PIL在我的系统中支持JPEG.

每当我上传时,我的代码都失败了:

File "PIL/Image.py", line 375, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

我该如何解决这个问题？

我正在尝试使用pip安装Pillow(Python模块),但它会抛出此错误:

ValueError: jpeg is required unless explicitly disabled using --disable-jpeg, aborting

所以当错误说,我试过:

pip install pillow --global-option="--disable-jpeg"

但它失败了:

error: option --disable-jpeg not recognized

任何提示如何处理它？

我有一个需要PIL运行的脚本.除了降级我的Python,我无论如何都找不到在我的Python 3.6上安装PIL

以下是我的尝试:

pip install pil
Collecting pil
  Could not find a version that satisfies the requirement pil (from versions: )

pip install Pillow

我正在尝试调整一些图像的大小,其中大部分都是JPG.但在一些图像中,我收到错误:

Traceback (most recent call last):
  File "image_operation_new.py", line 168, in modifyImage
    tempImage.save(finalName);
  File "/Users/kshitiz/.virtualenvs/django_project/lib/python2.7/site-     packages/PIL/Image.py", line 1465, in save

    raise IOError("cannot write mode %s as JPEG" % im.mode)
IOError: cannot write mode P as JPEG

我没有改变图像类型,我正在使用枕头库.我的操作系统是Mac OS X.我该如何解决这个问题？

我正在尝试使用此命令在Ubuntu 14.04上安装Pillow:

pip install Pillow

但安装失败并出现此错误:

ValueError: --enable-jpeg requested but jpeg not found, aborting.

我不熟悉PIL,但我知道将一堆图像放入ImageMagick的网格中非常容易.

例如,我如何将16个图像放入4×4网格中,我可以指定行和列之间的间隙？

我有一个ec2实例,最初在我的virtualenv中安装了Pillow 2.0.不知何故,当我尝试将其升级到Pillow 2.5时,它失败并显示以下消息.即使我在重新安装之前完全移除了Pillow,错误也是一样的.(所以现在我的枕头根本没有Pillow)

我正在做一个关于udacity的深入学习课程.对于第一次分配,当我试图运行低于问题1的脚本时,我收到了这个错误.所以我试图卸载PIL和枕头,然后单独安装,但我没有成功.我需要帮助的人.我正在使用与python笔记本的tensorflow docker图像.

我在Flask中创建了一个简单的API,它接受在base64中编码的图像,然后将其解码以便使用Pillow进行进一步处理.

我看了一些例子(1,2,3),我觉得我得到的过程的要点,但我不断收到一个错误的枕头无法读取我给它的字符串.

这是我到目前为止所得到的:

import cStringIO
from PIL import Image
import base64

data = request.form
image_string = cStringIO.StringIO(base64.b64decode(data['img']))
image = Image.open(image_string)

这给出了错误:

IOError: cannot identify image file <cStringIO.StringIO object at 0x10f84c7a0>

我有这个大小为128 x 128像素的图像,RGBA作为字节值存储在我的内存中.但

from PIL import Image

image_data = ... # byte values of the image
image = Image.frombytes('RGBA', (128,128), image_data)
image.show()

抛出异常

ValueError:没有足够的图像数据

为什么？我究竟做错了什么？
