"## Perform Training on a Toy Dataset with MMOCR Recognizer\n",
"We now demonstrate how to perform training with an MMOCR recognizer. Since training a full academic dataset is time consuming (usually takes about several hours), we will train on the toy dataset for the SAR text recognition model and visualize the predictions. Text detection and other downstream tasks such as KIE follow similar procedures.\n",
"\n",
"Training a dataset usually consists of the following steps:\n",
"1. Convert the dataset into a format supported by MMOCR (e.g. COCO for text detection). The annotation file can be in either .txt or .lmdb format, depending on the size of the dataset. This step is usually applicable to customized datasets, since the datasets and annotation files we provide are already in supported formats. \n",
"2. Modify the config for training. \n",
"3. Train the model. \n",
"\n",
2021-08-25 11:45:47 +08:00
"The toy dataset consisits of ten images as well as annotation files in both txt and lmdb format, which can be found in [ocr_toy_dataset](https://github.com/open-mmlab/mmocr/tree/main/tests/data/toy_dataset). "
