I've tried to do on Windows Terminal and faced the same error. I did install the python-pydot, pynot--ng, and graphviz but it wouldn't help me to solve this issue.

I am really new to everything, just installed Docker and WSL.. So it would be great if you can give de some guidance in detail, please.

It appears that you are working with python3, so you should install the python3 versions of pydot and pydot-ng: the already requested python3-pydot and the python3-pydot-ng package.

QUESTION

Running valgrind after restoring from a gem5 checkpoint

Asked 2022-Mar-16 at 13:30

We are working on a project in gem5, and suspect that there exists a memory leakage in a new memory object that we have implemented. Typically, this is easy enough... launch a compiled gem5.debug binary with valgrind --leak-check=full. Unfortunately, this memory object doesn't do anything of consequence until the memory mode switches from Atomic to Timing (i.e., after fast forwarding and restoring from a checkpoint with a different CPU model).

When we run the command: valgrind --leak-check=full --log-file=valgrind-out.txt --track-orgins=yes build//gem5.debug -d /path/to/outdir /path/to/python/config.py --checkpoint-restore=1 --other-options...

We get the following output (which occurs after many of the gem5 objects have been created):

...

ANSWER

Answered 2022-Mar-16 at 13:30

From How does valgrind work?, valgrind pre-processes and modifies the application before it is run. This would mean that valgrind expects certain pre-allocated pointers in certain locations. Furthermore, when looking at the valgrind output, you may see the following: Warning: set address range perms: large range [start, end) (undefined). It is likely the case that large gem5 objects have overwritten valgrind metadata to corrupt existing pointers, which would result in a bus error.

For future reference, we successfully used LibLeak, which has very clear documentation, is easy to use with gem5, and really low runtime overhead. It also helped us successfully find the memory leak :-)

After trying for a few days and just found out that pip and python in the project are not pointing to .venv but to anaconda due to an update. when error

no module stdnum

actually there is a problem with pip so make sure your pip path with which pip or which python

to solve .venv that doesn't work by deleting the .venv folder, create venv in python, and install all requirements again

Trouble installing ROS Melodic Ubuntu 21.10

Asked 2021-Dec-12 at 22:41

I am trying to install ROS Melodic using the instructions on wiki.ros.org and stumbled upon some problems.

System software information:

Operating System: Kubuntu 21.10

KDE Plasma Version: 5.22.5

KDE Frameworks Version: 5.86.0

Qt Version: 5.15.2

ANSWER

Answered 2021-Dec-12 at 22:41

You're getting this error because Melodic is the ros distro for Ubuntu 18.04. As of present the most recent release is Noetic which targets 20.04. The version of Ubuntu you're using does not currently have a supported ROS release, as such your only real option is to downgrade if you want ROS.

Keras image classification val_accuracy doesn't improve

Asked 2021-Dec-11 at 20:55

I tried to basically copy this tutorial: https://keras.io/examples/vision/image_classification_from_scratch/

But I can't seem to improve on my val_accuracy score. I also have 2 kinds of images dogs (Hunde) and cats (Katzen) but only 95 samples each. I have an "upper" folder "Hunde und Katzen" where the folders of these samples are. I probably have to tune some parameters, because my sample size is so low but I already tried at some code parts.

...

ANSWER

Answered 2021-Dec-11 at 13:24

95 samples for each class is less to achieve a decent accuracy

decrease your validation_split to 0.05 (5% for validation ), as you have very less number of data points
If the first step does not help you then you can use transfer learning i.e using architectures that have a good accuracy on imagenet for e.g: MobileNets, ResNets and efficientnets
If the above 2 steps are not giving you a good accuracy then try increasing your data size and tune your hyperparameters.

ANSWER

Answered 2021-Dec-10 at 16:03

In the thread you linked, there are several solutions, and an interesting one seems to be that a package named fitz conflicts with PyMuPDF, as they both use the same top name inside a script (being fitz). I see both libraries are in your requirements.txt, so this could be the cause of this error. I tested adding both libraries inside a Cloud Function and received the same error, which was resolved after removing fitz 0.0.1.dev2 from the file, and using only PyMuPDF.

You can see another example of this behavior from this GitHub issue.
