Pydotplus Suganya Karunamurthy, Install Pydotplus | Machine Learning, May 6, 2020, https://m.youtube.com/watch?v=FyFRRPmZgfI, accessed November 29, 2020.
Subj.: InvocationException: GraphViz's executables not found
Ms Sugary Karunamurthy replied my post at https://www.youtube.com/watch?v=FyFRRPmZgfI on December 3, 2020, encouraging me to install pydotplus from Jupyter notebook using the command !pip install pydotplus
. This command feeds out that "Requirement already satisfied: pydotplus in /Users/(MyName)/opt/anaconda3/lib/python3.8/site-packages (2.0.2) Requirement already satisfied: pyparsing>=2.0.1 in /Users/(MyName)/opt/anaconda3/lib/python3.8/site-packages (from pydotplus) (2.4.7) Note: you may need to restart the kernel to use updated packages." I am so happy, but unfortunately, the test of decision tree ends in "GraphViz's executables not found" after testing. My testing codes are taken from https://pythonprogramminglanguage.com/decision-tree-visual-example/, which run as follows:
`import pydotplus from sklearn.datasets import load_iris from sklearn import tree import collections
X = [ [180, 15,0],
[177, 42,0],
[136, 35,1],
[174, 65,0],
[141, 28,1]]
Y = ['man', 'woman', 'woman', 'man', 'woman']
data_feature_names = [ 'height', 'hair length', 'voice pitch' ]
clf = tree.DecisionTreeClassifier() clf = clf.fit(X,Y)
dot_data = tree.export_graphviz(clf, feature_names=data_feature_names, out_file=None, filled=True, rounded=True) graph = pydotplus.graph_from_dot_data(dot_data)
colors = ('turquoise', 'orange') edges = collections.defaultdict(list)
for edge in graph.get_edge_list(): edges[edge.get_source()].append(int(edge.get_destination()))
for edge in edges:
edges[edge].sort()
for i in range(2):
dest = graph.get_node(str(edges[edge][i]))[0]
dest.set_fillcolor(colors[i])
graph.write_png('tree.png')`
As I knew it is an environment problem, so as to search duckduckgo.com for MacOS X solution. It seems that everything is for Windows instead. Thus, this issue is still out of solution till now.
brew install graphviz
in macOS Terminal leads to failure in MacBook Pro (Mid-2009), say, a lot of issues are encountered as follows:The output of macOS Terminal are:

curl: (60) SSL certificate problem: Invalid certificate chain More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. Error: Failed to download resource "git--html"
