python3 -m pip install -r requirements.txt fails

[KansaiTraining]

I tried to do

python3 -m pip install -r requirements.txt but it failed in the third requirement

So I tried what you wrote in your readme

pip3 install --user cython

and installed it without problems. So I tried again

>python3 -m pip install -r requirements.txt

and it stops there.

I can see it is using cached values. What can I do to install the necessary requirements?

@KansaiTraining Thank you for your contact. Did you have any error message on the pycuda installation? As far as I remember, the pycuda installation takes long time (about 30 min).

My apologies. In the end it finished but it really took a long time

@KansaiTraining Thank you for your reply. What a relief!
