Java.lang.stackoverflowerror error. Finally, it is positioned as regular expression stack overflow. It is found that the data of some rows are matched too much by regular expression
the final solution is to enter the matching when the length of this row is less than 10000, otherwise null is returned
add the following code

[Solved] an error occurred when attempting to lock the volume

When using the burning tool win32diskimager to create the Ubuntu system boot disk, an error occurred

because the software was placed on the USB disk. Software and image files should be placed in other locations. Select the location of the created file under device.

Correct production process

    1. after opening the Win32 disk imager software, click the button under device, select the SD card, select the image file, and then click write. When the overwrite prompt message as shown in the figure below appears, click the “yes” button

    1. . There will be a progress display during the burning process. When the burning is completed, the progress bar reaches 100% and then disappears

    1. after burning, a successful prompt box will pop up, and click “OK” to complete the burning operation

**Gazebo error – [REST.cc:205] Error in REST request**

Gazebo error – [rest. CC: 205] error in rest request
summarize some problems encountered in today’s running navigation
this error message appears. Gazebo error – [rest. CC: 205] error in rest request is probably due to the problem in the following file
~ /. Ignition/fuel/config.yaml
put the
URL: https://api.ignitionfuel.org Use URL: https://api.ignitionrobotics.org replace ~ /. Ignition/fuel/config.yaml file.

After changing this file, there may be errors, but it will not affect the use
the reason is that we just changed the above file
for the problem we want to solve, we can refer to the following scheme
error code

[Err] [ClientConfig.cc:270] Parser error [4]

Ignore the error, as it doesn’t affect functionality.
Delete the configuration file ~/.ignition/fuel/config.yaml, which may be broken. The next time you launch Gazebo a new file should be created.

resolvent

Delete the superset.db database file and reinitialize the database

For example, my current Linux login user name is lane, and my superset.db file is in /home/Lane /. Superset/superset. DB , delete the file:

(superset) [layne@hadoop102 ~]$ cd /home/layne/.superset/
(superset) [layne@hadoop102 .superset]$ rm -f superset.db

Then reinitialize the database:

(superset) [layne@hadoop102 ~]$ superset db upgrade

Create the admin user again and find that it can be created successfully:

(superset) [layne@hadoop102 ~]$ export FLASK_APP=superset
(superset) [layne@hadoop102 ~]$ flask fab create-admin
Username [admin]: layne
User first name [admin]: 
User last name [user]:

failed call to cuInit: CUDA_ERROR_UNKNOWN: unknown error

Question

It was good before. After restarting the computer running program, this error is reported:

failed call to cuInit: CUDA_ERROR_UNKNOWN: unknown error
retrieving CUDA diagnositic information for host: ...

Then it runs with the old slow CPU.

environment

Ubuntu 20.04TensorFlow 2.5cudatoolkit 11.2cudnn 8.1

solve

The probability is that the graphics card driver is stained with something.

Because I happened to update the system (Ubuntu) automatically before, I probably moved some NVIDIA files or something. Then I can’t restart.

Then I opened the Software Updater, completely updated it, restarted it, and finished it.
