使用AIstudio来运行OCR手写模型，运行如下的脚本，会报错

[tlishi]

如题，我在官方AIstudio上运行OCR的脚本!python tools/eval.py -c configs/rec/PP-OCRv3/ch_PP-OCRv3_rec_distillation.yml -o Global.pretrained_model="./pretrained_models/ch_PP-OCRv3_rec_train/best_accuracy"，或者tools/train.py脚本会出现如下报错

ModuleNotFoundError: No module named 'skimage'

ModuleNotFoundError: No module named 'albumentations'

一一通过在线终端安装库之后，最终报出如下错误：

cv._registerMatType(Mat)
AttributeError: module 'cv2' has no attribute '_registerMatType'

我不知道除了修改源代码外还可以通过终端怎么修改？
又或者是官方的脚本内需要更新？
请求帮助我🙏🙏🙏

你在AIstudio上运行OCR手写模型时遇到的错误可以分为几个部分来解决：

1. ModuleNotFoundError: No module named 'skimage' 和 ModuleNotFoundError: No module named 'albumentations'

这些错误是由于缺少必要的Python库导致的。你可以通过以下命令在终端中安装这些库：

!pip install scikit-image albumentations

2. cv._registerMatType(Mat) AttributeError: module 'cv2' has no attribute '_registerMatType'

这个错误通常与OpenCV的版本不兼容有关。你可以尝试升级或降级OpenCV的版本来解决这个问题。建议你尝试以下命令：

!pip install --upgrade opencv-python

如果升级后问题仍然存在，可以尝试降级到特定版本，例如：

!pip install opencv-python==4.5.5.64

3. RuntimeError: cudnnGetConvolutionForwardAlgorithm not found

这个错误通常与CUDA和cuDNN的版本不兼容有关。你可以尝试以下步骤来解决：

1. 检查CUDA和cuDNN的版本：确保你安装的CUDA和cuDNN版本与PaddlePaddle兼容。你可以通过以下命令检查CUDA和cuDNN的版本：

   nvcc --version
   cat /usr/local/cuda/include/cudnn_version.h | grep CUDNN_MAJOR -A 2

2. 重新安装PaddlePaddle：确保你安装的PaddlePaddle版本与CUDA和cuDNN版本兼容。你可以参考PaddlePaddle官方文档选择合适的版本进行安装。例如：

   !pip install paddlepaddle-gpu==2.4.2.post112 -f https://www.paddlepaddle.org.cn/whl/stable.html

3. 禁用MKLDNN：如果你不需要使用MKLDNN加速，可以尝试禁用MKLDNN。在你的脚本中，将enable_mkldnn=True改为enable_mkldnn=False。

总结

1. 安装缺失的库：scikit-image 和 albumentations。
2. 更新或降级OpenCV版本。
3. 检查并确保CUDA和cuDNN版本与PaddlePaddle兼容，必要时重新安装PaddlePaddle。
4. 如果不需要MKLDNN加速，可以尝试禁用MKLDNN。

通过这些步骤，你应该能够解决在AIstudio上运行OCR手写模型时遇到的问题。如果问题仍然存在，建议参考PaddleOCR的官方文档或GitHub Issues页面获取更多帮助。

import cv2
print(cv2.version)
我试着在线运行该代码，报错也是这个

因此是否是因为在线环境缺少cv库导致的?

安装完依赖后，运行项目的脚本还是出错

这个怎么解决？

先安装pip install scikit-image albumentations这两个包
然后装一下opencv-python-headless这个包试试
