NotImplementedError：此传输语法 JPEG 2000 图像压缩，无法读取，因为 Pillow 缺少 jpeg 2000 解码器插件

Question

我正在运行代码以在 Python 中可视化和分析 DICOM 图像。当我运行代码为每个切片位置提取 DICOM 像素并显示单个切片时，我收到以下错误：NotImplementedError: this transfer syntax JPEG 2000 Image Compression, can not be read because Pillow lacks the jpeg 2000 decoder plugin 这是我正在关注的教程的链接：Link to the tutorial

我的代码如下：

# set path and load files 
path = 'C:\\Users\\MyName\\Desktop\\DICOM\\series-00000\\'
patient_dicom = load_scan(path)
patient_pixels = get_pixels_hu(patient_dicom)
#sanity check
plt.imshow(patient_pixels[326], cmap=plt.cm.bone)

错误是：

我安装了所有推荐的包，包括 Pillow，我的 Python 版本是 3.7。 我通过运行以下命令 conda install -c conda-forge openjpeg 通过 anaconda 提示安装了 openJPEG，但仍然给我同样的错误。

我哪里做错了？

Answer 1

似乎某些库和包不适用于 python 3.7 及更高版本。我不得不从我的计算机中完全删除 Anaconda 并重新安装它。然后通过 Anaconda Prompt 降级到 python 3.6.10，因为 Jubyter Notebook 的默认值是 3.7。然后我安装了所需的库和包，但是，它不能与 Jubyter Notebook 一起使用，而是与 JubyterLab 完美配合。
