问题 I'm trying plot my model on the google colab. from keras.utils import plot_model plot_model(model, to_file="model.png") and I got this error: ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work. I've installed pydot-ng and graphviz and I'm still can't get through this error. 回答1: To install pydot , run: !pip install -q pydot Then, restart your VM to reload keras which should then detect pydot's existence.

问题 cap = cv2.VideoCapture(0) is not opening web camera when executing the command in Google Colab. 回答1: Since Colab is running in your browser, you'll want to use web APIs to access local hardware like a camera.

Meaning of “Power Level” on google colab

最后都变了- 提交于 2019-11-30 10:59:55
When I open a new notebook on Goole Colab I see a "POWER LEVEL" indicator with a battery symbol at the top. I can click it and choose three different power levels: low, medium and high. I don't remember ever seeing this before on Google Colab. I believe this is a new undocumented feature. Does anybody know what is the effect of changing power levels? Power level is an April fools joke feature that adds sparks and combos to cell editing -- https://twitter.com/GoogleColab/status/1112708634905964545 来源: https://stackoverflow.com/questions/55458800/meaning-of-power-level-on-google-colab
