In the solution for the pastebin/bitly system design, the write to cache flow is missing in the second diagram which refers to the scaling aspect. The cache has only a read arrow but not a write arrow. The diagram will be more intuitive if a write-through/write-back cache mechanism was indicated.

There are some interesting algorithms in simulation from Physics, Chemistry, and Engineering especially regarding Monte Carlo simulation: Heat Bath algorithm, Metro-Police algorithm, Markov Chain Monte Carlo, etc.

Huge and nice collection and also getting very much appreciated from the community.
It would be great if somebody can translate into English then it will be reaching out to global.

It says in the documentation (the last section - "Working with Virtual Environments"):

For Python 3 add the following lines to the top of your .wsgi file:

activate_this = '/path/to/env/bin/activate_this.py'
with open(activate_this) as file_:
    exec(file_.read(), dict(__file__=activate_this))

However `activate_this.p

In the given documentation, the mentioned key are acc and val_acc, but actually it is accuracy and val_accuracy.

Given documentation screenshot:

Whereas the actual keys are `dict_keys(['val_loss', 'val_accuracy

In = syntax,

• double quotes (")
• back slashes (\)
• non-ascii characters

are escaped in json.dumps:

$ http -v httpbin.org/post                                      \
    dquote='\"'                                                 \
    multi-line='line 1\nline 2'                               

Looks like www.python-requests.org and docs.python-requests.org are redirecting to https://2.python-requests.org and failing SSL negotiation, making the site appear down. Google links are all dead, documentation links don't work, etc.

http://2.python-requests.org redirects to https://requests.kennethreitz.org/en/master/, which works.

Expected Result

Website should appear or redirect to

SUMMARY

Since 2.9 mysql_db dump create dump with create database and use instruction.
Is that possible to add an option for using --no-create-db with a dump ?

COMPONENT NAME

Description

if MultinomialNB there is strange behavior of clf.coef_:
clf.coef_ is the same as clf.feature_log_prob_[1]

and

clf.intercept_ is the same as only one clf.class_log_prior_

for example
clf.feature_log_prob_[0][0:3]

array([-3.63942161, -3.17296199, -4.59417863])

clf.feature_log_prob_[1][0:3]

array([-3.51935008, -3.010937 , -6.41836494])

clf.coef_[0][0:3]

I think "outputs [-1]" and "outputs [0]" are equivalent (reversed) in this line of code, but the former (89%) works better than the latter (86%). Why?

Description

Hi, it seems that #3739 is not doing what the documentation describe:

os.environ.get('SCRAPY_CHECK') is returning None in my contract check.

Steps to Reproduce

1. Create a project from scratch
2. Add a random spider
3. Contract code is as follow

    def parse(self, response):

🚀 Feature

Add numerically stable cumulative logsumexp function. Also we have associated PR on cummax that is needed for numerically stable implementation (pytorch/pytorch#20240).

Motivation

This is useful when computing sum of probabilities and have different applications.

Pitch

Torch has cumsum and cumprod so I suggest logcumsumexp to be added.

• face_recognition version: 1.2.3
• Python version: 3.7
• Operating System: Debian 10.1

Description

face_detection need to scan "known_people" directory every time.
in "known_people" directory I've 20 people and face_detection need a lot of time to "learn" before search known peoples inside new photos (unknown_pictures directory contain 2 photos).
it's possible to cache "learn" anali

Description

The instructor in the above mentioned video has created a new version of the same tutorial, which can be found here

Why

It is always good to keep resources and tutorials up-to-date. The new video talks about namespaces, chroot and cgroups, and speaks about containers at a greater depth.

The release script fails silently after any keyboard input from the user. The release script can fail silently when given unexpected input. This can potentially delay the release by hours.

给定两个由小写字母构成的字符串 A 和 B ，只要我们可以通过交换 A 中的两个字母得到与 B 相等的结果，就返回 true ；否则返回 false 。

示例 1：

输入： A = "ab", B = "ba"
输出： true
示例 2：

输入： A = "ab", B = "ab"
输出： false
示例 3:

输入： A = "aa", B = "aa"
输出： true
示例 4：

输入： A = "aaaaaaabc", B = "aaaaaaacb"
输出： true
示例 5：

输入： A = "", B = "aa"
输出： false
 

提示：

0 <= A.length <= 20000
0 <= B.length <= 20000
A 和 B 仅由小写字母构成。

I think listing anti-patterns with some basic reasoning about "why not" is a good idea.

Example - singleton. Although #256 has "won't fix" label

• it is in PRs section, and people (if searching history at all) are searching issues first.
• it was misspelled, Singelton instead of Singleton, therefore impossible to find

Listing most popular anti-patterns (without actual implementation) shou

  Nu附带了一组内置命令（如下所示）。如果命令未知，命令将弹出并执行它（在 Windows 上使

Since we are moving to f-strings and dropping old strings formats (% and .format()), we no longer need to have the redundant %r and !r specifiers, instead we use the repr() format.

I was having a very hard time figuring out

fill = A.stack().mean()
A.add(B, fill_value=fill)

fill = 4.5. However I computed a value of 3.2 because I was taking the mean from the column of A not the DataFrame A.
This coming after the Indexing chapter where "explicit is better than implicit." I was thinking that this should be a little more explicit.
