[OpenCV’s color image segmentation technology based on HSV space reports an error: ValueError: the input array must be have a shape =]= (.., ..,[ ..,]
Article directory summary Image segmentation concept Segment blue target Split yellow target Split orange target Split green target summary Summary Whenever you see an image, it is usually made up of various elements and objects. In some cases, you may want to extract a specific object from an image. What do you do? The first […]
Solve ValueError: Shape of passed values is (33, 1), indices imply (33, 2)
Table of Contents Solve ValueError: Shape of passed values is (33, 1), indices imply (33, 2) Reason for error Solution 1. Check the dimensions of the data 2. Check index usage 3. Check data type Sample code Solve ValueError: Shape of passed values is (33, 1), indices imply (33, 2) When using Python for data […]
Solving ValueError: y should be a 1d array, got an array of shape (110000, 3) instead.
Table of Contents Solve the problem ValueError: y should be a 1d array, got an array of shape (110000, 3) instead. wrong reason Solution 1. Convert multidimensional target variables into one dimension 2. Modify the model to adapt to multi-dimensional target variables in conclusion Sample Code: Stock Price Prediction Solve ValueError: y should be a […]
PyTorch Tensor Shape
View tensor shape There are two ways to view the tensor shape: View Tensor.shape via properties View Tensor.size() by method The result of both methods is an object of type torch.Size (a subclass of tuple) >>> t = torch.empty(3, 4) >>>t.size() torch.Size([3, 4]) # Get the size of dim=1 dimension >>>t.size(dim=1) 4 >>> t.shape torch.Size([3, […]
Numpy and string formatting, use * to draw the shape of the field
Numpy’s character element matrix can be easily drawn; directly tearing Python strings by hand can also be completed easily. (This note is suitable for coders who are familiar with loops and lists) [The details of learning are a joyful process] Python official website: python cutting edge. Unfortunately it’s the original English version. So, I want […]
Reconstruct the physical Entity architecture to support more shapes
The previous section showed how to compile the BEPUphysicsint source code into your own project and how to integrate the physics engine and Unity graphics rendering. This section will re-adjust the design to separate the basic operations of physical entities from physical shapes, support more physical shapes, and support the synchronization of displacement and rotation […]

Table of Contents Solving ValueError: Cannot feed value of shape (1, 10, 4) for Tensor Placeholder:0 , which has shape Problem background Solution steps 1. Check the shape of your data 2. Adjust the shape of the data 3. Check the model definition 4. Rerun the program Summarize Sample code Introduction to Placeholder tensor Solve […]
ESDA in PySal (4): shape-measures: shape measurements
ESDA in PySal (4): shape-measures: shape measurements 1.Measures of shape The esda.shape module provides statistics used in the literature to measure the structure and regularity of polygons. These measurements range from the very simple, such as length-width difference, to the very complex, such as normalized moment of inertia. Anyway, we’re going to go over step […]
EChartsCustomized shape of dashboard pointer
Here I change the pointer to a sector chart, as follows Mainly through the following code to implement custom-shaped pointers: var option = { series: [ { pointer: { icon: ‘image://data:image/png;base64,iVBORw0KGgoAAAANSU…’, }, } ] }; The complete code is as follows: var chartDom = document.getElementById(‘myChart’); var myChart = echarts.init(chartDom); var option = { animation: false, […]
