Pandas memory error
Problem description
I will use pandas to process data, which is known to all children’s shoes related to data processing. Read in from CSV file with a pd.read_csv, and then play as you like. Recently, when I was doing data preprocessing, I encountered a headache. Every time the program was executed to pd. Read_csv is always reported to memory error. Finally all kinds of search stackoverflow, finally find the crux:
Replace Python with X64
Yes, it’s as simple as that!
Attached to the
As anyone who has ever used Pandas knows, it is impossible to install Pandas in WIN without any trouble. With all kinds of dependence and the disgusting network in China, it may not be so easy to change Python into X64. Please don’t be impatient, and here comes the magic device:
Please use Anaconda, select an X64, download and install it directly, graphically, install the python X64 version with a full set of data analysis package, of course, there is a Python X64 version with ipython and other tools, not malicious, and even strongly recommend the first time you install Python directly to use this.
The end

How to share a process among multiple apks
By default, all components in the same application run in the same process, and most applications do, too. However, if we want to control that a particular component belongs to a process, we can configure it in the manifest file.
In the manifest entry for each component element (activity, service, receiver, provider), a “android:process” property is supported, which allows you to specify the process that a component is running. You can set this property so that each component runs in its own process, or you can have only certain components share a process. We want to be able to set the “Android: Process” property so that components in different applications, which share the same Linux user ID and have the same certificate, run in the same process.
< application> The element also has an “Android: Process” attribute that can be set to a default value that applies to all components.
When the amount of available memory is low and some processes that interact with the user in real time need memory, Android can terminate a process at any time. Components running in the terminated process are destroyed, but a second process is started when the components are needed to work again.
In deciding which processes to terminate, The Android system weighs their importance to the user. For example, it makes more sense to terminate a process running invisible activities than a process running visible ones. Whether or not to terminate a process depends on the state of the components that are running in the process.
If two activities cannot be placed in the same application, they can be forced to run in the same process by setting the following properties in their manifest, thus taking full advantage of the Shared resources within the process and reducing the memory footprint:
Java code:
(1) Set the same User Id:
2.< manifest android:sharedUserId=”aaa.bbb”
3. (2) The called activity sets the following properties:
4.< activity android:multiprocess=”true”
Or 5.
6.< activity android:process=”com.cienet.test”
For 3D OpenGL program, after modifying the above attributes, the memory footprint of the called activity will be significantly reduced, such as: 30MB-& gt; 2 MB.
You can do the following test: How do you share a process
Java code:
1. Join Android :sharedUserId=” AAA. BBB “no
2.android:process=”com.cienet.test”

Winscp failed to upload the file to the server, indicating permission denied with return code 3
Problem specification
When I am working on a project, the Permission Denied prompt will appear when I upload a file to the Linux server using WinSCP, with an error return code of 3. The error figure is as follows:
As you can see from the above error, the file upload failed because of insufficient permissions, because we connected to the server as a normal user, so the solution is to connect to the server as root user, so you have the right to upload files, so how to connect to the server as root user?Let’s take a look!
The solution
1. Check the path of SFTP service on your server
On the server using the command: cat/etc/SSH/sshd_config | grep SFTP
my server output: Subsystem SFTP/usr/libexec/openssh/SFTP server. –
2. Set the connection in winSCP
Set up your host name, port, user name and password. If you log in with a key instead of a password, you do not need to fill in the password. Then click Advanced and click SFTP, and the following interface will appear:
Pictured above Settings SFTP, only need to fill in the SFTP server with sudo/usr/libexec/openssh/SFTP server, sudo the back of the class capacity is the first step we by running the cat/etc/SSH/sshd_config | grep SFTP SFTP service path. After filling in the SFTP server, click shell and the following interface appears:
As shown in the figure above, you can set the shell by filling in sudo-I in the shell. If you are using the key to log in, then you need to click the verification under SSH, and the following interface appears:
Then select the key file. Click OK, click log in and connect to the server. At this point, we connect to the server as root. At this point, we can upload files normally.
