The error Backend should be defined in the BACKENDS_MAPPING. Offending backend: tensorflow_text indicates that the tensorflow_text library—a dependency required by the faster‑whisper backend—is missing or not properly registered in your environment.

Root Cause
The packaged sp.exe expects tensorflow_text to be present. If you're using the full green package (2.6GB+), this component is included; if you accidentally downloaded only the patch package (~260MB), the required dependencies are incomplete.

Solution

Ensure you have the full package – Download the complete 2.6GB win-pyvideotrans-v4.05-0711.7z from the official site, extract it fully, and then do not overwrite with the patch unless you already have the full base.
Re‑extract to a simple, short path – Move the extracted folder to a location with only English letters, digits, and underscores (e.g., D:\pyVideoTrans). Avoid long file names, spaces, and special characters — your current video path contains many dots, spaces, and a long name, which can also trigger ffmpeg/whisper issues.
Run as administrator once – Right‑click sp.exe → "Run as administrator" to ensure all dependencies load correctly.
Verify CUDA/GPU is NOT required – The error occurs even without CUDA, but if you have an NVIDIA GPU, make sure CUDA 12.8+ and cuDNN 9.11+ are installed. The log shows is_cuda=False, so CUDA is not the cause here.

If the problem persists after following the steps above, please provide the contents of the latest log file from logs/ (the file ending with .log for today’s date) so we can investigate further.
