The sparse matrix of R language is too large to be used as.matrix

A very large matrix, with 320,201 rows and 8189 columns, would require 9.8GB if stored with a normal matrix of all zeros

cols <- 8189
rows <- 320127
mat <- matrix(data = 0, nrow=320127, ncol = 8189)
print(object.size(mat), unit="GB")
# 19.5 Gb
mat <- matrix(data = 0L, nrow=320127, ncol = 8189)
print(object.size(mat), unit="GB")
# 9.8 GbThe 0 here is actually to be distinguished

Here, 0L means that the data type is integer, which by default is numeric. The biggest difference between the two is that when you use 320127L * 8189L, you get a NA, whereas 320127 * 8189 does not
If you save it as a sparse matrix

mat <- Matrix(data = 0L, nrow=320127, ncol = 8189, sparse = TRUE)
print(object.size(mat), unit="GB")
#0 Gb
dim(mat)
#[1] 320127   8189

Although the number of rows and columns is the same, the sparse matrix occupies almost no memory. And the operations that ordinary matrices support, such as row sum, column sum and extraction of elements, are also possible in sparse matrices, but take a little more time. At the same time, there are many R packages that support sparse matrix, such as glmnet, an R package that does lasso regression.
Although sparse matrices look nice, parts of a sparse matrix that big in R can go wrong

> mat2 <- mat + 1
Error in asMethod(object) : 
  Cholmod error 'problem too large' at file ../Core/cholmod_dense.c, line 105

Even if I wanted to convert it back to the normal matrix with as. Matrix , it would still give me an error

> mat3 <- Matrix::as.matrix(mat)
Error in asMethod(object) : 
  Cholmod error 'problem too large' at file ../Core/cholmod_dense.c, line 105

Since the ready-made as. Matrix cannot be processed, what can be done?The simplest and roughest method is to create a new ordinary matrix, then traverse the sparse matrix and put the values of the sparse matrix back to the ordinary matrix one by one.

mat2 <- matrix(data = 0, nrow=320127, ncol = 8189)
for (i in seq_len(nrow(mat))){
    for (j in seq_len(ncol(mat))){
        mat2[i][j] <- mat[i][j]
    }
}

So how long does it take?My computer didn’t run for two hours anyway, so don’t test it.
Is there any way to speed it up?The way to speed up is to reduce the number of for loops, because we are a sparse matrix and most of the space is 0, we only need to assign the parts that are not 0 to the new matrix.
This requires us to understand the data structure of sparse matrices

> str(mat)
Formal class 'dgCMatrix' [package "Matrix"] with 6 slots
  ..@ i       : int(0) 
  ..@ p       : int [1:8190] 0 0 0 0 0 0 0 0 0 0 ...
  ..@ Dim     : int [1:2] 320127 8189
  ..@ Dimnames:List of 2
  .. ..$ : NULL
  .. ..$ : NULL
  ..@ x       : num(0) 
  ..@ factors : list()

@dim </code b> records the dimension information of the matrix, @dimnames </code b> records the row and column names, @x records non-0 values. @i that doesn't record a 0 row index corresponds to @x , all of which are 0, so it's not recorded. @p is more complex, it is not a simple record of non-0 value column index, look at the document also do not know what is, but through searching can find its conversion relationship with non-0 value column index.
Therefore, the code is optimized as

row_pos <- mat@i+1
col_pos <- findInterval(seq(mat@x)-1,mat@p[-1])+1
val <- mat@x
    
for (i in seq_along(val)){
    tmp[row_pos[i],col_pos[i]] <- val[i]
}

You can encapsulate it as a function

as_matrix <- function(mat){

  tmp <- matrix(data=0L, nrow = mat@Dim[1], ncol = mat@Dim[2])
  
  row_pos <- mat@i+1
  col_pos <- findInterval(seq(mat@x)-1,mat@p[-1])+1
  val <- mat@x
    
  for (i in seq_along(val)){
      tmp[row_pos[i],col_pos[i]] <- val[i]
  }
    
  row.names(tmp) <- mat@Dimnames[[1]]
  colnames(tmp) <- mat@Dimnames[[2]]
  return(tmp)
}

If you also need to improve, so may need to play Rcpp. I wrote a simple reference to http://adv-r.had.co.nz/Rcpp.html code, can come to my blog http://xuzhougeng.top/archives/R-Sparse-Matrix-Note to continue reading, can buy to continue reading in this paper.

