Python version: 3.6.9

Operating system (ubuntu linux, windows, ...): Ubuntu 16.04

Issue: Can not use bert sentance embedder due to the error. torch version '1.7.0+cpu'

Content or a name of a configuration file:

configs.embedder.bert_sentence_embedder

Command that led to error:

>>> from deeppavlov import build_model, configs
>>> m = build_model(configs.embedder.bert_sentence_embedder, download=True)
>>> texts = ['Hi, i want my embedding.', 'And mine too, please!']
>>> sent_max_embs, sent_mean_embs, bert_pooler_outputs = m(texts)

Hi!

DeepPavlov requires torch 1.6.0: https://github.com/deepmipt/DeepPavlov/blob/master/deeppavlov/requirements/pytorch.txt#L1

All needed requirements for a specific model could be installed with

! python -m deeppavlov install bert_sentence_embedder

Does changing torch version work for you?
