How to install numpy 、scikit-image、scikit-learn on Jetson TX2?

After install Jetpack4.2, pyrhon3.6.8、tensoflow==1.14.0、keras==2.3.1, errors occur when running :
Traceback (most recent call last):
File “predict_main.py”, line 2, in
import skimage.io
ModuleNotFoundError: No module named ‘skimage’

So,how to pip3 install skimage(scikit-image=0.15.0).By the way ,how to pip3 inatall the related packages such as numpy 、scikit-learn? Please tell me the correct answer,thank U.

But when i run the simple demo ,some errors still existed
root@tx2:~/Documents# python3 skitest.py
Traceback (most recent call last):
File “skitest.py”, line 1, in
import skimage.transform as st
ModuleNotFoundError: No module named ‘skimage’

and the skitest.py is as follows:
import skimage.transform as st
import numpy as np
import matplotlib.pyplot as plt
#matplotlib inline

构建测试图片

image = np.zeros((100, 100)) #背景图
idx = np.arange(25, 75) #25-74序列
image[idx[::-1], idx] = 255 # 线条
image[idx, idx] = 255 # 线条/

hough线变换

h, theta, d = st.hough_line(image)

#生成一个一行两列的窗口(可显示两张图片).
fig, (ax0, ax1) = plt.subplots(1, 2, figsize=(8, 6))
plt.tight_layout()

#显示原始图片
ax0.imshow(image, plt.cm.gray)
ax0.set_title(‘Input image’)
ax0.set_axis_off()

#显示hough变换所得数据
ax1.imshow(np.log(1 + h))
ax1.set_title(‘Hough transform’)
ax1.set_xlabel(‘Angles (degrees)’)
ax1.set_ylabel(‘Distance (pixels)’)
ax1.axis(‘image’)
plt.show()

SO what should i do ,please tell me.

same problem here, there’s no solution jet?

Hi, martin.chavez

This topic was one year old, and the information is out of date.

For JetPack4.4.1, numpy is preinstalled.
You can also install other libraries with the instructions shared in the below post:

Thanks.
