Question

我已经开始学习Tensorflow。我正在使用Pycharm，我的环境是Ubuntu 16.04。我正在关注tutorial。我交叉检查了小瘤。它是最新的。我不知道此错误的原因。

从numpy.lib.arraypad导入_validate_lengths

ImportError：无法导入名称“ _validate_lengths”

需要提示以解决此错误。谢谢。

#listdir: This method returns a list containing the names of the entries in the directory given by path.

train_data_dir = os.path.join(ROOT_PATH, "TrafficSigns/Training")
test_data_dir = os.path.join(ROOT_PATH, "TrafficSigns/Testing")

images, labels = load_data(train_data_dir)

# Print the `images` dimensions
print(images.ndim)

# Print the number of `images`'s elements
print(images.size)

# Print the first instance of `images`
images[0]

Answer 1

I updated my skimage package.

pip install --upgrade scikit-image

And the problem was solved. It's a problem of version of Skimage, which is solved in 0.14.2. PLus, this version is quite stable.

    Installing collected packages: dask, scikit-image
  Found existing installation: dask 0.19.1
    Uninstalling dask-0.19.1:
      Successfully uninstalled dask-0.19.1
  Found existing installation: scikit-image 0.13.0
    Uninstalling scikit-image-0.13.0:
      Successfully uninstalled scikit-image-0.13.0
Successfully installed dask-1.0.0 scikit-image-0.14.2

Answer 2

pip install scikit-image==0.14.2 && pip install numpy==1.15

参考：Here

Answer 3

scikit-image 0.14.2与numpy 1.16.3一起使用。我先安装了numpy，然后安装了scikit映像

Answer 4

我有同样的错误，我执行了以下步骤：

卸载scikit映像

pip uninstall scikit-image

或

conda uninstall scikit-image

然后

pip install scikit-image

或

conda install -c conda-forge scikit-image

Answer 5

对我来说，魔术依赖是：

pip install scikit-image==0.13.1
pip install numpy==1.15

对于python 3.5和python 3.6

Answer 6

将scikit映像升级到最新版本，或者将NumPy降级为1.15。

https://github.com/pyinstaller/pyinstaller/archive/develop.zip

或

 pip install -U scikit-image

如果该点不是最新的。您可能需要这个：

 pip install numpy==1.15

请参阅Getting ImportError: cannot import name '_validate_lengths' #3906。

Answer 7

由于两个版本同时安装，我似乎也遇到了相同的问题。

我通过多次卸载scikit-image直到没有任何问题来解决了这个问题。

pip uninstall scikit-image

然后重新安装：

pip uninstall scikit-image

对我有用。
