python picasso/examples/keras-vgg16/prepare_model.py

from keras.applications.vgg16 import VGG16

ImportError: No module named 'keras'

分析：

如果是已經安裝了keras之後還出現上面bug，很有可能是start了python2的。python2.x和python3.x出現了混亂。

python3 picasso/examples/keras-vgg16/prepare_model.py

二、ValueError: unknown locale: UTF-8

File "/Users/wyl/Documents/effectmatrix/program/minetest/MCEdit-Unified-master/ENV/lib/python2.7/locale.py", line 545, in getdefaultlocale

    return _parse_localename(localename)

  File "/Users/wyl/Documents/effectmatrix/program/minetest/MCEdit-Unified-master/ENV/lib/python2.7/locale.py", line 477, in _parse_localename

    raise ValueError, 'unknown locale: %s' % localename

ValueError: unknown locale: UTF-8

解決方法：

1.在.bash_profile檔案中加入 

export LANG="en_US.UTF-8"

export LC_COLLATE="en_US.UTF-8"

export LC_CTYPE="en_US.UTF-8"

export LC_MESSAGES="en_US.UTF-8"

export LC_MONETARY="en_US.UTF-8"

export LC_NUMERIC="en_US.UTF-8"

export LC_TIME="en_US.UTF-8"

2.source 使用更新後的內容

source .bash_profile

測試

python -c 'import locale; print(locale.getdefaultlocale());'
