Solve the problem of VC 6.0 fatal error C1033: cannot open program database’.\debug\vc60.pdb’

VC++6.0 compiled a few times, suddenly appeared

The always open a program database… debug\vc60.pdb

then compile has been the error information…

There are several sayings on the Internet:

The
The
1. File properties, change to archive line.

The
The
The 2.
Only need to modify the directory, because my original directory path contains Chinese, not recognized, all changed to English. This doesn’t happen on the Chinese version of XP.

3. Clean all, and then rebuild all!

The 4. It could be a memory leak in your program that causes a dead process!

I tried, looks like the above said method are not make for me,

then, he asked the elder brother of the ACM, they say just restart the VC6.0 with respect to OK, ha ha, problem is solved!!!!!! Well, then another big brother said he just had to shut down the project and turn it on. Well, I haven’t tried that yet…

alas, the power is off… I wanted to paste that article on VC6.0 detecting memory leaks later…

other: on CSDN

PDB is Program the meaning of the Database, recorded some information about the Program and debug the related information.
in the Project Settings can set whether to use PDB, by default is selected. If selected, this file will be automatically generated when recompiling.

The
The
The
other people say the solution is:

Edit-> If Preferences find: repositories is empty, change it to stdmod

The second method to modify the path is the solution to the problem I encountered, but it is not the optimal one. In fact, if you are careful, you will find that the compilation fails because of the Chinese scrambled code caused by the Chinese path, so solving the scrambled code problem should solve the problem.

The solution, of course, is to modify the format of the language’s advanced options.

Hanyu Formats and Language for Non-Unicode Programs choose Chinese.

After following the steps in the red box above

To Build – first & gt; The Clean, and then Build – & gt; Rebuild All

That solves the problem. This is much more convenient than changing the path, especially for Chinese projects where changing the name will make you cry

Declare my IDE environment:

Windows8.1 with UPDATE, English, Enterprise, VC6.0 SP6, the official original mirror file + official download SP6 patch, many castrated version of VC6.0 sometimes appear some puzzling mistakes, especially the Chinese version of VC6.0, even VC assistant VA are not used, as a developer, if fear of English, then I still advised you to change line.

There was an error when the code was compiled. The reason is that the code was copied from the web page and probably contained Chinese characters and other characters.
The solution: Remove the illegal ASCII characters

sklearn.metrics.mean_squared_error

Mean square error regression loss
format:
sklearm.mean_squared_error (y_true, y_pred, sample_weight=None, multioutput= ‘uniform_average’)
parameter:
y_true: true value.
y_pred: predicted value.
sample_weight: sample weight.
multioutput: multi-dimensional input and output, default is’ uniform_average ‘, calculates the mean square error of all elements, returns as a scalar; Alternatively, ‘raw_values’ computes the mean square error of the corresponding column and returns a one-dimensional array with the same number of columns.
example:

from sklearn.metrics import mean_squared_error
y_true = [3, -1, 2, 7]
y_pred = [2, 0.0, 2, 8]
mean_squared_error(y_true, y_pred)
# Output: 0.75
y_true = [[0.5, 1],[-1, 1],[7, -6]]
y_pred = [[0, 2],[-1, 2],[8, -5]]
mean_squared_error(y_true, y_pred)
# Output: 0.7083333333333334
mean_squared_error(y_true, y_pred, multioutput='raw_values')
# Output: array([0.41666667, 1.        ])
mean_squared_error(y_true, y_pred, multioutput=[0.3, 0.7])
# Output: 0.825
# multioutput=[0.3, 0.7]返回将array([0.41666667, 1.        ])按照0.3*0.41666667+0.7*1.0计算所得的结果
mean_squared_error(y_true, y_pred, multioutput='uniform_average')
# Output: 0.7083333333333334

maven Error occurred during initialization of VM Too small initial heap

Error occurred during initialization of VM
Too small initial heap

The above error occurred while using Maven. The solution is:

 export MAVEN_OPTS=-Xmx1024m

Caused by the “error string in namespace std does not name a type” error

A weird thing happened when I was learning c++ today: when compiling the following code, the compiler displayed an error:
error: ‘string’ in namespace ‘std’ does not name a type
The procedure is as follows:

struct sales_data
{
	std::string bookNo;
	std::string bookName;
	unsigned int count;
	double price;
};
int main()
{
	return 0;
}

obviously there is a #include< string>

However, if you modify the code as shown below, you will also compile successfully.
The modified code is as follows:

#include<iostream>
struct sales_data
{
	std::string bookNo;
	std::string bookName;
	unsigned int count;
	double price;
};
int main()
{
	return 0;
}

what is the reason for this?
After Google, at http://www.cplusplus.com/ query to the ios libraries and other libraries relationship is as follows:

As you can see from the figure above, the StringStream library has been declared in the IoStream library and includes some of the string functionality. So that’s what happened.

Log error SQL Error: 1062, SQLState: 23000

[Error resolution] paramiko.ssh_exception.SSHException: Error reading SSH protocol banner setting

Error message
In the morning, my colleague in the data group told me that there were several programs reporting errors. After checking the log, the error message was found:

paramiko.ssh_exception.SSHException: Error reading SSH protocol banner

After a search, it was revealed that the error was caused by the banner_TIMEOUT default setting being too short, only 15s.
Error analysis
See the transport code under Paramiko library. Py:

class Transport(threading.Thread, ClosingContextManager):
        self.banner_timeout = 15
        # how long (seconds) to wait for the handshake to finish after SSH

Reset the banner_TIMEOUT property value
Most of the methods on the Internet is to modify the source code, reinstall, feel a little trouble. I’m going to reset the properties in the code.

transport = paramiko.Transport((self.host, self.port))
print(transport.banner_timeout)
transport.banner_timeout = 30
print(transport.banner_timeout)

After testing, the two printed property values are different, indicating that the property is set successfully and the problem is solved.

What’s the matter with updating cydia “sub-process/usr/libexec/cydia/cydo returned anerror code (2)”?

Recently updated when cydia to the sub – process/usr/libexec/cydia cydo returned anerror code (2) of the scarlet letter is how to return a responsibility?
