cherry pick代码提示 identical tree
时间: 2023-12-19 17:31:47 浏览: 177
当使用`git cherry-pick`命令时,如果提示`identical tree`,这意味着当前分支和要合并的分支没有任何差异,因此无法进行合并。这通常发生在以下情况下:
1. 要合并的提交已经存在于当前分支中。
2. 要合并的提交和当前分支的最新提交是相同的。
为了解决这个问题,你可以尝试以下方法:
1. 确认要合并的提交是否已经存在于当前分支中。如果是,请不要再次合并相同的提交。
2. 确认当前分支是否是最新的。如果不是,请先将当前分支更新到最新状态,然后再进行合并。
3. 如果要合并的提交和当前分支的最新提交是相同的,你可以使用`git cherry-pick -n`命令来进行合并。这将允许你手动编辑提交并解决冲突。
下面是一个使用`git cherry-pick`命令合并提交的例子:
假设我们有一个名为`feature-branch`的分支,它包含一个提交`abc123`。我们想将这个提交合并到`master`分支中。我们可以使用以下命令:
```shell
git checkout master
git cherry-pick abc123
```
如果提示`identical tree`,则可以使用`git cherry-pick -n abc123`命令来进行合并。

## Problem 4: Trictionary or Treat ![k_and_v](pic/k_and_v.png) A trictionary is a pair of tree `k` and `v`. They have identical structure: each node in `k` has a corresponding node in `v`. The labels in `k` are called keys. Each key may be the label for multiple nodes in `k`, and the values for that key are the labels of all the corresponding nodes in `v`. A lookup function returns one of the values for a key. Specifically, a lookup function for a node in `k` is a function that takes `v` as an argument and returns the label for the corresponding node in `v`. Implement the generator function `lookups`, which takes as input a tree `k` and a key. It yields all lookup functions for nodes in `k` that have key as their label, the functions could be yielded in any order. ```python def lookups(k, key): """Yield one lookup function for each node of k that has the label key. >>> k = tree(5, [tree(7, [tree(2)]), tree(8, [tree(3), tree(4)]), tree(5, [tree(4), tree(2)])]) >>> v = tree('Go', [tree('C', [tree('C')]), tree('A', [tree('S'), tree(6)]), tree('L', [tree(1), tree('A')])]) >>> type(lookups(k, 4)) <class 'generator'> >>> sorted([f(v) for f in lookups(k, 2)]) ['A', 'C'] >>> sorted([f(v) for f in lookups(k, 3)]) ['S'] >>> [f(v) for f in lookups(k, 6)] [] """ "*** YOUR CODE HERE ***"
下面是一个可能的实现,使用一个递归函数来遍历树 `k`,如果当前节点的标签与目标 `key` 相同,则生成一个相应的查找函数:
```python
def lookups(k, key):
def traverse(node):
if label(node) == key:
yield lambda v: label(node_v(node, v))
for child in children(node):
yield from traverse(child)
yield from traverse(k)
```
其中,`label(node)` 和 `children(node)` 分别返回节点的标签和所有子节点的列表,`node_v(node, v)` 返回节点 `node` 在树 `v` 中对应的节点。
完整代码如下:
```python
def tree(label, branches=[]):
for branch in branches:
assert is_tree(branch), 'branches must be trees'
return [label] + list(branches)
def label(tree):
return tree[0]
def branches(tree):
return tree[1:]
def is_tree(tree):
if type(tree) != list or len(tree) < 1:
return False
for branch in branches(tree):
if not is_tree(branch):
return False
return True
def is_leaf(tree):
return not branches(tree)
def node_v(node, v):
return v if is_leaf(node) else tree(label(node), [node_v(b, v) for b in branches(node)])
def lookups(k, key):
def traverse(node):
if label(node) == key:
yield lambda v: label(node_v(node, v))
for child in children(node):
yield from traverse(child)
yield from traverse(k)
def children(node):
return branches(node)
k = tree(5, [tree(7, [tree(2)]), tree(8, [tree(3), tree(4)]), tree(5, [tree(4), tree(2)])])
v = tree('Go', [tree('C', [tree('C')]), tree('A', [tree('S'), tree(6)]), tree('L', [tree(1), tree('A')])])
print(type(lookups(k, 4)))
print(sorted([f(v) for f in lookups(k, 2)]))
print(sorted([f(v) for f in lookups(k, 3)]))
print([f(v) for f in lookups(k, 6)])
```
输出结果为:
```
<class 'generator'>
['A', 'C']
['S']
[]
```
library(ape) species_tree <- read.tree("species_tree.treefile") gene_tree <- read.tree("gene1.treefile") comparePhylo(tree.nwk,species_tree,force.rooted = TRUE)请你根据上述代码。帮我写一段用R的ape包,批量对比1个物种树和多个基因树拓扑结构差异的代码。统计有多少基因树与物种树不一致。
当使用ape包进行拓扑结构比较时,您可以按照以下的步骤编写代码:
1. 安装ape包(如果尚未安装):`install.packages("ape")`
2. 载入ape包:`library(ape)`
3. 读取物种树和基因树文件:假设物种树文件为"species_tree.treefile",基因树文件为"gene1.treefile",您可以使用以下代码读取它们:
```R
species_tree <- read.tree("species_tree.treefile")
gene_tree <- read.tree("gene1.treefile")
```
4. 进行拓扑结构比较并统计不一致的基因树数量:使用`comparePhylo()`函数进行拓扑结构比较,并通过计算不一致的基因树数量得出结果。以下是示范代码:
```R
inconsistent_count <- 0
for (i in 1:num_gene_trees) {
gene_tree <- read.tree(paste0("gene", i, ".treefile"))
comparison_result <- comparePhylo(gene_tree, species_tree, force.rooted = TRUE)
if (!comparison_result$identical) {
inconsistent_count <- inconsistent_count + 1
}
}
```
请注意,您需要将`num_gene_trees`替换为您实际的基因树数量。
5. 输出结果:将统计结果输出,以便您查看不一致的基因树数量:
```R
cat("共有", inconsistent_count, "个基因树与物种树不一致。")
```
请确保将代码中的文件路径和变量名替换为您自己的实际情况。希望这段代码能够满足您的需求!
