Basic BigARTM tutorial for Windows users¶
This tutorial gives guidelines for installing and running existing BigARTM examples via command-line interface and from Python environment.
The distribution will contain pre-build binaries, command-line interface and BigARTM API for Python. The distribution also contains a simple dataset and few python examples that we will be running in this tutorial. More datasets in BigARTM-compatible format are available in the Downloads section.
Refer to Windows distribution for details about other files, included in the binary distribution package.
Running BigARTM from command line¶
No installation steps are required to run BigARTM from command line.
After unpacking binary distribution simply open command prompt (
change current directory to
bin folder inside BigARTM package, and run
cpp_client.exe application as in the following example.
As an optional step, we recommend to add
bin folder of the BigARTM distribution to your
PATH system variable.
>C:\BigARTM\bin>set PATH=%PATH%;C:\BigARTM\bin >C:\BigARTM\bin>cpp_client.exe -v ../python/examples/vocab.kos.txt -d ../python/examples/docword.kos.txt -t 4 Parsing text collection... OK. Iteration 1 took 197 milliseconds.

We recommend to download larger datasets, available in Downloads section.
vocab files can be consumed by BigARTM exactly as in the previous example.
Internally BigARTM always parses such files into batches format (for example, enron_1k (7.1 MB)). If you have downloaded such pre-parsed collection, you may feed it into BigARTM as follows:
>C:\BigARTM\bin>cpp_client.exe --batch_folder C:\BigARTM\enron Reuse 40 batches in folder 'enron' Loading dictionary file... OK. Iteration 1 took 2502 milliseconds.
For more information about
cpp_client.exe refer to BigARTM command line utility section.
Configure BigARTM Python API¶
Install Python, for example from the following links:
- Python 2.7.9, 64 bit – https://www.python.org/ftp/python/2.7.9/python-2.7.9.amd64.msi, or
- Python 2.7.9, 32 bit – https://www.python.org/ftp/python/2.7.9/python-2.7.9.msi
Remember that the version of BigARTM package must match your version Python installed on your machine. If you have 32 bit operating system then you must select 32 bit for Python and BigARTM package. If you have 64 bit operating system then you are free to select either version. However, please note that memory usage of 32 bit processes is limited by 2 GB. For this reason we recommend to select 64 bit configurations.
Also you need to have several Python libraries to be installed on your machine:
- numpy >= 1.9.2
- scipy >= 0.15.0
- pandas >= 0.16.2
- scikit-learn >= 0.16.1
C:\BigARTM\binfolder to your
PATHsystem variable, and add
set PATH=%PATH%;C:\BigARTM\bin set PATH=%PATH%;C:\Python27;C:\Python27\Scripts set PYTHONPATH=%PYTHONPATH%;C:\BigARTM\Python
Remember to change
C:\Python27with your local folders.
Setup Google Protocol Buffers library, included in the BigARTM release package.
- Run the following commands from command prompt
cd C:\BigARTM\protobuf\Python python setup.py build python setup.py install
python setup.py teststep, as it produces several confusing errors. Those errors are harmless. For further details about protobuf installation refer to protobuf/python/README.
