For the record only，Please skip. After the blogger’s article，The blogger opened a new picture，After feeding the model-this problem occurred again：weight of size [ 64, 3, 7, 7], expected input[1, 4, 512, 1024] to have 3 channels, but got 4 channels instead That is, the original three-channel picture， ; After reading, it becomes four channels. Solution Add .convert('RGB')，Yes Image.open functionCaused That’s it. Thanks to the big blogger for the article ：Portal
Software Development_Python is the most popular, Java is the most popular, Go is the most promising, 7,000 programmers reveal the current status of software development in 2019
Preface: This article is organized by the editor of Programming Notes#. It mainly introduces Python, the most popular, Java, the most popular, and Go, the most promising. 7,000 programmers reveal the knowledge related to the current status of software development in 2019. I hope it will be useful to you. reference value. Author | Tu Min Organize Report source | JetBrains Produced by | CSDN (ID: CSDNnews) In the second half of the Internet, technology companies are increasingly facing a more severe competitive environment. Pay more attention to increasing revenue and reducing expenditure. And for the technical people who are in it and support half of the IT sky, what about now? From a technical point of view, what changes should be made to adapt to the trend? Next, we will start from The latest “2019 Developer Ecosystem” released by JetBrains Get a glimpse of the situation in the report “System Status”. JetBrains By surveying 7,000 developers around the world, we analyzed the The most commonly used languages and frameworks in daily software development, thereby exploring the latest trends in various programming technologies, hoping to help more developers acquire skills that suit themselves.

JavaScript variable:vara=(3,4,7);
It’s called the comma operator. By wrapping the right-hand expression in parentheses, we create a group and evaluate each of its operands and return The last value. From MDN The comma operator evaluates each of its operands (from left to right) and returns the value of the last operand. The comma operator is useful when you want to write a minifier and need to shrink the code. For example, print = () => console.log(‘add’) add_proc = (a,b) => a + b function add(a, b){ if(a && b){ print(); return add_proc(a,b) } else { return 0 } } console.log(add(1,2)); You can use the comma operator to reduce it as follows: print = () => console.log(‘add’) add_proc = (a,b) => a + b add = (a, b)=> a && b ?(print(),add_proc(a, b)):0 console.log(add(1,2)); 1> Mihai Alexan..: It is called the comma operator.
