The snorkel-extraction from snorkel-team

cannot import name 'SnorkelSession'

Just to clarify, my question is in regards to snorkel-extraction package as I am trying to run tutorial notebooks in this repo.

I looked at the other issues about the same problem in Snorkel repo. However I am still not able to figure it out.

I followed all the steps in the installation instruction successfully for snorkel extraction. When I load the tutorials notebook, none of the 'from snorkel' import works. Only 'import snorkel' command works.

I also downloaded the original Snorkel package and the notebooks there works without any problem. I am wondering if it's something new because of the change in Snorkel version? I was interested in running the advanced tutorials under Snorkel Extraction.

Thank you!

A little change about dataloader

When I try to run this tutorial, I found some bugs so I make a little change to dataloader
In numpy.load, the parameter 'allow_pickle' is false, if so, the dataloader will crack, so I changed it.
`class DataLoader(object):
def init(self, data_path='/data/'):
# fix SSL certificate issues when loading images via HTTPS
import ssl; ssl._create_default_https_context = ssl._create_unverified_context

    current_dir = os.getcwd()
    self.data_path = current_dir + data_path

    def load_train_attr(self):
        self.train_mscoco = np.load(self.data_path + 'train_mscoco.npy',allow_pickle=True)
        self.train_vg = np.load(self.data_path + 'train_vg.npy',allow_pickle=True)
        self.train_vg_idx = np.load(self.data_path + 'train_vg_idx.npy',allow_pickle=True)
        self.train_ground = np.load(self.data_path + 'train_ground.npy',allow_pickle=True)

        self.train_object_names = np.load(self.data_path + 'train_object_names.npy',allow_pickle=True)
        self.train_object_x = np.load(self.data_path + 'train_object_x.npy',allow_pickle=True)
        self.train_object_y = np.load(self.data_path + 'train_object_y.npy',allow_pickle=True)
        self.train_object_height = np.load(self.data_path + 'train_object_height.npy',allow_pickle=True)
        self.train_object_width = np.load(self.data_path + 'train_object_width.npy',allow_pickle=True)

    def load_val_attr(self):
        self.val_mscoco = np.load(self.data_path + 'val_mscoco.npy',allow_pickle=True)
        self.val_vg = np.load(self.data_path + 'val_vg.npy',allow_pickle=True)
        self.val_vg_idx = np.load(self.data_path + 'val_vg_idx.npy',allow_pickle=True)
        self.val_ground = np.load(self.data_path + 'val_ground.npy',allow_pickle=True)

        self.val_object_names = np.load(self.data_path + 'val_object_names.npy',allow_pickle=True)
        self.val_object_x = np.load(self.data_path + 'val_object_x.npy',allow_pickle=True)
        self.val_object_y = np.load(self.data_path + 'val_object_y.npy',allow_pickle=True)
        self.val_object_height = np.load(self.data_path + 'val_object_height.npy',allow_pickle=True)
        self.val_object_width = np.load(self.data_path + 'val_object_width.npy',allow_pickle=True)

    load_train_attr(self)
    self.train_num = np.shape(self.train_object_names)[0]
    load_val_attr(self)
    self.val_num = np.shape(self.val_object_names)[0]
    
    with open(self.data_path + 'image_data.json') as json_data:
        self.data = json.load(json_data`
