[Solved] KeyError: ‘Transformer/encoderblock_0/MultiHeadDotProductAttention_1/query\\kernel is 

Recently, I've been working on the application of Transformer to fine-grained images.
Solving the problem with the vit source code
 
KeyError: 'Transformer/encoderblock_0/MultiHeadDotProductAttention_1/query\kernel is not a file in the archive'
 
This is a problem when merging paths with os.path.join
 
Solution.
 
1. In the modeling.py file
 
Add '/' to the following paths:
ATTENTION_Q = "MultiHeadDotProductAttention_1/query/"
ATTENTION_K = "MultiHeadDotProductAttention_1/key/"
ATTENTION_V = "MultiHeadDotProductAttention_1/value/"
ATTENTION_OUT = "MultiHeadDotProductAttention_1/out/"
FC_0 = "MlpBlock_3/Dense_0/"
FC_1 = "MlpBlock_3/Dense_1/"
ATTENTION_NORM = "LayerNorm_0/"
MLP_NORM = "LayerNorm_2/"
 
2. In the vit_modeling_resnet.py file
 
ResNetV2 class Add '/' after each 'block' and 'unit'
 
self.body = nn.Sequential(OrderedDict([
    ('block1/', nn.Sequential(OrderedDict(
        [('unit1/', PreActBottleneck(cin=width, cout=width*4, cmid=width))] +
        [(f'unit{i:d}/', PreActBottleneck(cin=width*4, cout=width*4, cmid=width)) for i in range(2, block_units[0] + 1)],
        ))),
    ('block2/', nn.Sequential(OrderedDict(
        [('unit1/', PreActBottleneck(cin=width*4, cout=width*8, cmid=width*2, stride=2))] +
        [(f'unit{i:d}/', PreActBottleneck(cin=width*8, cout=width*8, cmid=width*2)) for i in range(2, block_units[1] + 1)],
        ))),
    ('block3/', nn.Sequential(OrderedDict(
        [('unit1/', PreActBottleneck(cin=width*8, cout=width*16, cmid=width*4, stride=2))] +
        [(f'unit{i:d}/', PreActBottleneck(cin=width*16, cout=width*16, cmid=width*4)) for i in range(2, block_units[2] + 1)],
        ))),
]))

ERROR: Rancher must be ran with the –privileged flag when running outside of Kubernetes

According to the document on the official website of rancher 2.4, only one Linux host is required. Remember that a single node rancher server can be quickly deployed. Of course, this can only be used for testing. Deployment is very convenient. Just start dcoker on the host, and then start a container:

sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher

After the test, it is found that the container is constantly restarted after startup, and there is no way to enter the UI, prompting a network error.

Cause analysis:

bean instantiation failed

Solution:

There are three ways:

1. Comment out the following comments.

2.Servlet API dependency is missing. Add the following dependencies

 <dependency>
      <groupId>tomcat</groupId>
      <artifactId>servlet-api</artifactId>
      <version>5.5.23</version>
    </dependency>

Top35: pychar reports an error when connecting to MySQL server returns invalid timezone. Need to set ‘servertimezone’ property

Top35: Server returns invalid timezone. Need to set ‘ServerTimezone’ property.
Error content error cause solution

Content of the error

Error reason

Server returns invalid timezone. Need to set ‘ServerTimezone’ property.
The server returning an invalid time zone needs to set the ‘ServerTimeZone’ property.
reasons: MySQL driver jar package the default time zone was UTC
the UTC is the representative of a global standard time, but we use time is Beijing time zone that is east eight area, UTC eight hours ahead.
The solution
Joining together?ServerTimeZon =UTC
