RuntimeError: Sizes of tensors must match except in dimension 1. Expected size 58 but got size 57 fo

An error occurred: When using yolo v5n for network training, the input size used is 900*900. When connecting the Feature Map of the 11th layer and the 6th layer at the 12th layer Concat, there is a problem of different dimensions. After running, the following error message appears: RuntimeError: Sizes of tensors must match except […]

Solution to the mismatch between the field name in the JSON string and the field name in the Java class (use of @JsonProperty(“”) and @JSONField(name = “”))

1.1 Background 1.1.1 The so-called background, that is, what is the purpose and reason for writing this blog? Recently, I encountered a very strange requirement at work. I used WebService to adjust a third-party interface, but the return value of the third-party interface was an Xml structure. It was not surprising at first. But then […]

Refined solution to the bracket matching problem and ultimate stack design: uncovering the mysteries of the largest stack and the smallest stack

Directory Bracket matching problem Minimum stack Maximum stack Max stack and min stack are two important variants of extreme stack. The max stack is used to store the maximum value of the current match, and the min stack is used to store the minimum value of the current match. Bracket matching problem Let’s take a […]

Harbin Institute of Technology Information Content Security Experiment 3–String Matching

1. Experimental purpose Be familiar with the AC or WM multi-pattern matching algorithm, implement the AC or WM string matching algorithm in a familiar high-level language, and evaluate the space and time complexity 2. Experimental requirements PS. I only did what I had to do and chose the AC [Must Do] 1: Implement the multi-pattern […]

Nvidia graphics card Failed to initialize NVML Driver/library version mismatch error solution

GPT has become quite popular recently, so I started to experiment with the GPU to run projects: https://github.com/OpenTalker/SadTalker Today I suddenly found that the program could not be used. After investigation, it was probably due to the inconsistency between the NVIDIA kernel driver version and the system driver version. The solutions to this error are […]

[AGC034D] Manhattan Max Matching

Problem Statement Snuke is playing with red and blue balls, placing them on a two-dimensional plane. First, he performed $N$ operations to place red balls. In the $i$-th of these operations, he placed $RC_i$ red balls at coordinates $(RX_i,RY_i)$. Then, he performed another $N$ operations to place blue balls. In the $i$-th of these operations, […]
