Extract text from Doc2Vec models and indexes (D2V)
To convert D2V models and indexes to another format, you need Gensim or other Data software.
To convert other file formats to the "Machine Learning Model" file type, you need software like Gensim or a similar tool.
A .D2V file primarily functions as a trained Doc2Vec machine learning model. It contains multidimensional vector representations of text documents, allowing algorithms to understand semantic similarities between paragraphs or entire articles. A much older, secondary use of the .D2V extension is as a video frame index file created during DVD ripping.
The modern NLP model variant is exclusively created and opened using the Gensim library in Python. The legacy video variant is generated by obsolete software like DVD2AVI or DGIndex to frame-serve MPEG-2 video to AviSynth.
Users often need to convert .D2V files because they want to migrate the trained vectors to another programming language, a database, or a visualization tool. The major disadvantage of the .D2V format is that it relies on Python object serialization (pickling) combined with Gensim's internal structure. It requires a complete, identical Python environment to open. If you upgrade your library, older models frequently break. For the video variant, the file is useless without the original massive VOB video files it points to.
The best conversion targets for a Doc2Vec model are plain text formats like CSV or JSON. Exporting to these formats flattens the multidimensional array, ensuring you keep the raw vector numbers but lose the programmatic methods of the original Python object.
Because a .D2V model is a complex, serialized binary structure, it is highly difficult to open or convert without writing custom code. Standard online converters fail to process it. Only the original software can properly read or export the data. However, you can just drag and drop your file onto convert.guru to identify the format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Use Convert.Guru to open and convert your D2V file.
Users also converted DSW, DRP and MG1 files.
If you want to convert D2V file to MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP, OGV, ASF or RM, you can use Gensim or similar software from the "Trained NLP Model Data" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to D2V, try Gensim or another comparable tool in the "Trained NLP Model Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our D2V converter.
