Ubuntu14.04 installs Keras based on Anaconda and switches the backend to Theano
0 System version Ubuntu16.04
1 System update (the speed is very slow, you can try skipping this step to see if it will affect subsequent installations)
sudo apt updatesudo apt upgrade
2 Install python basic development package
sudo apt install -y python-dev python-pip python-nose gcc g++ git gfortran vim
3 Download Anaconda and then install it in the terminal, follow the prompts to complete
chmod 777 Anaconda.shsudo ./Anaconda.sh
4 Install Anaconda You can then choose to automatically add environment variables. If the python input in the terminal is not the version of Anaconda, you can modify it accordingly: check the environment variables. If python is retrieved under /usr/bin, since this is a soft link, you can delete the original soft link and create a new one pointing to Anaconda. python under.
-s ~/anaconda2/bin/python /usr/bin/python
5 In order to run conda in the terminal, if you have not added the environment variable, you can add the environment variable yourself: edit ~/.bashrc, add the environment variable (as shown below), and then source ~/.bashrc Or restart the terminal
export PATH=~/anaconda2/bin:$PATH
This also solves the problem in the previous step. The python version is the Anaconda version (more convenient than the solution in the previous step).
6 After changing, you can view the installed modules in the terminal
conda list
7 Download pycharm from the official website, decompress it and execute it. After running, search for the corresponding application in the dash and pull it to Taskbar as icon.
tar -xvf pycharm-community-2017.1.4.tar.gz cd pycharm-community-2017.1.4/bin ./pycharm.sh
8 Install tensorflow and keras and test
sudo pip install tensorflowsudo pip install keras python -c "import tensorflow"python -c "import keras"
9 Switch the backend to theonad: Find the configuration file: $HOME/ .keras/keras.json
, change <span class="hljs-attribute">backend</span>
field’s <span class="hljs-value"><span class="hljs-string">tensorflow</span></span>

Python is not strictly line-by-line execution, but is optimized and conditional execution based on the interpreter mechanism. The interpreter converts the code to bytecode, executed by the PVM, and may precompile constant expressions or optimize loops. Understanding these mechanisms helps optimize code and improve efficiency.

There are many methods to connect two lists in Python: 1. Use operators, which are simple but inefficient in large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use the = operator, which is both efficient and readable; 4. Use itertools.chain function, which is memory efficient but requires additional import; 5. Use list parsing, which is elegant but may be too complex. The selection method should be based on the code context and requirements.

There are many ways to merge Python lists: 1. Use operators, which are simple but not memory efficient for large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use itertools.chain, which is suitable for large data sets; 4. Use * operator, merge small to medium-sized lists in one line of code; 5. Use numpy.concatenate, which is suitable for large data sets and scenarios with high performance requirements; 6. Use append method, which is suitable for small lists but is inefficient. When selecting a method, you need to consider the list size and application scenarios.

In Python, a for loop is used to traverse iterable objects, and a while loop is used to perform operations repeatedly when the condition is satisfied. 1) For loop example: traverse the list and print the elements. 2) While loop example: guess the number game until you guess it right. Mastering cycle principles and optimization techniques can improve code efficiency and reliability.

To concatenate a list into a string, using the join() method in Python is the best choice. 1) Use the join() method to concatenate the list elements into a string, such as ''.join(my_list). 2) For a list containing numbers, convert map(str, numbers) into a string before concatenating. 3) You can use generator expressions for complex formatting, such as ','.join(f'({fruit})'forfruitinfruits). 4) When processing mixed data types, use map(str, mixed_list) to ensure that all elements can be converted into strings. 5) For large lists, use ''.join(large_li

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
