### Unable to install?
|

-
|
| 202 |
-
The present program needs an AI model(`wybxc/DocLayout-YOLO-DocStructBench-onnx`) before working and some users are not able to download due to network issues. If you have a problem with downloading this model, we provide a workaround using the following environment variable:
|
| 203 |
-
|
| 204 |
-
```shell
|
| 205 |
-
set HF_ENDPOINT=https://hf-mirror.com
|
| 206 |
-
```
|
| 207 |
-
|
| 208 |
-
For PowerShell user:
|
| 209 |
-
|
| 210 |
-
```shell
|
| 211 |
-
$env:HF_ENDPOINT = https://hf-mirror.com
|
| 212 |
-
```
|
| 213 |
-
|
| 214 |
-

Execute the translation command in the command line to generate the translated document `example-mono.pdf` and the bilingual document `example-dual.pdf` in the current working directory. Use Google as the default translation service. More support translation services can find [HERE](https://github.com/Byaidu/PDFMathTranslate/blob/main/docs/ADVANCED.md#services).

-
|
| 253 |
-
The current pdf2zh API is temporarily deprecated. The API will be provided again after [pdf2zh 2.0](https://github.com/Byaidu/PDFMathTranslate/issues/586) is released. For users who need programmatic access, please use the `babeldoc.high_level.async_translate` function of [BabelDOC](https://github.com/funstory-ai/BabelDOC).
|
| 254 |
-
|
| 255 |
-
This API being temporarily deprecated means: the relevant code will not be removed for now, but no technical support will be provided, and no bug fixes will be made.
|
| 256 |

# PDFMathTranslate Docker Space
|
| 11 |
|
| 12 |
+
This Space runs the [PDFMathTranslate](https://github.com/Byaidu/PDFMathTranslate) tool using a Docker container.
|
| 13 |
|
| 14 |
+
It allows translating PDF files, especially those containing mathematical formulas, into Chinese.
|
| 15 |
|
| 16 |
+
The application is started via the `CMD ["pdf2zh", "-i"]` command within the Dockerfile.
