor(.white)
.background(Color.gray)
.clipShape(Circle())
} else {
Image(systemName: "questionmark")
.frame(width: 222, height: 222)
.foregroundColor(.white)
.background(Color.gray)
.clipShape(Circle())
}
}
.sheet(isPresented: $openCameraRoll, onDismiss: didDismiss) {
ImagePicker(selectedImage: $imageSelected, sourceType: .camera)
}
}
func didDismiss() {
changeProfileImage = true
let b64Str = imageManager.imageToBase64(imageSelected)
print("\n---> b64Str: \(b64Str?.count) \n")
}
}
正如@iain Shelvington指出的那样,问题从用用户名
设置为uppercase
- &gt; 用户名= request.post.get('username')。upper()
。
user = User.objects.create_user(username=request.POST.get('username').upper(), email=request.POST.get('email').lower(), password=request.POST.get('password'), first_name=request.POST.get('firstname'), last_name=request.POST.get('lastname'))
然后,您将用户名
传递给authenticate()
没有upper()
。
user = authenticate(username=request.POST.get('username'), password=request.POST.get('password'))
因此,您可以在创建用户时从用户名中删除upper()
,或在authenticate() upper()
>。
不过,在附带说明,我看到您有两种称为login()
的方法。 django login()
和定义的方法login()
。这也可能给您带来一些问题。我建议您将定义的login()
重命名为:login_view()
,因此不会遮盖django login()
。例如:
# your defined method here; rename to login_view:
def login_view(request):
...
# so it won't shadow the login method from Django
login(request, users)
...
否则您会收到一个错误:
异常类型:typeerror at/login/except值:login()采用1个位置参数,但给出了2个
我发现了。工作查询是,
INSERT INTO community_members (community_id, member_id)
SELECT communities.id, user_follows.follower_id
FROM communities JOIN user_follows
ON communities.owner_id = user_follows.following_id
能够自动为每个社区所有者的用户做到这一点,而不必为每个用户运行查询是很酷的。目前还可以,因为我需要运行的15位用户进行
编辑:已更新以为所有社区所有者运行
更容易的解决方案是用阵列构造它(原始)。
否则,您可能会弄乱variadic模板和参数解开包装。
The easier solution would be to construct it with an array(in place).
Otherwise you can mess with variadic templates and parameter unpacking.
将新的构造函数添加到专用模板类
