+# Visual DL Toolset
+
+
+ 
+
+
+## Introduction
+VisualDL is a deep learning visualization tool that can help design deep learning jobs.
+It includes features such as scalar, parameter distribution, model structure and image visualization.
+Currently it is being developed at a high pace.
+New features will be continuously added.
+
+At present, most DNN frameworks use Python as their primary language. VisualDL supports Python by nature.
+Users can get plentiful visualization results by simply add a few lines of Python code into their model before training.
+
+Besides Python SDK, VisualDL was writen in C++ on the low level. It also provides C++ SDK that
+can be integrated into other platforms.
+
+
+## Component
+VisualDL provides following components:
+
+- scalar
+- histogram
+- image
+- audio
+- graph
+- high dimensional
+
+### Scalar
+Scalar can be used to show the trends of error during training.
+
+
+
+
+
+### Histogram
+Histogram can be used to visualize parameter distribution and trends for any tensor.
+
+
+
+
+
+### Image
+Image can be used to visualize any tensor or intermediate generated image.
+
+
+
+
+
+### Audio
+Audio can be used to play input audio samples or generated audio samples.
+
+### Graph
+Graph is compatible with ONNX ([Open Neural Network Exchange](https://github.com/onnx/onnx)),
+Cooperated with Python SDK, VisualDL can be compatible with most major DNN frameworks, including
+PaddlePaddle, PyTorch and MXNet.
+
+
+
+
+
+### High Dimensional
+High Dimensional can be used to visualize data embeddings by projecting high-dimensional data into 2D / 3D.
+
+
+
+
+
+## Quick Start
+To give the VisualDL a quick test, please use the following commands.
+
+```
+# Install the VisualDL. Preferably under a virtual environment or anaconda.
+pip install --upgrade visualdl
+
+# run a demo, vdl_create_scratch_log will create logs for testing.
+vdl_create_scratch_log
+visualdl --logdir=scratch_log --port=8080
+
+# visit http://127.0.0.1:8080
+```
+
+If you encounter the error `TypeError: __init__() got an unexpected keyword argument 'file'`, that is due to protobuf version is not 3.5+，simply run `pip install --upgrade protobuf` will fix the issue.
+
+If you run into any other issues in above steps, it could be error caused by environmental issues by different python or pip versions.
+Following installation methods might fix the issues.
+
+## Install with Virtualenv
+
+[Virtualenv](https://virtualenv.pypa.io/en/stable/) creates isolated Python environment that prevents interfering
+by other Python programs on the same machine and make sure Python and pip are located properly.
+
+On macOS, install pip and virtualenv by:
+```
+sudo easy_install pip
+pip install --upgrade virtualenv
+```
+
+On Linux, install pip and virtualenv by:
+```
+sudo apt-get install python3-pip python3-dev python-virtualenv
+```
+
+Then create a Virtualenv environment by one of following command:
+```
+virtualenv ~/vdl # for Python2.7
+virtualenv -p python3 ~/vdl for Python 3.x
+```
+
+```~/vdl``` will be your Virtualenv directory, you may choose to install anywhere.
+
+Activate your Virtualenv environment by:
+```
+source ~/vdl/bin/activate
+```
+
+Now you should be able to install VisualDL and run our demo:
+
+```
+pip install --upgrade visualdl
+
+# run a demo, vdl_create_scratch_log will create logs for testing.
+vdl_create_scratch_log
+visualdl --logdir=scratch_log --port=8080
+
+# visit http://127.0.0.1:8080
+```
+
+If you still have issues installing VisualDL from Virtualenv, try following installation method.
+
+
+## Install with Anaconda
+
+Anaconda is a python distribution, with installation and package management tools. Also it is an environment manager,
+which provides the facility to create different python environments, each with their own settings.
+
+Follow the instructions on the [Anaconda download site](https://www.anaconda.com/download) to download and install Anaconda.
+Download Python 3.6 version command-Line installer.
+
+Create a conda environment named ```vdl``` or anything you want by:
+```
+conda create -n vdl pip python=2.7 # or python=3.3, etc.
+```
+
+Activate the conda environment by:
+```
+source activate vdl
+```
+
+Now you should be able to install VisualDL and run our demo:
+
+```
+pip install --upgrade visualdl
+
+# run a demo, vdl_create_scratch_log will create logs for testing.
+vdl_create_scratch_log
+visualdl --logdir=scratch_log --port=8080
+
+# visit http://127.0.0.1:8080
+```
+
+If you still have issues installing VisualDL, try installing from sources as in following section.
+
+
+### Install from source
+```
+#Preferably under a virtualenv or anaconda.
+git clone https://github.com/PaddlePaddle/VisualDL.git
+cd VisualDL
+
+python setup.py bdist_wheel
+pip install --upgrade dist/visualdl-*.whl
+```
+
+If there are still issues regarding the ```pip install```, you can still start Visual DL by starting the dev server
+[here](https://github.com/PaddlePaddle/VisualDL/blob/develop/docs/how_to_dev_frontend_en.md)
+
+
+## SDK
+VisualDL provides both Python SDK and C++ SDK in order to fit more use cases.
+
+
+### Python SDK
+VisualDL now supports both Python 2 and Python 3.
+Below is an example of creating a simple Scalar component and inserting data from different timestamps:
+
+```python
+import random
+from visualdl import LogWriter
+
+logdir = "./tmp"
+logger = LogWriter(logdir, sync_cycle=10000)
+
+# mark the components with 'train' label.
+with logger.mode("train"):
+ # create a scalar component called 'scalars/scalar0'
+ scalar0 = logger.scalar("scalars/scalar0")
+
+# add some records during DL model running.
+for step in range(100):
+ scalar0.add_record(step, random.random())
+```
+
+### C++ SDK
+Here is the C++ SDK identical to the Python SDK example above:
+
+```c++
+#include
+#include
+#include "visualdl/logic/sdk.h"
+
+namespace vs = visualdl;
+namespace cp = visualdl::components;
+
+int main() {
+ const std::string dir = "./tmp";
+ vs::LogWriter logger(dir, 10000);
+
+ logger.SetMode("train");
+ auto tablet = logger.AddTablet("scalars/scalar0");
+
+ cp::Scalar scalar0(tablet);
+
+ for (int step = 0; step < 1000; step++) {
+ float v = (float)std::rand() / RAND_MAX;
+ scalar0.AddRecord(step, v);
+ }
+
+ return 0;
+}
+```
+
+## Launch Visual DL
+After some logs have been generated during training, users can launch Visual DL application to see real-time data visualization by:
+
+
+```
+visualdl --logdir
+```
+
+visualDL also supports following optional parameters:
+
+- `--host` set IP
+- `--port` set port
+- `-m / --model_pb` specify ONNX format for model file to view graph