There are errors 1304 and 2350 FDI server errors in ArcGIS Server installation

When I was in arcgis server 10.2 installation error 1304 problems, there is a file that cannot be written to, it’s about the (screenshots because before this is from online, looking for pictures)

Retry after 2350 FDI server error error dialog , Retry not, only can abort the
I checked on the Internet, many of them say system and uninstall the residual, But I just reinstalled the system, so there is no such problem.
later want to isn't me what is the problem of system, because when I right click the computer check management no local users and groups this option, wanted to take the computer in the past let the technician to look at, but a variety of reasons not to

later in my free time and want to try to install again, is suddenly thought of, because of the hard drive because before
because I added a solid-state drives to reinstall the system, when I install the arcgis is according to the previous habit before in mechanical drive, There was no problem when installing arcgis desktop, and then I did not think so much when installing the server. I installed it directly in the mechanical hard disk, and the result was wrong
. This time I installed it in the solid state hard disk, which is the system disk, and the installation went smoothly without any problem.
because I found that error 2350 FDI server error might be installed by the administrator without permission, but it did not work, so I suddenly thought about whether it was because the mechanical hard disk was not the system disk, and it was indeed the problem.
arcgis server can only be installed in the system disk because it needs the account permission of the system

Opening feature class.General function failure

When adding a ShapeFile to ArcMap, the following Error message occurs and the layer cannot be drawn: “Error opening feature class.General Function Failure “.
The reason:
Applockmgr. exe unregistered.ArcMap and ArcCatalog need this to help with shapeFiles.
Solutions:
Register applockmgr. exe.
1. Close ArcMap and ArcCatalog.
2. Open the command window: Start & GT; Application & gt;
3. Find the Bin folder in ArcGIS :
CD c:arcgisarcexe81bin
attention, in ArcGIS 9, the Bin folder is under c: Program FilesArcGIS, so the syntax should be :
CD c:Progra~lArcGISBin
4. Input :
regsvr32 aflockmgr. DLL
5. Input :
applockmgr.exe /regserver
6. Close the command window.

git terminal to the wrong, then I am in what cases reported in, is to build a personal blog, the day before is no problem, because the next morning, installation of a library, use the command CNPM install hexo – generator – search – save, after I baidu, some people say that is not ordered, because at that time, no progress has been the card and then cancelled, there may be, I feel CNPM uninstall hexo-generator-search –save. After using this command, I reported an error, too many of which were not saved.
wait until I use the heox d and the hexo g commands again, and I’m going to say the title is wrong
take a look at the picture:
the solution is to put the two packages in the next one:

see after the command is downloaded, the hexo g

Conclusion: NSS version problems cause curl error handling: YUM Update NSS

SQL Error (3621): String or binary data would be truncated The statement has been terminated. */

The error occurred when writing to the SQLServer database is as follows:
SQL Error (3621): String or binary Data would be truncated The statement has been. */
Reason 2.
The length of the field definition in the database table structure is smaller than the actual length of the field content to be written to, so it cannot be written
Iii. Solutions
The table structure fields can be successfully written after the length has been changed
 

Perfectly solve the error loading media: file could not be played error

Recently, I need to use JWplayer plugin to play videos. However, no matter which version or what kind of video I changed, it always prompts Error loading media: File could not be played incorrectly. I finally solved it after a lot of effort.
Solutions:
The IIS default configuration does not add an MP4 file, which results in opening an MP4 file 404.
Open the IIS manager, MIME type

Add, extension mp4, type Video/MP4

Click OK.

