使用unstructured中的表格转换器产生以下警告信息。此问题的目标是清理警告。原始问题描述如下。

Some weights of the model checkpoint at microsoft/table-transformer-structure-recognition were not used when initializing TableTransformerForObjectDetection: ['model.backbone.conv_encoder.model.layer2.0.downsample.1.num_batches_tracked', 'model.backbone.conv_encoder.model.layer3.0.downsample.1.num_batches_tracked', 'model.backbone.conv_encoder.model.layer4.0.downsample.1.num_batches_tracked']
- This IS expected if you are initializing TableTransformerForObjectDetection from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing TableTransformerForObjectDetection from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).

原始问题

描述错误

当我调用partition_pdf时，会出现以下情况：

from unstructured.partition.pdf import partition_pdf
path = "/app/example-docs/"
fname = "list-item-example.pdf"
raw_pdf_documents = partition_pdf(
... filename=path + fname,
... extract_images_in_pdf=False,
... infer_table_structure=True,
... chunking_strategy="by_title",
... max_characters=4000,
... new_after_n_chars=3800,
... combine_text_under_n_chars=2000,
... image_output_dir_path=path,
... )

在microsoft/table-transformer-structure-recognition的模型检查点的一些权重在初始化TableTransformerForObjectDetection时未被使用：['model.backbone.conv_encoder.model.layer2.0.downsample.1.num_batches_tracked', 'model.backbone.conv_encoder.model.layer3.0.downsample.1.num_batches_tracked', 'model.backbone.conv_encoder.model.layer4.0.downsample.1.num_batches_tracked']

• 如果从另一个任务或具有其他架构的模型的检查点初始化TableTransformerForObjectDetection(例如，从BertForPreTraining模型初始化BertForSequenceClassification模型),这是预期的行为。
• 如果从您期望完全相同的模型的检查点初始化TableTransformerForObjectDetection(例如，从BertForSequenceClassification模型初始化BertForSequenceClassification模型),则这不是预期的行为。
  重现

只需运行上面的代码

预期行为

运行partition_pdf时没有错误或警告

截图

如果适用，请添加截图以帮助解释您的问题。

环境信息

在MacPro Intel Core i9上运行的Docker镜像
Docker容器以以下方式启动：
创建容器
docker run -dt --name unstructured downloads.unstructured.io/unstructured-io/unstructured:latest
这将使您进入一个bash shell,其中Docker镜像正在运行
docker exec -it unstructured bash
