some error of eug.py

[zengkaiwei]

when I run semitrain.py no matter I use cluster or random it will report :No such file/directory: 'random_split/random_marker1501.pkl', the error code is in eug.py line406:
with open(load_path, "wb") as fp:
pickle.dump({"label set": label_dataset, "unlabel set":unlabel_dataset}, fp)

and another question: what's the mean of parser --sample cluster and --sample random

Maybe you can try "mkdir random_split" first. The "random" means randomly select samples from whole dataset to annotate, while the "cluster" means randomly select one sample from each cluster.