Dxly solves the fatal error of AutoCAD2006: unhandled access violation reading 0x0000 exception at 6532b0h.

dxlary
 
Autocad 2006 often fails to install when directly clicking Setup.exe, which says “AutoCAD2006-simplified Chinese installation has been terminated, please check” C :\DOCUME~1\** \ \ \ “LOCALS~1\Temp\ Autocad 2006 setup.log”. At this point, it can be solved by the following way: directly run AutoCAD2006\Bin\acadFeui\acad.msi to install, but when open CAD2006 after installation, it will encounter the following problems:
This is a fatal error. It has unhandled access to cheesy reading.
On the Internet for a long time do not know how to solve, one of the articles gave me inspiration. So I came to the following conclusion:
1. Click Setup.exe and it won’t install because Autocad2006 requires.net framework 1.1, while Windows 7 usually installs a higher version of.NET. When installing setup.exe, these plug-ins will be installed first. Check the “C :\ me ~1\***\ \LOCALS~1\Temp\AutoCAD 2006 setup.log”.
No plug-in is installed when running the ACad.mSI installation. Even if CAD2006 is installed, net 1.1 that supports CAD2006 is not installed and thus can cause a fatal error unhandled Access Cheesecourse at 6532b0h.
 
Based on the above inference, the problem was successfully solved in the following two ways:
A:
1. Run AutoCAD2006\Bin\acadFeui\ Support \ dotnetFX \ dotnetFx. exe manually install.net 1.1
2. Run setup.exe again to complete the installation.
Method 2:
1. Run AutoCAD2006\Bin\acadFeui\ Support \ dotnetFX \ dotnetFx. exe manually install.net 1.1
2. Run AutoCAD2006\Bin\acadFeui\acad.msi again to complete the installation.

socket.error : [errno 10048] and view PID process number and port number

A socket program recently written in python has run with an error:
socket.error: [Errno 10048] normally each socket address (protocol/network address/port) is allowed only once
After searching, it is found that this prompt appears when the port is in conflict. The possible reason is that after a Socket is created in the server program and a port is opened, the Socket is not closed at the end of the program. Therefore, this error prompt will appear next time the program is started.
1, at the end of the server program to close the Socket
2. Or change the port number
3. Restart the machine
Win7 system quickly check the port number and pid process number:
1. Press Win+R key, enter CMD, open the command line.
2. Enter netstat -aon|findstr in the CMD window to indicate the port number you want to see. Take netstat -aon|findstr 80 as an example:
3. As can be seen from the figure below, there is a program occupying port 80. On the far right is the process ID occupying the program: 2996;

4. Knowing the process ID, we just need to find out which program 2996 is. Continue typing the following command: tasklist|findstr “2996”, where 2996 is the previous process ID.
closes the corresponding process

    taskkill /F /IM httpd.exe

View port status

netstat -aon

package R does not exist

This error is usually the result of not writing or incorrectly writing the package name in the source file. Note that this error is consistent with the package name in the Androidmanifest.xml.

Link: fatal error lnk1123: failure during conversion to coff: file in

After VS2010 went through some updates, there was an error “Error LNK1123” when setting up the Win32 Console Project.

 
The solution is:
Step 1: change: project | project property | configuration property | listing tool | input and output | insert the option “yes” to “no” in the listing, but do this for every new project.
Step 2: change: item | item property | configuration property | connector | manifest file | embed the list option “yes” to “no”.
Step 3: Usually the computer will solve the problem after two steps of setup, but if there is still a problem, then click on the solution:
Is the computer a 64BIT operating system?If so, continue with the following:
Find if there are two Cvtres.exe.
One is C:\Program Files(x86)\Microsoft Visual Studio 10.0\vc\bin\cvtres.exe,
The other is C:\Windows\Microsoft.NET\Framework\v4.0.30319\cvtres.exe. Right-click the property | details to view both version Numbers, delete/rename the older version, or reset the Path variable.
   
Surprisingly, the cure is the third step: after you remove the old version of CVtres.exe, you don’t need to set the configuration every time.
