Unable to use monai in google colab

[toufiqmusah]

I'm unable to properly pip install, and then import monai in google colab. This started few days ago after some updates to the colab environment and seems to be associated with numpy.

Running pip install monai will install successfully but with the following error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
thinc 8.3.6 requires numpy<3.0.0,>=2.0.0, but you have numpy 1.26.4 which is incompatible.

And then importing anything monai throws the following:
ValueError Traceback (most recent call last)

ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

I have so far tried downgrading/upgrading numpy with no success.

It appears that thinc’s 8.3.6 release made Numpy 2 required however a previous release was Numpy 1 and 2 compatible. This likely was a mistake by the developer. See explosion/thinc#954 (comment).

We will be supporting Numpy 2 with the upcoming 1.5 release, in the meantime you can install monai-weekly to use the current weekly snapshot.

Thanks. monai-weekly works in colab.
