+#DeepSpeech2 on paddle cloud
+
+## Run DS2 by public data
+
+**Step1: ** Make sure current dir is `models/deep_speech_2/cloud/`
+
+**Step2:**  Submit job by cmd: `sh pcloud_submit.sh`
+
+```
+$ sh pcloud_submit.sh
+$ uploading: deepspeech.tar.gz...
+$ uploading: pcloud_prepare_data.py...
+$ uploading: pcloud_split_data.py...
+$ uploading: pcloud_submit.sh...
+$ uploading: pcloud_train.sh...
+$ deepspeech20170727130129 submited.
+```
+The we can get job name 'deepspeech20170727130129' at last line
+
+**Step3:** Get logs from paddle cloud by cmd: `paddlecloud logs -n 10000 deepspeech20170727130129`.
+
+```
