Well, delaying imports of optional dependencies of PyThaiNLP, like sentencepiece, pycrfsuite, and gensim, is fine (except Requests, which is a required dependency), but I think that delaying import statements of Python standard libraries, such as random, tarfile, and shutil, would make future maintenance work trickier, and would not impact much on the import speed?

I think it isn't impact the future maintenance because It uses only few function and use few time (train Perceptron model, download file, unzip file).
