The previous section briefly introduces how to obtain user locations and use longitude and latitude to represent locations. This section describes geographical encoding.
First, we need to know what is geocode
Concept:
Geographic code: it refers to the process of establishing the spatial coordinate relationship between statistical data or address
. However, most of these services do not have a Python-specific library and are inconsistent with each other's JSON structure. As a geocoder, the disobedient python God made a special geocoding tool to unify the services of these different vendors.

What does it have to do with GPU,CPU? With this question, the Internet search for the relevant articles, found in the StackOverflow on the discussion on this. After reading their discussions in detail, it was foun

Call
Calls another batch program from one batch program and does not terminate the parent batch program. The call command accepts the label used as the calling target. If you use call outside of a script or batch file, it will not work on the command line.

In general, we only update a single record, but there are few batch updates. Currently, we provide three methods for batch update:
1. Batch update
Update test a set a. dept_no = (select B. dept_no from test1 B where a. emp_no = B. emp_no)
2. Batch update with multiple columns
Update test a set (A. emp_no, A. dept_no
Many recent viruses that have speculated about weak passwords are popular on the internet, such as the Worm.dvldr worm, which has been a serious one for a while. What these viruses have in common is the use of batches for ipc$ connections to guess that the administrator's password reaches the control server. The virus consists of several files and several complex batches. Batch processing is not a real programming, but some of its ideas and programmin
JDBC It provides a database batch capable of processing, in bulk data Services (extras, deletions, etc.). ), you can significantly improve system performance. I have a link to a project. In the absence of batch therapy, delete 5 about half an hour of data, the transformation, the use of batch processing method. Deleting 50,000 data will not be more than 1 minutes
JDBC provides the ability of database batch processing to significantly improve the performance of the system in the case of large volume operations (additions, deletions, etc.). I have contacted a project, in the absence of batch processing, delete 50,000 data about half an hour or so, and then the system to transform, using batch processing method, delete 50,00
Recently, many viruses with weak passwords have become popular on the Internet. For example, the Worm. Dvldr Worm, which has been very popular some time ago, is a typical one. One thing these viruses have in common is the use of batch processing for the ipc $ connection, so as to guess the Administrator's password to control the server. A virus consists of several files and several complex batches. Batch pr
In machine learning, the gradient descent (Gradient descent, GD) algorithm only needs to calculate the first derivative of the loss function, the calculation cost is small, it is very suitable for the training data very large application.The physical meaning of the gradient descent method is well understood, that is, the line is searched along the gradient direction of the current point, and the next iteration point is found. But, why does it derive the GD algorithm of

BAT (batch file or batch program) File Syntax and skills
First, the batch processing file is a text file. Each line of the text file is a DOS command.
Second, the batch processing file is a simple program. You can use if and goto to control the process and for to execute a command cyclically.
