Error: when trying to plot the graph: from PyQt5.QtWidgets import * ImportError: No module named PyQt5.QtWidgets #4

Hi, I was able to install the machine-learning package, run gazebo and start dqn. However, when I tried to plot the graph using "roslaunch turtlebot3_dqn result_graph.launch", I got errors and will not be able to view the graphs. logs: catkin_ws/src/turtlebot3_machine_learning/turtlebot3_dqn/nodes/action_graph", line 21, in from PyQt5.QtWidgets import ImportError: No module named PyQt5.QtWidgets /catkin_ws/src/turtlebot3_machine_learning/turtlebot3_dqn/nodes/result_graph", line 23, in from PyQt5.QtGui import ImportError: No module named PyQt5.QtGui

I was thinking about the mismatch between pyqt4 and pyqt5 so I installed pyqt5 but there is no change. Also I tried to change import PyQt5. in action_graph/result_graph files to import PyQt4. but not effective.

I noticed in the tutorial it install pyqt 4.11.4.

May I know what's going on and how to solve it?

Thanks, BowenY

Hi @BowenY :) Maybe this will solve your problem.

pip uninstall tensorflow
pip install tensorflow==1.5
pip install keras
pip install pyqtgraph

Thanks, Gilbert.

Hi Gilbert, I too had similar issue...I tried the fix that you had recommended..but its doesn't resolve the issue. The same error is reported.

Thanks Vincent

Hi @Vincent7803 :) Could you remove anaconda2 folder? and then make a new anaconda2 folder bash Anaconda2-5.2.0-Linux-x86_64.sh

Try again command I said.

Thanks.

It works now. Thanks Gilbert

BowenY commented 6 years ago

Hi @kijongGil It worked perfectly, thanks!

P.S. I also need to re-install the ros dependency packages using "pip install -U rosinstall msgpack empy defusedxml netifaces" after I re-installed anaconda, tensorflow, kersa and pyqtgraph to use gazebo. I dont know if Vincent7803 encountered the same requirement but I would love to note this for anyone else may have this situation.
