Reason: the optimization software has shut down the auto start service of Autodesk.
Remember the error of using unaddressable value of a novice goer
Go test, report an error;
Error in go test panic: reflect: reflect. Value. Set using addressable value [recovered].
Solution: generally, there is an error of using unaddressable value, which indicates that the pointer value passed is incorrect. For example, if the pointer address needs to be passed, but the value is passed. At that time, I had a hunch that DB should have passed a non pointer when finding. After verification, it was.
So, the summary is: when updating in Gorm, you can not pass the pointer (if you want to use the returned primary key, you still need to pass the pointer), but when querying, you must pass it, even if it is slice or map type.

Python AttributeError: module ‘tensorflow‘ has no attribute ‘InteractiveSession‘
Error occurred while running tensorflow:
AttributeError: module 'tensorflow' has no attribute 'InteractiveSession'This is not the first mock exam error in the package, because the module Session has been removed in the new Tensorflow 2 version, and the code is changed to:
sess = tf.InteractiveSession()Replace with:
sess = tf.compat.v1.InteractiveSession()Similarly, if there are similar “TF. * *” codes in the code, you should add “compat. V1.” after them.
If you are not used to it, you can reduce the version of tensorflow

I’m not a professional, and my English is not good. I can’t understand what’s wrong. I have seen that there is no missing value in the date column of the file, and there is no date that does not conform to the format… This is very strange, welcome to leave a message, thanks in advance!
Solution
When converting, add a parameter errors ='coerce '.
reader = pd.read_csv(f'new_files/2020-12-22-5-10.csv', usecols=['passCarTime'],dtype={'passCarTime':'string'})
reader.passCarTime = pd.to_datetime(reader.passCarTime,errors='coerce')
reader.passCarTime.head()

[error record] Android application release package error handling (turn off syntax check log processing release configuration)
1. Turn off grammar checking
When Android applications are packaged, there will be a series of syntax checks, such as the placement of a layout file, which is cumbersome;
In build. Gradle under the module, configure as follows: check the syntax and ignore some minor syntax errors;
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
2. Log processing
According to the compilation type buildconfig.debug in the current compilation configuration, select whether to print the log;
public final class BuildConfig {
public static final boolean DEBUG = Boolean.parseBoolean("true");
public static final String APPLICATION_ID = "cn.zkhw.midi";
public static final String BUILD_TYPE = "debug";
public static final int VERSION_CODE = 1;
public static final String VERSION_NAME = "0.1";
}
If the current version is release, the value of buildconfig.debug is false;
Example of development log tool class log:
public class L {
public static void i(String TAG, String msg) {
if (BuildConfig.DEBUG)
Log.i(TAG, msg);
}
}
3. Release compiler optimization configuration
In general, the release release version needs the following configuration;
android {
buildTypes {
debug {
}
release {
zipAlignEnabled true
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

Read the configuration file in another way
