Today, I need to plot font files in PNG format and save it, which sounds like a rare requirement. After browsing on the Internet, I found that it can use ImageFont module of Python package Pillow to solved.

At the beginning, I wanted to use the Python package fontTools to solve the problem, but later I found that the Imagefont module in Pillow was better.

If we want to processing date and time using Python, the datetime module that comes to minds first. The datetime module encapsulates Python’s date-related processing very well, and I have used it a lot in crawlers.

There is a most important thing I want to remind before I start: to use the Python interpreter of remote server requires the professional version of PyCharm. The community version has no way to configure the remote Python interpreter. (If I make a mistake, please feel free to tell me.)

Today when I reading the document of the “Transformers” package which Hugging Face developed, I suddenly discovered the model I build, its state is “eval()”, not “train()”. It seems that as long as we use “from_pretrained()” method is the default state “eval()”.

When I using PyTorch to train a model, I often use GPU_A to train the model, save model. But if I load the model I saved to test some new data, I always put the new data in a different GPU, we called it GPU_B.
