请将下列shell语句转换为python语句:if [ ${stage} -le 4 ] && [ ${stop_stage} -ge 4 ]; then echo "Prepare data, prepare requried format" # For wav feature, just copy the data. mfcc/fbank extraction is done in training for x in ${train_set} ${train_dev} ${recog_set}; do if [ $data_type == "shard" ]; then tools/make_shard_list.py --num_utts_per_shard $num_utts_per_shard \ --num_threads 16 data/$x/wav.scp data/$x/text \ $(realpath data/$x/shards) data/$x/data.list else tools/make_raw_list.py data/$x/wav.scp data/$x/text \ data/$x/data.list fi done fi

```python
import os
if stage <= 4 and stop_stage >= 4:
print("Prepare data, prepare required format")
for x in [train_set, train_dev, recog_set]:
if data_type == "shard":
os.system(f"tools/make_shard_list.py --num_utts_per_shard {num_utts_per_shard} --num_threads 16 data/{x}/wav.scp data/{x}/text $(realpath data/{x}/shards) data/{x}/data.list")
else:
os.system(f"tools/make_raw_list.py data/{x}/wav.scp data/{x}/text data/{x}/data.list")
```
注意:在 Python 中,使用 os.system() 函数来执行 shell 命令。在这个例子中,我们使用了 f-string 来将变量插入到 shell 命令中。由于变量名中带有下划线,因此需要将其转换为 Python 语法中的下划线。

请把下列shell语句转换成python语句:if [ ${stage} -le 0 ] && [ ${stop_stage} -ge 0 ]; then echo "stage 0: Setting up individual languages" ./local/setup_languages.sh --langs "${langs}" --recog "${recog}" fi
以下是将shell语句转换成Python语句的示例代码:
```python
if stage <= 0 and stop_stage >= 0:
print("stage 0: Setting up individual languages")
subprocess.call(['./local/setup_languages.sh', '--langs', langs, '--recog', recog])
```
请注意,`subprocess`模块需要导入以便调用外部脚本。如果您还没有导入此模块,请添加以下代码:
```python
import subprocess
```
请将下列shell语句转换为python语句:if [ ${stage} -le 5 ] && [ ${stop_stage} -ge 5 ]; then # Training mkdir -p $dir INIT_FILE=$dir/ddp_init rm -f $INIT_FILE # delete old one before starting init_method=file://$(readlink -f $INIT_FILE) echo "$0: init method is $init_method" num_gpus=$(echo $CUDA_VISIBLE_DEVICES | awk -F "," '{print NF}') # Use "nccl" if it works, otherwise use "gloo" dist_backend="nccl" cmvn_opts= $cmvn && cmvn_opts="--cmvn data/${train_set}/global_cmvn"
```python
import os
if stage <= 5 and stop_stage >= 5:
# Training
os.makedirs(dir, exist_ok=True)
INIT_FILE = f"{dir}/ddp_init"
os.remove(INIT_FILE) if os.path.exists(INIT_FILE) else None # delete old one before starting
init_method = f"file://{os.path.realpath(INIT_FILE)}"
print(f"{__file__}: init method is {init_method}")
num_gpus = len(os.environ["CUDA_VISIBLE_DEVICES"].split(","))
dist_backend = "nccl" if "nccl" in torch.distributed.available_backends() else "gloo"
cmvn_opts = ""
if cmvn:
cmvn_opts = "--cmvn data/{train_set}/global_cmvn"
```
注意:在 Python 中,使用 os.makedirs() 函数创建目录,使用 os.remove() 函数删除文件。在这个例子中,我们使用了 f-string 来将变量插入到字符串中。由于 $0 在 shell 中表示脚本名称,因此在 Python 中可以使用 __file__ 来表示当前脚本名称。在 Python 中,使用 os.path.realpath() 函数获取文件的绝对路径。
