After updating the scaffold and creating a new project, NPM run serve reported this error
directly using the method
1. At the beginning of Vue create XXX, check the CSS when you check the pre selection
but this method is not good, sometimes you just don’t want to check what to do.
2. Update the webpack, and update all other updates. This should be ok……
Problem Description: BTS code today, all kinds of errors. The amazing thing is that everyone has no problem, only I encounter all kinds of wonderful problems, which are too difficult.
Type error: can’t convert CUDA: 0 device type tensor to numpy. Use tensor. CPU () to copy the tensor to host memory first
The solution to this problem is to copy the GPU data to the CPU first, and then save it. But it doesn’t look like that to me. Some people encountered it before because the torch version was wrong, so I reloaded all kinds of versions and combinations, which were unsuccessful.
Only part of the code will be commented out first, and then take a closer look.
Question 2: typeerror:__ array__() takes 1 positional argument but 2 were given
This problem is even more exotic, the image reading error. It is roughly the following situation:
np.array(img) # OK
np.array(img, dtype=np.float64) # ErrorAfter searching for a long time, I finally found that a big guy proposed that it was a PIL bug, and the version was lowered from 8.3 to 8.2 to solve it
Vue cli4.5.13 build vue3 project failed to start
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

Error: when the value of row is obtained in sparksql and the field of row allows null, null is obtained when the value is taken and assigned to a new variable name. A NullPointerException error will be reported
Solution: you can first use row. Isnullat (index) to determine whether the value of the field is empty
Specific cases are as follows:
First, make mistakes
If row. Isnullat (6) is not empty, the value will be assigned to the variable
When you get a value from row, you often encounter the problem of being empty.
the simple summary is as follows:
get value type: if it is empty, it will be converted to 0
to judge null. It is recommended to use row.isnullat (index)
Get string type: if it is empty, it will be null
if it is empty, it is recommended to use: stringutils. Isempty() (in case of ″)
Summary: getast
is used to get values, row. Isnullat
and stringutils. Isempty ()
There are no write permissions. You need to change the permissions for the folder
sudo chown -R wh /home/wh/anaconda3
Let’s move it, let’s move it, let’s move it, let’s go, let’s go, let’s go, let’s go, let’s go, let’s go, let’s go, let’s go.

We’re going to go to the floor, we’re going to go to the floor, we’re going to go to the floor, and we’re going to go to the floor, and we’re going to find where the wrong thing is:
we’re going to go to 
and we’re going to get grad-6.7.1
Today, I use phpstudy to open the MySQL database, and then connect to the database failed: the report is 1049, which means that the database does not exist.
The error is as follows
. In this CMD window, you can go all the way up to the time when you just connected the data
to see if your database name is right, but my database name is wrong
config file, which contains the
default.json file. There is a
database, fill in your own correct database name in the database, and then connect to the database after saving it
this way means success, and I hope it will help you with your mistakes!!!
After tossing all afternoon, I began to think that it was the problem of using JPA warehouse. I replaced the simplest JPA repository, but it still couldn’t work. I checked online and tried the following methods:
Delete the version number;
Delete all the files in the folder (. M2) and then import the package again by Maven;
At a loss, I found that I had commented on the main startup class
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
It’s equivalent to not allowing automatic injection of data source. Of course, entitymanagerfactory can’t be found…
Hope to be able to help small partners who encounter the same difficulties!
Using sudo apt get install ROS melodic TEB local planner
to install the software, this error is reported, and the solution found can not be used
later, it is found that there is this file in the mirror source, but the previous one is all right, and the suffix of the upload date is wrong, which leads to the failure to find the installed package
after searching, it is found that there is a problem with DNS resolution
Solution:
change DNS first https://note.qidong.name/2020/05/resolvconf/
Modify the/etc/resolv.conf file, add 202.106.0.20
this is from Beijing Unicom, and then execute sudo apt get update
to get the result
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu bionic Release: The following signatures were invalid: EXPKEYSIG F42ED6FBAB17C654 Open Robotics <[email protected]>

W: Some index files failed to download. They have been ignored, or old ones used instead.
Such an error report
execute sudo apt key adv — KeyServer keyserver.ubuntu.com — recv keys f42ed6fbab17c654
the following key is the key on the error report, just copy it
Then execute sudo apt get update
and finally sudo apt get install ROS melody TEB local planner
successfully!
The error is as follows
