QUESTION

a loop to create a list of matrices generated from two different data frames in R

Asked 2021-Jun-14 at 17:39

I have two data frames. df1 and df2. both with c columns
using a clustering method, I ended up with 10 clusters. same clusters for each df is true. this means for example the 4th row of both df s go to the same cluster.
I added a cluster column to both dfs, showing the assigned cluster for each row.

I want to create a list.
this list contains 10 matrices, such that.
matrix 1, is a 2*c matrix. its first row is obtained by colmeans of those rows of df1 which are in cluster 1. and its 2nd row is obtained by colmeans of those rows of df2 which are in cluster 1.
and matrix 2 , colmeans of cluster 2 and so on.
this is what I ve done. but I get the 10th matrix only and not a list of matrices 1 to 10.
I would appreciate any help with this.

I am trying to scrape the NBA player names and projected fantasy score (not single stat DFS) using selenium. I've gotten as far as using selenium to automate clicking NBA, and selecting the fantasy score tab.

From there, I see the players in a grid where I will like to scrape the points and names for each player. I have attempted to loop through the grid but I don't think I'm doing it right

Can someone please take a look at my code and point me in the right direction ?

QUESTION

How can I reduce Try and Except statements in error-handling code

Asked 2021-Jun-12 at 00:07

Working on a project that updates a database. New values (Rows) are updated from a folder containing Excel files. The values in the Excel files are provided by employees. Sometimes these employees are still working in the Excel file while trying to update the database. This results in a PermissionError.

To avoid PermissionErrors, I use the Try and Except statement. This works fine but situations can occur that Excel files are not closed for a while and multiple Excel files are opened during the day.

Thus, just one Try and Except statement wouldn't work. Therefore I used three Try and and Except statements which still doesn't guarantee that errors are handled properly.

To solve this, I think a While loop or a break statement within the for loop would work? Tried to add a break statement at the end of the (first) except block but this didn't work..

Is there any way to tackle this? Adding more Try and Except statements would work, but that just seems silly.

Loop through dataframes in global environment and apply function to them

Asked 2021-Jun-11 at 03:54

I'm going to explain what my code is supposed to do:

First I import an arbitrary number of dataframes of the same number of columns and somewhat similar names (they're stock tickers).

Second, I create a function that changes the data type of the first column (from factor to date), deletes one column and finally adds an arbitrary number of columns as functions of the other columns (like returns, moving average, etc.)

Finally, since I'm working with plenty of dataframes, I want to apply this said function to all of them through a loop.

Now, as simple as this sounds, I've encountered many issues with the third step.

What I found online was this, to get all names of the dataframes in my environment:

I assume that you simply want to rotate the plot, add orientation="horizontal".
You can share the axis of subplots by setting sharex=True or sharey=True.
To share the range simply specify the limits of either axis: plt.xlim(0,4) and plt.ylim(-100,700)

Hadoop NameNode Web Interface

Asked 2021-Jun-09 at 14:18

I have 3 remote computers (servers):

computer 1 has internal IP: 10.1.7.245
computer 2 has internal IP: 10.1.7.246
computer 3 has internal IP: 10.1.7.247

(The 3 computers above are in the same network, these 3 computers are all using Ubuntu 18.04.5 LTS Operating System)

(My personal laptop is in another different network, my laptop also uses Ubuntu 18.04.5 LTS Operating System)

I use my personal laptop to connect to the 3 remote computers using SSH protocol and using user root : (Below ABC is a name)

computer 1: ssh root@ABC.University.edu.vn -p 12001
computer 2: ssh root@ABC.University.edu.vn -p 12002
computer 3: ssh root@ABC.University.edu.vn -p 12003

I have successfully set up a Hadoop Cluster which contains 3 above computer:

computer 1 is the Hadoop Master
computer 2 is the Hadoop Slave 1
computer 3 is the Hadoop Slave 2

======================================================

I starts HDFS of the Hadoop Cluster by using the below command on Computer 1: start-dfs.sh

Everything is successful:

computer 1 (the Master) is running the NameNode
computer 2 (the Slave 1) is running the DataNode
computer 3 (the Slave 2) is running the DataNode

I know that the the Web Interface for the NameNode is running on Computer 1, on IP 0.0.0.0 and on port 9870 . Therefore, if I open the web browser on computer 1 (or on computer 2, or on computer 3), I will enter the 10.1.7.245:9870 on the URL bar (address bar) of the web browser to see the Web Interface of the NameNode.

======================================================

Now, I am using the web browser of my personal laptop.

How could I access to the Web Interface of the NameNode ?

...

ANSWER

Answered 2021-Jun-08 at 17:56

Unless you expose port 9870, your personal laptop on another network will not be able to access the web interface.

You can check to see if it is exposed by trying :9870 to see if it is exposed. IP-address here has to be the global IP-address, not the local (10.* ) address.

To get the NameNode's IP address, ssh into the NameNode server, and type ifconfig (sudo apt install ifconfig if not already installed - I'm assuming Ubuntu/Linux here). ifconfig should give you a global IP address (not the 255.* - that is a mask).

Install dfs

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
