+# Q: What if I can 'pip install' visualdl but cannot find the module while running it?
+A: It could be due to the mismatch of the locations from 'python' and 'pip'. For example, a user could install visualdl here:
+
+`[develop]$ pip show visualdl
+Name: visualdl
+Version: 1.0.0
+Summary: Visualize Deep Learning
+Home-page: UNKNOWN
+Author: PaddlePaddle and Echarts team
+Author-email: UNKNOWN
+License: Apache License
+Location: /usr/local/lib/python2.7/site-packages
+Requires: Flask, Pillow, numpy, protobuf, scipy`
+
+But his/her python is actually here:
+
+`
+[develop]$ which python
+/Library/Frameworks/Python.framework/Versions/2.7/bin/python
+`
+So when running visualdl, the system would look for the visualdl command in `2.7/lib/python2.7/site-packages/`
+
+One hacky solution is to simply copy the installed files at the pip location to the python location:
+
+`cp -r /usr/local/lib/python2.7/site-packages/visualdl /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/`
+
