我最近安装了 OpenNMT，但在浏览玩具示例时出现以下错误。

我有 macOS Big Sur 11.2.1 我安装了 python2.7 和 python3.9。

pip install --upgrade OpenNMT-py==2.0.0rc1

wget https://s3.amazonaws.com/opennmt-trainingdata/toy-ende.tar.gz

tar xf toy-ende.tar.gz

cd toy_ende

Traceback (most recent call last):

    sys.exit(main())

您可以按照以下步骤操作：

pip install --upgrade OpenNMT-py==2.0.0rc1;
wget https://s3.amazonaws.com/opennmt-trainingdata/toy-ende.tar.gz;
tar xf toy-ende.tar.gz;
echo '## Where the samples will be written
save_data: toy-ende/run/example
## Where the vocab(s) will be written
src_vocab: toy-ende/run/example.vocab.src
tgt_vocab: toy-ende/run/example.vocab.tgt
# Prevent overwriting existing files in the folder
overwrite: False

# Corpus opts:
data:
    corpus_1:
        path_src: toy-ende/src-train.txt
        path_tgt: toy-ende/tgt-train.txt
    valid:
        path_src: toy-ende/src-val.txt
        path_tgt: toy-ende/tgt-val.txt
' > toy_en_de.yaml;
mkdir toy-ende/run;
touch toy-ende/run/example.vocab.src;
touch toy-ende/run/example.vocab.tgt;
onmt_build_vocab -config toy_en_de.yaml -n_sample 10000;

echo '# Vocabulary files that were just created
src_vocab: toy-ende/run/example.vocab.src
tgt_vocab: toy-ende/run/example.vocab.tgt

# Train on a single GPU
world_size: 1
gpu_ranks: [0]

# Where to save the checkpoints
save_model: toy-ende/run/model
save_checkpoint_steps: 500
train_steps: 1000
valid_steps: 500
' >> toy_en_de.yaml;
onmt_train -config toy_en_de.yaml;

如果您没有 GPU，则需要删除或注释以下行：

# Train on a single GPU
world_size: 1
gpu_ranks: [0]
