When using JPA to create a table, crazy errors are reported. It is clear that it is copying the last configuration file. How to report errors
I’ve been Baidu for most of the day. The reason is that some fields use database keywords
but it’s obviously impossible

 @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String bookId;
    @Column(updatable = false)
    private String bName;

In fact, because the ID field should be of integer type, I wrote it as string. It’s really a sunny pig
just modify it

Sparkcontext: error initializing sparkcontext workaround

Sparkcontext: error initializing sparkcontext workaround

Spark reports an error when configuring a highly available cluster
error sparkcontext: error initializing sparkcontext. Java.net.connectexception: call from Hadoop 102/192.168.10.102 to Hadoop 102: 8020 failed on connection exception: java.net.connectexception: connection rejected

This is because we configured spark logs to be stored in HDFS, but Hadoop was not opened after the spark cluster was started, resulting in an error when submitting tasks.

Solution:

    no longer store the event log
    find the spark installation directory/conf/spark-defaults.conf file, as shown in the figure, and comment out the corresponding event log part
    store the event log locally instead of in HDFS
    replace the directory in the second line in the figure above with the Linux local directory to start the Hadoop cluster (i.e. HDFS service)
    investigate the cause of the error, Or we configured the spark log to be stored in HDFS, but did not open HDFS, so start the Hadoop cluster

Problems and Solutions

According to the official project description:

This is because:
webrick has not been bound to Ruby since Ruby 3.0. Please refer to the link:   Ruby 3.0.0 Released   Description in.

Webrick needs to be added manually.

The added commands are:

bundle add webrick

Then we can solve the problem.

When Jekyll runs, it will prompt an error. Cannot load such file — webrick (LoadError) – Open Source – ossez

RuntimeError: Found dtype Double but expected Float”

RuntimeError: Found dtype Double but expected Float”

I made a mistake in finding the loss function,

resolvent:

target.float()

a=np.array([[1,2],[3,4]])
b=np.array([[2,3],[4,4]])

loss_fn = torch.nn.MSELoss(reduce=True, size_average=True)

input = torch.autograd.Variable(torch.from_numpy(a))
target = torch.autograd.Variable(torch.from_numpy(b))

loss = loss_fn(input.float(), target.float())

print(loss)

When the springcloud obtains the cloud link database information, an error is reported: errorcode 1045, state 28000

Today, when doing the micro service exercise, put the relevant information of the linked database on the code cloud warehouse, and configure application.yml through config to pull the data; An error occurs when querying the user’s Micro service connection database

Problem solving:

Wrap the running class in a package, which is the same level package as the other packages of the project

cv2.error: OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-buil

catalogue

The following operations are carried out under the windows environment.  

one   Change single slash to double slash

2. The modified path is in English

3. Delete CV2. Imshow ()

When I use CV2 to save pictures to a new price asking folder, I report an error CV2. Error: opencv (4.5.1) C: \ users \ appveyor \ appdata \ local \ temp \ 1 \ PIP req build

The solution is as follows:

The following operations are carried out under the windows environment.  

one   Change single slash to double slash

Some people on the Internet say that the path reading error is caused by the number in the path. Correction method: change the single slash in the path into double slash.

For example:

cv2.imwrite(save_dir + '\\' + img_name, img)

However, the same error is reported later, so read the following comments for 2 operations:  

2. The modified path is in English

I reported a similar error here because Chinese appears in the quoted picture path. If you change the picture path to an all English path, there will be no problem.   

for i in ori_imgs_single:
    img_name = i.split('\\')[-1]
    img = cv2.imread(i)
    cv2.imwrite(save_dir + '\\' + img_name, img)
print('save OK!')

OK：

3. Delete CV2. Imshow ()

Maybe there is something wrong with my environment. If you still report an error, try deleting CV2. Imshow (). If I delete it, it will be OK:  

 

  OK：

Domain error in object XXX “other” domain “other” rejected values and atm913

Question

When using the SSM framework for a project, the field error in object ‘xxx’ on field ‘xxx’: rejected value [[], [], []…] problem occurs.

resolvent

when the value passed from the front end is null, the value cannot be converted to the corresponding type, which will lead to loading

c

o

n

t

r

o

l

l

e

r

controller

The controller code reported an error before
for example:

u

r

l

:

url :

URL: ${pagecontext. Request. Contextpath}/book/toupdatepage/ ${book. Getbookid()}
if the red part is null, the field error in object ‘xxx’ on field ‘xxx’: rejected value [[], [], []…] problem will appear.

Therefore, to solve this problem, first check whether the value of the passed parameter is null, and then check whether the parameter type of the passed parameter is correct.

numpy.core._exceptions.MemoryError: Unable to allocate xxx GB

This error was reported during the training of 15W pieces of data recently, but I only used 60% of my local memory. After solving it, record it.

After checking, it should be the problem of Python bits. At first, my local is 32 bits.  

If your Python is 32-bit, your pandas and numpy can only be 32-bit. When your memory usage exceeds 2G, the memory will be automatically terminated

Later, it was changed to 64 bit, and there was no error
