ModuleNotFoundError：没有名为“skimage”的模块

Question

我已经在以下路径上安装了我的 scikit-image：要求已经满足：scikit-image

我已经通过 PyCharm 的解释器安装了它

但是，每当我运行以下

from skimage import data
from skimage.feature import register_translation
from skimage.feature.register_translation import _upsampled_dft

它不断返回错误如下：

ImportError: No module named skimage

import numpy as np
import matplotlib.pyplot as plt

from skimage import data
from skimage.feature import register_translation
from skimage.feature.register_translation import _upsampled_dft
from scipy.ndimage import fourier_shift

image = data.camera()
shift = (-22.4, 13.32)
# The shift corresponds to the pixel offset relative to the reference image
offset_image = fourier_shift(np.fft.fftn(image), shift)
offset_image = np.fft.ifftn(offset_image)
print("Known offset (y, x): {}".format(shift))

# pixel precision first
shift, error, diffphase = register_translation(image, offset_image)

fig = plt.figure(figsize=(8, 3))
ax1 = plt.subplot(1, 3, 1)
ax2 = plt.subplot(1, 3, 2, sharex=ax1, sharey=ax1)
ax3 = plt.subplot(1, 3, 3)

ax1.imshow(image, cmap='gray')
ax1.set_axis_off()
ax1.set_title('Reference image')

ax2.imshow(offset_image.real, cmap='gray')
ax2.set_axis_off()
ax2.set_title('Offset image')

# Show the output of a cross-correlation to show what the algorithm is
# doing behind the scenes
image_product = np.fft.fft2(image) * np.fft.fft2(offset_image).conj()
cc_image = np.fft.fftshift(np.fft.ifft2(image_product))
ax3.imshow(cc_image.real)
ax3.set_axis_off()
ax3.set_title("Cross-correlation")

plt.show()

这种导入失败的原因是什么？

由于您使用的是 PyCharm，我认为您必须检查是否在您正在使用的同一环境中安装了该软件包。
